<span id="built-in-template-tags-and-filters"></span><h1>Built-in template tags and filters<a class="headerlink" href="#built-in-template-tags-and-filters" title="Link to this heading">¶</a></h1>
<p>This document describes Django’s built-in template tags and filters. It is
recommended that you use the <a class="reference internal" href="../contrib/admin/admindocs.html"><span class="doc">automatic documentation</span></a>, if available, as this will also include
documentation for any custom tags or filters installed.</p>
<section id="s-built-in-tag-reference">
<span id="s-ref-templates-builtins-tags"></span><span id="built-in-tag-reference"></span><span id="ref-templates-builtins-tags"></span><h2>Built-in tag reference<a class="headerlink" href="#built-in-tag-reference" title="Link to this heading">¶</a></h2>
<section id="s-autoescape">
<span id="s-std-templatetag-autoescape"></span><span id="autoescape"></span><span id="std-templatetag-autoescape"></span><h3><code class="docutils literal notranslate"><span class="pre">autoescape</span></code><a class="headerlink" href="#autoescape" title="Link to this heading">¶</a></h3>
<p>Controls the current auto-escaping behavior. This tag takes either <code class="docutils literal notranslate"><span class="pre">on</span></code> or
<code class="docutils literal notranslate"><span class="pre">off</span></code> as an argument and that determines whether auto-escaping is in effect
inside the block. The block is closed with an <code class="docutils literal notranslate"><span class="pre">endautoescape</span></code> ending tag.</p>
<p>Sample usage:</p>
<div class="highlight-html+django notranslate"><div class="highlight"><pre><span></span><span class="cp">{%</span> <span class="k">autoescape</span> <span class="nv">on</span> <span class="cp">%}</span>
    <span class="cp">{{</span> <span class="nv">body</span> <span class="cp">}}</span>
<span class="cp">{%</span> <span class="k">endautoescape</span> <span class="cp">%}</span>
</pre></div>
</div>
<p>When auto-escaping is in effect, all content derived from variables has HTML
escaping applied before placing the result into the output (but after any
filters are applied). This is equivalent to manually applying the
<a class="reference internal" href="#std-templatefilter-escape"><code class="xref std std-tfilter docutils literal notranslate"><span class="pre">escape</span></code></a> filter to each variable.</p>
<p>The only exceptions are variables already marked as “safe” from escaping.
Variables could be marked as “safe” by the code which populated the variable,
by applying the <a class="reference internal" href="#std-templatefilter-safe"><code class="xref std std-tfilter docutils literal notranslate"><span class="pre">safe</span></code></a> or <a class="reference internal" href="#std-templatefilter-escape"><code class="xref std std-tfilter docutils literal notranslate"><span class="pre">escape</span></code></a> filters, or because it’s
the result of a previous filter that marked the string as “safe”.</p>
<p>Within the scope of disabled auto-escaping, chaining filters, including
<a class="reference internal" href="#std-templatefilter-escape"><code class="xref std std-tfilter docutils literal notranslate"><span class="pre">escape</span></code></a>, may cause unexpected (but documented) results such as the
following:</p>
<div class="highlight-html+django notranslate"><div class="highlight"><pre><span></span><span class="cp">{%</span> <span class="k">autoescape</span> <span class="nv">off</span> <span class="cp">%}</span>
    <span class="cp">{{</span> <span class="nv">my_list</span><span class="o">|</span><span class="nf">join</span><span class="s2">:&quot;, &quot;</span><span class="o">|</span><span class="nf">escape</span> <span class="cp">}}</span>
<span class="cp">{%</span> <span class="k">endautoescape</span> <span class="cp">%}</span>
</pre></div>
</div>
<p>The above code will output the joined elements of <code class="docutils literal notranslate"><span class="pre">my_list</span></code> unescaped. This
is because the filter chaining sequence executes first <a class="reference internal" href="#std-templatefilter-join"><code class="xref std std-tfilter docutils literal notranslate"><span class="pre">join</span></code></a> on
<code class="docutils literal notranslate"><span class="pre">my_list</span></code> (without applying escaping to each item since <code class="docutils literal notranslate"><span class="pre">autoescape</span></code> is
<code class="docutils literal notranslate"><span class="pre">off</span></code>), marking the result as safe. Subsequently, this safe result will be
fed to <a class="reference internal" href="#std-templatefilter-escape"><code class="xref std std-tfilter docutils literal notranslate"><span class="pre">escape</span></code></a> filter, which does not apply a second round of
escaping.</p>
<p>In order to properly escape every element in a sequence, use the
<a class="reference internal" href="#std-templatefilter-escapeseq"><code class="xref std std-tfilter docutils literal notranslate"><span class="pre">escapeseq</span></code></a> filter:</p>
<div class="highlight-html+django notranslate"><div class="highlight"><pre><span></span><span class="cp">{%</span> <span class="k">autoescape</span> <span class="nv">off</span> <span class="cp">%}</span>
    <span class="cp">{{</span> <span class="nv">my_list</span><span class="o">|</span><span class="nf">escapeseq</span><span class="o">|</span><span class="nf">join</span><span class="s2">:&quot;, &quot;</span> <span class="cp">}}</span>

<section id="s-cycle">
<span id="s-std-templatetag-cycle"></span><span id="cycle"></span><span id="std-templatetag-cycle"></span><h3><code class="docutils literal notranslate"><span class="pre">cycle</span></code><a class="headerlink" href="#cycle" title="Link to this heading">¶</a></h3>
<p>Produces one of its arguments each time this tag is encountered. The first
argument is produced on the first encounter, the second argument on the second
encounter, and so forth. Once all arguments are exhausted, the tag cycles to
the first argument and produces it again.</p>
<p>This tag is particularly useful in a loop:</p>
<div class="highlight-html+django notranslate"><div class="highlight"><pre><span></span><span class="cp">{%</span> <span class="k">for</span> <span class="nv">o</span> <span class="k">in</span> <span class="nv">some_list</span> <span class="cp">%}</span>
    <span class="p">&lt;</span><span class="nt">tr</span> <span class="na">class</span><span class="o">=</span><span class="s">&quot;</span><span class="cp">{%</span> <span class="k">cycle</span> <span class="s1">&#39;row1&#39;</span> <span class="s1">&#39;row2&#39;</span> <span class="cp">%}</span><span class="s">&quot;</span><span class="p">&gt;</span>
        ...
    <span class="p">&lt;/</span><span class="nt">tr</span><span class="p">&gt;</span>
<span class="cp">{%</span> <span class="k">endfor</span> <span class="cp">%}</span>
</pre></div>
</div>
<p>The first iteration produces HTML that refers to class <code class="docutils literal notranslate"><span class="pre">row1</span></code>, the second to
<code class="docutils literal notranslate"><span class="pre">row2</span></code>, the third to <code class="docutils literal notranslate"><span class="pre">row1</span></code> again, and so on for each iteration of the
loop.</p>
<p>You can use variables, too. For example, if you have two template variables,
<code class="docutils literal notranslate"><span class="pre">rowvalue1</span></code> and <code class="docutils literal notranslate"><span class="pre">rowvalue2</span></code>, you can alternate between their values like
this:</p>
<div class="highlight-html+django notranslate"><div class="highlight"><pre><span></span><span class="cp">{%</span> <span class="k">for</span> <span class="nv">o</span> <span class="k">in</span> <span class="nv">some_list</span> <span class="cp">%}</span>
    <span class="p">&lt;</span><span class="nt">tr</span> <span class="na">class</span><span class="o">=</span><span class="s">&quot;</span><span class="cp">{%</span> <span class="k">cycle</span> <span class="nv">rowvalue1</span> <span class="nv">rowvalue2</span> <span class="cp">%}</span><span class="s">&quot;</span><span class="p">&gt;</span>
        ...
    <span class="p">&lt;/</span><span class="nt">tr</span><span class="p">&gt;</span>
<span class="cp">{%</span> <span class="k">endfor</span> <span class="cp">%}</span>
</pre></div>
</div>
<p>Variables included in the cycle will be escaped. You can disable auto-escaping
with:</p>
<div class="highlight-html+django notranslate"><div class="highlight"><pre><span></span><span class="cp">{%</span> <span class="k">for</span> <span class="nv">o</span> <span class="k">in</span> <span class="nv">some_list</span> <span class="cp">%}</span>
    <span class="p">&lt;</span><span class="nt">tr</span> <span class="na">class</span><span class="o">=</span><span class="s">&quot;</span><span class="cp">{%</span> <span class="k">autoescape</span> <span class="nv">off</span> <span class="cp">%}{%</span> <span class="k">cycle</span> <span class="nv">rowvalue1</span> <span class="nv">rowvalue2</span> <span class="cp">%}{%</span> <span class="k">endautoescape</span> <span class="cp">%}</span><span class="s">&quot;</span><span class="p">&gt;</span>
        ...
    <span class="p">&lt;/</span><span class="nt">tr</span><span class="p">&gt;</span>
<span class="cp">{%</span> <span class="k">endfor</span> <span class="cp">%}</span>
</pre></div>
</div>
<p>You can mix variables and strings:</p>
<div class="highlight-html+django notranslate"><div class="highlight"><pre><span></span><span class="cp">{%</span> <span class="k">for</span> <span class="nv">o</span> <span class="k">in</span> <span class="nv">some_list</span> <span class="cp">%}</span>
    <span class="p">&lt;</span><span class="nt">tr</span> <span class="na">class</span><span class="o">=</span><span class="s">&quot;</span><span class="cp">{%</span> <span class="k">cycle</span> <span class="s1">&#39;row1&#39;</span> <span class="nv">rowvalue2</span> <span class="s1">&#39;row3&#39;</span> <span class="cp">%}</span><span class="s">&quot;</span><span class="p">&gt;</span>
        ...
    <span class="p">&lt;/</span><span class="nt">tr</span><span class="p">&gt;</span>
<span class="cp">{%</span> <span class="k">endfor</span> <span class="cp">%}</span>
</pre></div>
</div>
<p>In some cases you might want to refer to the current value of a cycle
without advancing to the next value. To do this,
give the <code class="docutils literal notranslate"><span class="pre">{%</span> <span class="pre">cycle</span> <span class="pre">%}</span></code> tag a name, using “as”, like this:</p>
<div class="highlight-html+django notranslate"><div class="highlight"><pre><span></span><span class="cp">{%</span> <span class="k">cycle</span> <span class="s1">&#39;row1&#39;</span> <span class="s1">&#39;row2&#39;</span> <span class="k">as</span> <span class="nv">rowcolors</span> <span class="cp">%}</span>
</pre></div>
</div>
<p>From then on, you can insert the current value of the cycle wherever you’d like
in your template by referencing the cycle name as a context variable. If you
want to move the cycle to the next value independently of the original
<code class="docutils literal notranslate"><span class="pre">cycle</span></code> tag, you can use another <code class="docutils literal notranslate"><span class="pre">cycle</span></code> tag and specify the name of the
variable. So, the following template:</p>
<div class="highlight-html+django notranslate"><div class="highlight"><pre><span></span><span class="p">&lt;</span><span class="nt">tr</span><span class="p">&gt;</span>
    <span class="p">&lt;</span><span class="nt">td</span> <span class="na">class</span><span class="o">=</span><span class="s">&quot;</span><span class="cp">{%</span> <span class="k">cycle</span> <span class="s1">&#39;row1&#39;</span> <span class="s1">&#39;row2&#39;</span> <span class="k">as</span> <span class="nv">rowcolors</span> <span class="cp">%}</span><span class="s">&quot;</span><span class="p">&gt;</span>...<span class="p">&lt;/</span><span class="nt">td</span><span class="p">&gt;</span>
    <span class="p">&lt;</span><span class="nt">td</span> <span class="na">class</span><span class="o">=</span><span class="s">&quot;</span><span class="cp">{{</span> <span class="nv">rowcolors</span> <span class="cp">}}</span><span class="s">&quot;</span><span class="p">&gt;</span>...<span class="p">&lt;/</span><span class="nt">td</span><span class="p">&gt;</span>
<span class="p">&lt;/</span><span class="nt">tr</span><span class="p">&gt;</span>
<span class="p">&lt;</span><span class="nt">tr</span><span class="p">&gt;</span>
    <span class="p">&lt;</span><span class="nt">td</span> <span class="na">class</span><span class="o">=</span><span class="s">&quot;</span><span class="cp">{%</span> <span class="k">cycle</span> <span class="nv">rowcolors</span> <span class="cp">%}</span><span class="s">&quot;</span><span class="p">&gt;</span>...<span class="p">&lt;/</span><span class="nt">td</span><span class="p">&gt;</span>
    <span class="p">&lt;</span><span class="nt">td</span> <span class="na">class</span><span class="o">=</span><span class="s">&quot;</span><span class="cp">{{</span> <span class="nv">rowcolors</span> <span class="cp">}}</span><span class="s">&quot;</span><span class="p">&gt;</span>...<span class="p">&lt;/</span><span class="nt">td</span><span class="p">&gt;</span>
<span class="p">&lt;/</span><span class="nt">tr</span><span class="p">&gt;</span>

</div>
<p>You can use any number of values in a <code class="docutils literal notranslate"><span class="pre">cycle</span></code> tag, separated by spaces.
Values enclosed in single quotes (<code class="docutils literal notranslate"><span class="pre">'</span></code>) or double quotes (<code class="docutils literal notranslate"><span class="pre">&quot;</span></code>) are treated
as string literals, while values without quotes are treated as template
variables.</p>
<p>By default, when you use the <code class="docutils literal notranslate"><span class="pre">as</span></code> keyword with the cycle tag, the
usage of <code class="docutils literal notranslate"><span class="pre">{%</span> <span class="pre">cycle</span> <span class="pre">%}</span></code> that initiates the cycle will itself produce
the first value in the cycle. This could be a problem if you want to
use the value in a nested loop or an included template. If you only want
to declare the cycle but not produce the first value, you can add a
<code class="docutils literal notranslate"><span class="pre">silent</span></code> keyword as the last keyword in the tag. For example:</p>
<div class="highlight-html+django notranslate"><div class="highlight"><pre><span></span><span class="cp">{%</span> <span class="k">for</span> <span class="nv">obj</span> <span class="k">in</span> <span class="nv">some_list</span> <span class="cp">%}</span>
    <span class="cp">{%</span> <span class="k">cycle</span> <span class="s1">&#39;row1&#39;</span> <span class="s1">&#39;row2&#39;</span> <span class="k">as</span> <span class="nv">rowcolors</span> <span class="nv">silent</span> <span class="cp">%}</span>
    <span class="p">&lt;</span><span class="nt">tr</span> <span class="na">class</span><span class="o">=</span><span class="s">&quot;</span><span class="cp">{{</span> <span class="nv">rowcolors</span> <span class="cp">}}</span><span class="s">&quot;</span><span class="p">&gt;</span><span class="cp">{%</span> <span class="k">include</span> <span class="s2">&quot;subtemplate.html&quot;</span> <span class="cp">%}</span><span class="p">&lt;/</span><span class="nt">tr</span><span class="p">&gt;</span>
<span class="cp">{%</span> <span class="k">endfor</span> <span class="cp">%}</span>
</pre></div>
</div>
<p>This will output a list of <code class="docutils literal notranslate"><span class="pre">&lt;tr&gt;</span></code> elements with <code class="docutils literal notranslate"><span class="pre">class</span></code>
alternating between <code class="docutils literal notranslate"><span class="pre">row1</span></code> and <code class="docutils literal notranslate"><span class="pre">row2</span></code>. The subtemplate will have
access to <code class="docutils literal notranslate"><span class="pre">rowcolors</span></code> in its context and the value will match the class
of the <code class="docutils literal notranslate"><span class="pre">&lt;tr&gt;</span></code> that encloses it. If the <code class="docutils literal notranslate"><span class="pre">silent</span></code> keyword were to be
omitted, <code class="docutils literal notranslate"><span class="pre">row1</span></code> and <code class="docutils literal notranslate"><span class="pre">row2</span></code> would be emitted as normal text, outside the
<code class="docutils literal notranslate"><span class="pre">&lt;tr&gt;</span></code> element.</p>
<p>When the silent keyword is used on a cycle definition, the silence
automatically applies to all subsequent uses of that specific cycle tag.
The following template would output <em>nothing</em>, even though the second
call to <code class="docutils literal notranslate"><span class="pre">{%</span> <span class="pre">cycle</span> <span class="pre">%}</span></code> doesn’t specify <code class="docutils literal notranslate"><span class="pre">silent</span></code>:</p>
<div class="highlight-html+django notranslate"><div class="highlight"><pre><span></span><span class="cp">{%</span> <span class="k">cycle</span> <span class="s1">&#39;row1&#39;</span> <span class="s1">&#39;row2&#39;</span> <span class="k">as</span> <span class="nv">rowcolors</span> <span class="nv">silent</span> <span class="cp">%}</span>

<p>You can use the <a class="reference internal" href="#std-templatetag-resetcycle"><code class="xref std std-ttag docutils literal notranslate"><span class="pre">resetcycle</span></code></a> tag to make a <code class="docutils literal notranslate"><span class="pre">{%</span> <span class="pre">cycle</span> <span class="pre">%}</span></code> tag restart

<p>Signals that this template extends a parent template.</p>
<p>This tag can be used in two ways:</p>
<ul class="simple">
<li><p><code class="docutils literal notranslate"><span class="pre">{%</span> <span class="pre">extends</span> <span class="pre">&quot;base.html&quot;</span> <span class="pre">%}</span></code> (with quotes) uses the literal value
<code class="docutils literal notranslate"><span class="pre">&quot;base.html&quot;</span></code> as the name of the parent template to extend.</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">{%</span> <span class="pre">extends</span> <span class="pre">variable</span> <span class="pre">%}</span></code> uses the value of <code class="docutils literal notranslate"><span class="pre">variable</span></code>. If the variable
evaluates to a string, Django will use that string as the name of the
parent template. If the variable evaluates to a <code class="docutils literal notranslate"><span class="pre">Template</span></code> object,
Django will use that object as the parent template.</p></li>
</ul>
<p>See <a class="reference internal" href="language.html#template-inheritance"><span class="std std-ref">Template inheritance</span></a> for more information.</p>
<p>Normally the template name is relative to the template loader’s root directory.
A string argument may also be a relative path starting with <code class="docutils literal notranslate"><span class="pre">./</span></code> or <code class="docutils literal notranslate"><span class="pre">../</span></code>.
For example, assume the following directory structure:</p>
<div class="highlight-text notranslate"><div class="highlight"><pre><span></span>dir1/
    template.html
    base2.html
    my/
        base3.html
base1.html
</pre></div>
</div>
<p>In <code class="docutils literal notranslate"><span class="pre">template.html</span></code>, the following paths would be valid:</p>
<div class="highlight-html+django notranslate"><div class="highlight"><pre><span></span><span class="cp">{%</span> <span class="k">extends</span> <span class="s2">&quot;./base2.html&quot;</span> <span class="cp">%}</span>

<p>Outputs the first argument variable that is not “false” (i.e. exists, is not

<p>You can also use a literal string as a fallback value in case all
passed variables are False:</p>
<div class="highlight-html+django notranslate"><div class="highlight"><pre><span></span><span class="cp">{%</span> <span class="k">firstof</span> <span class="nv">var1</span> <span class="nv">var2</span> <span class="nv">var3</span> <span class="s2">&quot;fallback value&quot;</span> <span class="cp">%}</span>
</pre></div>
</div>
<p>This tag auto-escapes variable values. You can disable auto-escaping with:</p>
<div class="highlight-html+django notranslate"><div class="highlight"><pre><span></span><span class="cp">{%</span> <span class="k">autoescape</span> <span class="nv">off</span> <span class="cp">%}</span>

<span class="cp">{%</span> <span class="k">endautoescape</span> <span class="cp">%}</span>
</pre></div>
</div>
<p>Or if only some variables should be escaped, you can use:</p>
<div class="highlight-html+django notranslate"><div class="highlight"><pre><span></span><span class="cp">{%</span> <span class="k">firstof</span> <span class="nv">var1</span> <span class="nv">var2</span><span class="o">|</span><span class="nf">safe</span> <span class="nv">var3</span> <span class="s2">&quot;&lt;strong&gt;fallback value&lt;/strong&gt;&quot;</span><span class="o">|</span><span class="nf">safe</span> <span class="cp">%}</span>

<p>Loops over each item in an array, making the item available in a context
variable. For example, to display a list of athletes provided in
<code class="docutils literal notranslate"><span class="pre">athlete_list</span></code>:</p>
<div class="highlight-html+django notranslate"><div class="highlight"><pre><span></span><span class="p">&lt;</span><span class="nt">ul</span><span class="p">&gt;</span>
<span class="cp">{%</span> <span class="k">for</span> <span class="nv">athlete</span> <span class="k">in</span> <span class="nv">athlete_list</span> <span class="cp">%}</span>

<span class="p">&lt;/</span><span class="nt">ul</span><span class="p">&gt;</span>
</pre></div>
</div>
<p>You can loop over a list in reverse by using
<code class="docutils literal notranslate"><span class="pre">{%</span> <span class="pre">for</span> <span class="pre">obj</span> <span class="pre">in</span> <span class="pre">list</span> <span class="pre">reversed</span> <span class="pre">%}</span></code>.</p>
<p>If you need to loop over a list of lists, you can unpack the values
in each sublist into individual variables. For example, if your context
contains a list of (x,y) coordinates called <code class="docutils literal notranslate"><span class="pre">points</span></code>, you could use the
following to output the list of points:</p>
<div class="highlight-html+django notranslate"><div class="highlight"><pre><span></span><span class="cp">{%</span> <span class="k">for</span> <span class="nv">x</span><span class="o">,</span> <span class="nv">y</span> <span class="k">in</span> <span class="nv">points</span> <span class="cp">%}</span>
    There is a point at <span class="cp">{{</span> <span class="nv">x</span> <span class="cp">}}</span>,<span class="cp">{{</span> <span class="nv">y</span> <span class="cp">}}</span>
<span class="cp">{%</span> <span class="k">endfor</span> <span class="cp">%}</span>
</pre></div>
</div>
<p>This can also be useful if you need to access the items in a dictionary.
For example, if your context contained a dictionary <code class="docutils literal notranslate"><span class="pre">data</span></code>, the following
would display the keys and values of the dictionary:</p>
<div class="highlight-html+django notranslate"><div class="highlight"><pre><span></span><span class="cp">{%</span> <span class="k">for</span> <span class="nv">key</span><span class="o">,</span> <span class="nv">value</span> <span class="k">in</span> <span class="nv">data.items</span> <span class="cp">%}</span>
    <span class="cp">{{</span> <span class="nv">key</span> <span class="cp">}}</span>: <span class="cp">{{</span> <span class="nv">value</span> <span class="cp">}}</span>
<span class="cp">{%</span> <span class="k">endfor</span> <span class="cp">%}</span>
</pre></div>
</div>
<p>Keep in mind that for the dot operator, dictionary key lookup takes precedence
over method lookup. Therefore if the <code class="docutils literal notranslate"><span class="pre">data</span></code> dictionary contains a key named
<code class="docutils literal notranslate"><span class="pre">'items'</span></code>, <code class="docutils literal notranslate"><span class="pre">data.items</span></code> will return <code class="docutils literal notranslate"><span class="pre">data['items']</span></code> instead of
<code class="docutils literal notranslate"><span class="pre">data.items()</span></code>. Avoid adding keys that are named like dictionary methods if
you want to use those methods in a template (<code class="docutils literal notranslate"><span class="pre">items</span></code>, <code class="docutils literal notranslate"><span class="pre">values</span></code>, <code class="docutils literal notranslate"><span class="pre">keys</span></code>,
etc.). Read more about the lookup order of the dot operator in the
<a class="reference internal" href="language.html#template-variables"><span class="std std-ref">documentation of template variables</span></a>.</p>
<p>The for loop sets a number of variables available within the loop:</p>

<section id="s-complex-expressions">
<span id="complex-expressions"></span><h4>Complex expressions<a class="headerlink" href="#complex-expressions" title="Link to this heading">¶</a></h4>
<p>All of the above can be combined to form complex expressions. For such
expressions, it can be important to know how the operators are grouped when the
expression is evaluated - that is, the precedence rules. The precedence of the
operators, from lowest to highest, is as follows:</p>
<ul class="simple">
<li><p><code class="docutils literal notranslate"><span class="pre">or</span></code></p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">and</span></code></p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">not</span></code></p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">in</span></code></p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">==</span></code>, <code class="docutils literal notranslate"><span class="pre">!=</span></code>, <code class="docutils literal notranslate"><span class="pre">&lt;</span></code>, <code class="docutils literal notranslate"><span class="pre">&gt;</span></code>, <code class="docutils literal notranslate"><span class="pre">&lt;=</span></code>, <code class="docutils literal notranslate"><span class="pre">&gt;=</span></code></p></li>
</ul>
<p>(This follows Python exactly). So, for example, the following complex
<a class="reference internal" href="#std-templatetag-if"><code class="xref std std-ttag docutils literal notranslate"><span class="pre">if</span></code></a> tag:</p>
<div class="highlight-html+django notranslate"><div class="highlight"><pre><span></span><span class="cp">{%</span> <span class="k">if</span> <span class="nv">a</span> <span class="o">==</span> <span class="nv">b</span> <span class="k">or</span> <span class="nv">c</span> <span class="o">==</span> <span class="nv">d</span> <span class="k">and</span> <span class="nv">e</span> <span class="cp">%}</span>
</pre></div>
</div>
<p>…will be interpreted as:</p>
<div class="highlight-python notranslate"><div class="highlight"><pre><span></span><span class="p">(</span><span class="n">a</span> <span class="o">==</span> <span class="n">b</span><span class="p">)</span> <span class="ow">or</span> <span class="p">((</span><span class="n">c</span> <span class="o">==</span> <span class="n">d</span><span class="p">)</span> <span class="ow">and</span> <span class="n">e</span><span class="p">)</span>
</pre></div>
</div>
<p>If you need different precedence, you will need to use nested <a class="reference internal" href="#std-templatetag-if"><code class="xref std std-ttag docutils literal notranslate"><span class="pre">if</span></code></a> tags.
Sometimes that is better for clarity anyway, for the sake of those who do not
know the precedence rules.</p>
<p>The comparison operators cannot be ‘chained’ like in Python or in mathematical
notation. For example, instead of using:</p>
<div class="highlight-html+django notranslate"><div class="highlight"><pre><span></span><span class="cp">{%</span> <span class="k">if</span> <span class="nv">a</span> <span class="o">&gt;</span> <span class="nv">b</span> <span class="o">&gt;</span> <span class="nv">c</span> <span class="cp">%}</span>  (WRONG)
</pre></div>
</div>
<p>you should use:</p>
<div class="highlight-html+django notranslate"><div class="highlight"><pre><span></span><span class="cp">{%</span> <span class="k">if</span> <span class="nv">a</span> <span class="o">&gt;</span> <span class="nv">b</span> <span class="k">and</span> <span class="nv">b</span> <span class="o">&gt;</span> <span class="nv">c</span> <span class="cp">%}</span>

<p>Loads a template and renders it with the current context. This is a way of
“including” other templates within a template.</p>
<p>The template name can either be a variable or a hardcoded (quoted) string,
in either single or double quotes.</p>
<p>This example includes the contents of the template <code class="docutils literal notranslate"><span class="pre">&quot;foo/bar.html&quot;</span></code>:</p>
<div class="highlight-html+django notranslate"><div class="highlight"><pre><span></span><span class="cp">{%</span> <span class="k">include</span> <span class="s2">&quot;foo/bar.html&quot;</span> <span class="cp">%}</span>
</pre></div>
</div>
<p>Normally the template name is relative to the template loader’s root directory.
A string argument may also be a relative path starting with <code class="docutils literal notranslate"><span class="pre">./</span></code> or <code class="docutils literal notranslate"><span class="pre">../</span></code>
as described in the <a class="reference internal" href="#std-templatetag-extends"><code class="xref std std-ttag docutils literal notranslate"><span class="pre">extends</span></code></a> tag.</p>
<p>This example includes the contents of the template whose name is contained in
the variable <code class="docutils literal notranslate"><span class="pre">template_name</span></code>:</p>
<div class="highlight-html+django notranslate"><div class="highlight"><pre><span></span><span class="cp">{%</span> <span class="k">include</span> <span class="nv">template_name</span> <span class="cp">%}</span>
</pre></div>
</div>
<p>The variable may also be any object with a <code class="docutils literal notranslate"><span class="pre">render()</span></code> method that accepts a
context. This allows you to reference a compiled <code class="docutils literal notranslate"><span class="pre">Template</span></code> in your context.</p>
<p>Additionally, the variable may be an iterable of template names, in which case
the first that can be loaded will be used, as per
<a class="reference internal" href="../../topics/templates.html#django.template.loader.select_template" title="django.template.loader.select_template"><code class="xref py py-func docutils literal notranslate"><span class="pre">select_template()</span></code></a>.</p>
<p>An included template is rendered within the context of the template that
includes it. This example produces the output <code class="docutils literal notranslate"><span class="pre">&quot;Hello,</span> <span class="pre">John!&quot;</span></code>:</p>
<ul>
<li><p>Context: variable <code class="docutils literal notranslate"><span class="pre">person</span></code> is set to <code class="docutils literal notranslate"><span class="pre">&quot;John&quot;</span></code> and variable <code class="docutils literal notranslate"><span class="pre">greeting</span></code>
is set to <code class="docutils literal notranslate"><span class="pre">&quot;Hello&quot;</span></code>.</p></li>
<li><p>Template:</p>
<div class="highlight-html+django notranslate"><div class="highlight"><pre><span></span><span class="cp">{%</span> <span class="k">include</span> <span class="s2">&quot;name_snippet.html&quot;</span> <span class="cp">%}</span>
</pre></div>
</div>
</li>
<li><p>The <code class="docutils literal notranslate"><span class="pre">name_snippet.html</span></code> template:</p>
<div class="highlight-html+django notranslate"><div class="highlight"><pre><span></span><span class="cp">{{</span> <span class="nv">greeting</span> <span class="cp">}}</span>, <span class="cp">{{</span> <span class="nv">person</span><span class="o">|</span><span class="nf">default</span><span class="s2">:&quot;friend&quot;</span> <span class="cp">}}</span>!
</pre></div>
</div>
</li>
</ul>
<p>You can pass additional context to the template using keyword arguments:</p>
<div class="highlight-html+django notranslate"><div class="highlight"><pre><span></span><span class="cp">{%</span> <span class="k">include</span> <span class="s2">&quot;name_snippet.html&quot;</span> <span class="k">with</span> <span class="nv">person</span><span class="o">=</span><span class="s2">&quot;Jane&quot;</span> <span class="nv">greeting</span><span class="o">=</span><span class="s2">&quot;Hello&quot;</span> <span class="cp">%}</span>
</pre></div>
</div>
<p>If you want to render the context only with the variables provided (or even
no variables at all), use the <code class="docutils literal notranslate"><span class="pre">only</span></code> option. No other variables are
available to the included template:</p>
<div class="highlight-html+django notranslate"><div class="highlight"><pre><span></span><span class="cp">{%</span> <span class="k">include</span> <span class="s2">&quot;name_snippet.html&quot;</span> <span class="k">with</span> <span class="nv">greeting</span><span class="o">=</span><span class="s2">&quot;Hi&quot;</span> <span class="nv">only</span> <span class="cp">%}</span>
</pre></div>

<div class="admonition note">
<p class="admonition-title">Note</p>
<p>The <a class="reference internal" href="#std-templatetag-include"><code class="xref std std-ttag docutils literal notranslate"><span class="pre">include</span></code></a> tag should be considered as an implementation of
“render this subtemplate and include the HTML”, not as “parse this
subtemplate and include its contents as if it were part of the parent”.
This means that there is no shared state between included templates –
each include is a completely independent rendering process.</p>
<p>Blocks are evaluated <em>before</em> they are included. This means that a template
that includes blocks from another will contain blocks that have <em>already
been evaluated and rendered</em> - not blocks that can be overridden by, for
example, an extending template.</p>

<p>Loads a custom template tag set.</p>
<p>For example, the following template would load all the tags and filters
registered in <code class="docutils literal notranslate"><span class="pre">somelibrary</span></code> and <code class="docutils literal notranslate"><span class="pre">otherlibrary</span></code> located in package
<code class="docutils literal notranslate"><span class="pre">package</span></code>:</p>

</pre></div>
</div>
<p>You can also selectively load individual filters or tags from a library, using
the <code class="docutils literal notranslate"><span class="pre">from</span></code> argument. In this example, the template tags/filters named <code class="docutils literal notranslate"><span class="pre">foo</span></code>
and <code class="docutils literal notranslate"><span class="pre">bar</span></code> will be loaded from <code class="docutils literal notranslate"><span class="pre">somelibrary</span></code>:</p>

in the <a class="reference internal" href="#std-templatefilter-date"><code class="xref std std-tfilter docutils literal notranslate"><span class="pre">date</span></code></a> filter section.</p>
<p>Example:</p>

</pre></div>
</div>
<p>Note that you can backslash-escape a format string if you want to use the
“raw” value. In this example, both “o” and “f” are backslash-escaped, because
otherwise each is a format string that displays the year and the time,
respectively:</p>
<div class="highlight-html+django notranslate"><div class="highlight"><pre><span></span>It is the <span class="cp">{%</span> <span class="k">now</span> <span class="s2">&quot;jS \o\f F&quot;</span> <span class="cp">%}</span>

</div>
<p>This would display as “It is the 4th of September”.</p>
<div class="admonition note">
<p class="admonition-title">Note</p>
<p>The format passed can also be one of the predefined ones
<a class="reference internal" href="../settings.html#std-setting-DATE_FORMAT"><code class="xref std std-setting docutils literal notranslate"><span class="pre">DATE_FORMAT</span></code></a>, <a class="reference internal" href="../settings.html#std-setting-DATETIME_FORMAT"><code class="xref std std-setting docutils literal notranslate"><span class="pre">DATETIME_FORMAT</span></code></a>,

The predefined formats may vary depending on the current locale and
if <a class="reference internal" href="../../topics/i18n/formatting.html"><span class="doc">Format localization</span></a> is enabled, e.g.:</p>
<div class="highlight-html+django notranslate"><div class="highlight"><pre><span></span>It is <span class="cp">{%</span> <span class="k">now</span> <span class="s2">&quot;SHORT_DATETIME_FORMAT&quot;</span> <span class="cp">%}</span>
</pre></div>
</div>
</div>
<p>You can also use the syntax <code class="docutils literal notranslate"><span class="pre">{%</span> <span class="pre">now</span> <span class="pre">&quot;Y&quot;</span> <span class="pre">as</span> <span class="pre">current_year</span> <span class="pre">%}</span></code> to store the
output (as a string) inside a variable. This is useful if you want to use
<code class="docutils literal notranslate"><span class="pre">{%</span> <span class="pre">now</span> <span class="pre">%}</span></code> inside a template tag like <a class="reference internal" href="../../topics/i18n/translation.html#std-templatetag-blocktranslate"><code class="xref std std-ttag docutils literal notranslate"><span class="pre">blocktranslate</span></code></a> for example:</p>

<p>A common example of using this tag is to preserve the current query string when
displaying a page of results, while adding a link to the next and previous
pages of results. For example, if the paginator is currently on page 3, and the
current query string is <code class="docutils literal notranslate"><span class="pre">?color=blue&amp;size=M&amp;page=3</span></code>, the following code would
output <code class="docutils literal notranslate"><span class="pre">?color=blue&amp;size=M&amp;page=4</span></code>:</p>
<div class="highlight-html+django notranslate"><div class="highlight"><pre><span></span><span class="cp">{%</span> <span class="k">querystring</span> <span class="nv">page</span><span class="o">=</span><span class="nv">page.next_page_number</span> <span class="cp">%}</span>
</pre></div>
</div>
<p>You can also store the value in a variable. For example, if you need multiple
links to the same page, define it as:</p>
<div class="highlight-html+django notranslate"><div class="highlight"><pre><span></span><span class="cp">{%</span> <span class="k">querystring</span> <span class="nv">page</span><span class="o">=</span><span class="nv">page.next_page_number</span> <span class="k">as</span> <span class="nv">next_page</span> <span class="cp">%}</span>

<p>This complex tag is best illustrated by way of an example: say that <code class="docutils literal notranslate"><span class="pre">cities</span></code>

<p>…and you’d like to display a hierarchical list that is ordered by country,
like this:</p>
<ul class="simple">
<li><p>India</p>
<ul>
<li><p>Mumbai: 19,000,000</p></li>
<li><p>Calcutta: 15,000,000</p></li>
</ul>
</li>
<li><p>USA</p>
<ul>
<li><p>New York: 20,000,000</p></li>
<li><p>Chicago: 7,000,000</p></li>
</ul>
</li>
<li><p>Japan</p>
<ul>
<li><p>Tokyo: 33,000,000</p></li>
</ul>
</li>
</ul>
<p>You can use the <code class="docutils literal notranslate"><span class="pre">{%</span> <span class="pre">regroup</span> <span class="pre">%}</span></code> tag to group the list of cities by country.
The following snippet of template code would accomplish this:</p>
<div class="highlight-html+django notranslate"><div class="highlight"><pre><span></span><span class="cp">{%</span> <span class="k">regroup</span> <span class="nv">cities</span> <span class="nv">by</span> <span class="nv">country</span> <span class="k">as</span> <span class="nv">country_list</span> <span class="cp">%}</span>

        <span class="cp">{%</span> <span class="k">for</span> <span class="nv">city</span> <span class="k">in</span> <span class="nv">country.list</span> <span class="cp">%}</span>

        <span class="cp">{%</span> <span class="k">endfor</span> <span class="cp">%}</span>
    <span class="p">&lt;/</span><span class="nt">ul</span><span class="p">&gt;</span>

<span class="cp">{%</span> <span class="k">endfor</span> <span class="cp">%}</span>
<span class="p">&lt;/</span><span class="nt">ul</span><span class="p">&gt;</span>
</pre></div>
</div>
<p>Let’s walk through this example. <code class="docutils literal notranslate"><span class="pre">{%</span> <span class="pre">regroup</span> <span class="pre">%}</span></code> takes three arguments: the
list you want to regroup, the attribute to group by, and the name of the
resulting list. Here, we’re regrouping the <code class="docutils literal notranslate"><span class="pre">cities</span></code> list by the <code class="docutils literal notranslate"><span class="pre">country</span></code>
attribute and calling the result <code class="docutils literal notranslate"><span class="pre">country_list</span></code>.</p>
<p><code class="docutils literal notranslate"><span class="pre">{%</span> <span class="pre">regroup</span> <span class="pre">%}</span></code> produces a list (in this case, <code class="docutils literal notranslate"><span class="pre">country_list</span></code>) of
<strong>group objects</strong>. Group objects are instances of
<a class="reference external" href="https://docs.python.org/3/library/collections.html#collections.namedtuple" title="(in Python v3.14)"><code class="xref py py-func docutils literal notranslate"><span class="pre">namedtuple()</span></code></a> with two fields:</p>
<ul class="simple">
<li><p><code class="docutils literal notranslate"><span class="pre">grouper</span></code> – the item that was grouped by (e.g., the string “India” or
“Japan”).</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">list</span></code> – a list of all items in this group (e.g., a list of all cities
with country=’India’).</p></li>
</ul>
<p>Because <code class="docutils literal notranslate"><span class="pre">{%</span> <span class="pre">regroup</span> <span class="pre">%}</span></code> produces <a class="reference external" href="https://docs.python.org/3/library/collections.html#collections.namedtuple" title="(in Python v3.14)"><code class="xref py py-func docutils literal notranslate"><span class="pre">namedtuple()</span></code></a> objects,
you can also write the previous example as:</p>
<div class="highlight-html+django notranslate"><div class="highlight"><pre><span></span><span class="cp">{%</span> <span class="k">regroup</span> <span class="nv">cities</span> <span class="nv">by</span> <span class="nv">country</span> <span class="k">as</span> <span class="nv">country_list</span> <span class="cp">%}</span>

<span class="p">&lt;</span><span class="nt">ul</span><span class="p">&gt;</span>
<span class="cp">{%</span> <span class="k">for</span> <span class="nv">country</span><span class="o">,</span> <span class="nv">local_cities</span> <span class="k">in</span> <span class="nv">country_list</span> <span class="cp">%}</span>
    <span class="p">&lt;</span><span class="nt">li</span><span class="p">&gt;</span><span class="cp">{{</span> <span class="nv">country</span> <span class="cp">}}</span>
    <span class="p">&lt;</span><span class="nt">ul</span><span class="p">&gt;</span>
        <span class="cp">{%</span> <span class="k">for</span> <span class="nv">city</span> <span class="k">in</span> <span class="nv">local_cities</span> <span class="cp">%}</span>
          <span class="p">&lt;</span><span class="nt">li</span><span class="p">&gt;</span><span class="cp">{{</span> <span class="nv">city.name</span> <span class="cp">}}</span>: <span class="cp">{{</span> <span class="nv">city.population</span> <span class="cp">}}</span><span class="p">&lt;/</span><span class="nt">li</span><span class="p">&gt;</span>
        <span class="cp">{%</span> <span class="k">endfor</span> <span class="cp">%}</span>
    <span class="p">&lt;/</span><span class="nt">ul</span><span class="p">&gt;</span>
    <span class="p">&lt;/</span><span class="nt">li</span><span class="p">&gt;</span>
<span class="cp">{%</span> <span class="k">endfor</span> <span class="cp">%}</span>
<span class="p">&lt;/</span><span class="nt">ul</span><span class="p">&gt;</span>
</pre></div>
</div>
<p>Note that <code class="docutils literal notranslate"><span class="pre">{%</span> <span class="pre">regroup</span> <span class="pre">%}</span></code> does not order its input! Our example relies on the
fact that the <code class="docutils literal notranslate"><span class="pre">cities</span></code> list was ordered by <code class="docutils literal notranslate"><span class="pre">country</span></code> in the first place. If
the <code class="docutils literal notranslate"><span class="pre">cities</span></code> list did <em>not</em> order its members by <code class="docutils literal notranslate"><span class="pre">country</span></code>, the regrouping
would naively display more than one group for a single country. For example,
say the <code class="docutils literal notranslate"><span class="pre">cities</span></code> list was set to this (note that the countries are not
grouped together):</p>
<div class="highlight-python notranslate"><div class="highlight"><pre><span></span><span class="n">cities</span> <span class="o">=</span> <span class="p">[</span>
    <span class="p">{</span><span class="s2">&quot;name&quot;</span><span class="p">:</span> <span class="s2">&quot;Mumbai&quot;</span><span class="p">,</span> <span class="s2">&quot;population&quot;</span><span class="p">:</span> <span class="s2">&quot;19,000,000&quot;</span><span class="p">,</span> <span class="s2">&quot;country&quot;</span><span class="p">:</span> <span class="s2">&quot;India&quot;</span><span class="p">},</span>
    <span class="p">{</span><span class="s2">&quot;name&quot;</span><span class="p">:</span> <span class="s2">&quot;New York&quot;</span><span class="p">,</span> <span class="s2">&quot;population&quot;</span><span class="p">:</span> <span class="s2">&quot;20,000,000&quot;</span><span class="p">,</span> <span class="s2">&quot;country&quot;</span><span class="p">:</span> <span class="s2">&quot;USA&quot;</span><span class="p">},</span>
    <span class="p">{</span><span class="s2">&quot;name&quot;</span><span class="p">:</span> <span class="s2">&quot;Calcutta&quot;</span><span class="p">,</span> <span class="s2">&quot;population&quot;</span><span class="p">:</span> <span class="s2">&quot;15,000,000&quot;</span><span class="p">,</span> <span class="s2">&quot;country&quot;</span><span class="p">:</span> <span class="s2">&quot;India&quot;</span><span class="p">},</span>
    <span class="p">{</span><span class="s2">&quot;name&quot;</span><span class="p">:</span> <span class="s2">&quot;Chicago&quot;</span><span class="p">,</span> <span class="s2">&quot;population&quot;</span><span class="p">:</span> <span class="s2">&quot;7,000,000&quot;</span><span class="p">,</span> <span class="s2">&quot;country&quot;</span><span class="p">:</span> <span class="s2">&quot;USA&quot;</span><span class="p">},</span>
    <span class="p">{</span><span class="s2">&quot;name&quot;</span><span class="p">:</span> <span class="s2">&quot;Tokyo&quot;</span><span class="p">,</span> <span class="s2">&quot;population&quot;</span><span class="p">:</span> <span class="s2">&quot;33,000,000&quot;</span><span class="p">,</span> <span class="s2">&quot;country&quot;</span><span class="p">:</span> <span class="s2">&quot;Japan&quot;</span><span class="p">},</span>
<span class="p">]</span>
</pre></div>
</div>
<p>With this input for <code class="docutils literal notranslate"><span class="pre">cities</span></code>, the example <code class="docutils literal notranslate"><span class="pre">{%</span> <span class="pre">regroup</span> <span class="pre">%}</span></code> template code
above would result in the following output:</p>
<ul class="simple">
<li><p>India</p>
<ul>
<li><p>Mumbai: 19,000,000</p></li>
</ul>
</li>
<li><p>USA</p>
<ul>
<li><p>New York: 20,000,000</p></li>
</ul>
</li>
<li><p>India</p>
<ul>
<li><p>Calcutta: 15,000,000</p></li>
</ul>
</li>
<li><p>USA</p>
<ul>
<li><p>Chicago: 7,000,000</p></li>
</ul>
</li>
<li><p>Japan</p>
<ul>
<li><p>Tokyo: 33,000,000</p></li>
</ul>
</li>
</ul>
<p>The easiest solution to this gotcha is to make sure in your view code that the
data is ordered according to how you want to display it.</p>
<p>Another solution is to sort the data in the template using the
<a class="reference internal" href="#std-templatefilter-dictsort"><code class="xref std std-tfilter docutils literal notranslate"><span class="pre">dictsort</span></code></a> filter, if your data is in a list of dictionaries:</p>
<div class="highlight-html+django notranslate"><div class="highlight"><pre><span></span><span class="cp">{%</span> <span class="k">regroup</span> <span class="nv">cities</span><span class="o">|</span><span class="nf">dictsort</span><span class="s2">:&quot;country&quot;</span> <span class="nv">by</span> <span class="nv">country</span> <span class="k">as</span> <span class="nv">country_list</span> <span class="cp">%}</span>

<span id="grouping-on-other-properties"></span><h4>Grouping on other properties<a class="headerlink" href="#grouping-on-other-properties" title="Link to this heading">¶</a></h4>
<p>Any valid template lookup is a legal grouping attribute for the regroup
tag, including methods, attributes, dictionary keys and list items. For
example, if the “country” field is a foreign key to a class with
an attribute “description,” you could use:</p>
<div class="highlight-html+django notranslate"><div class="highlight"><pre><span></span><span class="cp">{%</span> <span class="k">regroup</span> <span class="nv">cities</span> <span class="nv">by</span> <span class="nv">country.description</span> <span class="k">as</span> <span class="nv">country_list</span> <span class="cp">%}</span>
</pre></div>
</div>
<p>Or, if <code class="docutils literal notranslate"><span class="pre">country</span></code> is a field with <code class="docutils literal notranslate"><span class="pre">choices</span></code>, it will have a
<a class="reference internal" href="../models/instances.html#django.db.models.Model.get_FOO_display" title="django.db.models.Model.get_FOO_display"><code class="xref py py-meth docutils literal notranslate"><span class="pre">get_FOO_display()</span></code></a> method available as an
attribute, allowing  you to group on the display string rather than the
<code class="docutils literal notranslate"><span class="pre">choices</span></code> key:</p>
<div class="highlight-html+django notranslate"><div class="highlight"><pre><span></span><span class="cp">{%</span> <span class="k">regroup</span> <span class="nv">cities</span> <span class="nv">by</span> <span class="nv">get_country_display</span> <span class="k">as</span> <span class="nv">country_list</span> <span class="cp">%}</span>

</div>
<p><code class="docutils literal notranslate"><span class="pre">{{</span> <span class="pre">country.grouper</span> <span class="pre">}}</span></code> will now display the value fields from the

<p>Notice how the first block ends with <code class="docutils literal notranslate"><span class="pre">class=&quot;odd&quot;</span></code> and the new one starts
with <code class="docutils literal notranslate"><span class="pre">class=&quot;odd&quot;</span></code>. Without the <code class="docutils literal notranslate"><span class="pre">{%</span> <span class="pre">resetcycle</span> <span class="pre">%}</span></code> tag, the second block

<p>In this example, we have both the alternating odd/even rows and a “major” row
every fifth row. Only the five-row cycle is reset when a category changes.</p>

<p>Example usage:</p>

<p>Only space between <em>tags</em> is removed – not space between tags and text. In
this example, the space around <code class="docutils literal notranslate"><span class="pre">Hello</span></code> won’t be stripped:</p>

<p>Outputs one of the syntax characters used to compose template tags.</p>
<p>The template system has no concept of “escaping” individual characters.
However, you can use the <code class="docutils literal notranslate"><span class="pre">{%</span> <span class="pre">templatetag</span> <span class="pre">%}</span></code> tag to display one of the
template tag character combinations.</p>
<p>The argument tells which template bit to output:</p>
<table class="docutils">

<section id="s-url">

<p>Returns an absolute path reference (a URL without the domain name) matching a
given view and optional parameters. Any special characters in the resulting
path will be encoded using <a class="reference internal" href="../utils.html#django.utils.encoding.iri_to_uri" title="django.utils.encoding.iri_to_uri"><code class="xref py py-func docutils literal notranslate"><span class="pre">iri_to_uri()</span></code></a>.</p>
<p>This is a way to output links without violating the DRY principle by having to
hardcode URLs in your templates:</p>
<div class="highlight-html+django notranslate"><div class="highlight"><pre><span></span><span class="cp">{%</span> <span class="k">url</span> <span class="s1">&#39;some-url-name&#39;</span> <span class="nv">v1</span> <span class="nv">v2</span> <span class="cp">%}</span>
</pre></div>
</div>
<p>The first argument is a <a class="reference internal" href="../../topics/http/urls.html#naming-url-patterns"><span class="std std-ref">URL pattern name</span></a>. It can
be a quoted literal or any other context variable. Additional arguments are
optional and should be space-separated values that will be used as arguments in
the URL. The example above shows passing positional arguments. Alternatively
you may use keyword syntax:</p>
<div class="highlight-html+django notranslate"><div class="highlight"><pre><span></span><span class="cp">{%</span> <span class="k">url</span> <span class="s1">&#39;some-url-name&#39;</span> <span class="nv">arg1</span><span class="o">=</span><span class="nv">v1</span> <span class="nv">arg2</span><span class="o">=</span><span class="nv">v2</span> <span class="cp">%}</span>
</pre></div>
</div>
<p>Do not mix both positional and keyword syntax in a single call. All arguments
required by the URLconf should be present.</p>
<p>For example, suppose you have a view, <code class="docutils literal notranslate"><span class="pre">app_views.client</span></code>, whose URLconf
takes a client ID (here, <code class="docutils literal notranslate"><span class="pre">client()</span></code> is a method inside the views file
<code class="docutils literal notranslate"><span class="pre">app_views.py</span></code>). The URLconf line might look like this:</p>
<div class="highlight-python notranslate"><div class="highlight"><pre><span></span><span class="n">path</span><span class="p">(</span><span class="s2">&quot;client/&lt;int:id&gt;/&quot;</span><span class="p">,</span> <span class="n">app_views</span><span class="o">.</span><span class="n">client</span><span class="p">,</span> <span class="n">name</span><span class="o">=</span><span class="s2">&quot;app-views-client&quot;</span><span class="p">)</span>
</pre></div>
</div>
<p>If this app’s URLconf is included into the project’s URLconf under a path
such as this:</p>
<div class="highlight-python notranslate"><div class="highlight"><pre><span></span><span class="n">path</span><span class="p">(</span><span class="s2">&quot;clients/&quot;</span><span class="p">,</span> <span class="n">include</span><span class="p">(</span><span class="s2">&quot;project_name.app_name.urls&quot;</span><span class="p">))</span>
</pre></div>
</div>
<p>…then, in a template, you can create a link to this view like this:</p>
<div class="highlight-html+django notranslate"><div class="highlight"><pre><span></span><span class="cp">{%</span> <span class="k">url</span> <span class="s1">&#39;app-views-client&#39;</span> <span class="nv">client.id</span> <span class="cp">%}</span>
</pre></div>
</div>
<p>The template tag will output the string <code class="docutils literal notranslate"><span class="pre">/clients/client/123/</span></code>.</p>
<p>Note that if the URL you’re reversing doesn’t exist, you’ll get an
<a class="reference internal" href="../exceptions.html#django.urls.NoReverseMatch" title="django.urls.NoReverseMatch"><code class="xref py py-exc docutils literal notranslate"><span class="pre">NoReverseMatch</span></code></a> exception raised, which will cause your
site to display an error page.</p>
<p>If you’d like to retrieve a URL without displaying it, you can use a slightly
different call:</p>
<div class="highlight-html+django notranslate"><div class="highlight"><pre><span></span><span class="cp">{%</span> <span class="k">url</span> <span class="s1">&#39;some-url-name&#39;</span> <span class="nv">arg</span> <span class="nv">arg2</span> <span class="k">as</span> <span class="nv">the_url</span> <span class="cp">%}</span>

<span class="p">&lt;</span><span class="nt">a</span> <span class="na">href</span><span class="o">=</span><span class="s">&quot;</span><span class="cp">{{</span> <span class="nv">the_url</span> <span class="cp">}}</span><span class="s">&quot;</span><span class="p">&gt;</span>I&#39;m linking to <span class="cp">{{</span> <span class="nv">the_url</span> <span class="cp">}}</span><span class="p">&lt;/</span><span class="nt">a</span><span class="p">&gt;</span>
</pre></div>
</div>
<p>The scope of the variable created by the  <code class="docutils literal notranslate"><span class="pre">as</span> <span class="pre">var</span></code> syntax is the
<code class="docutils literal notranslate"><span class="pre">{%</span> <span class="pre">block</span> <span class="pre">%}</span></code> in which the <code class="docutils literal notranslate"><span class="pre">{%</span> <span class="pre">url</span> <span class="pre">%}</span></code> tag appears.</p>
<p>This <code class="docutils literal notranslate"><span class="pre">{%</span> <span class="pre">url</span> <span class="pre">...</span> <span class="pre">as</span> <span class="pre">var</span> <span class="pre">%}</span></code> syntax will <em>not</em> cause an error if the view is
missing. In practice you’ll use this to link to views that are optional:</p>
<div class="highlight-html+django notranslate"><div class="highlight"><pre><span></span><span class="cp">{%</span> <span class="k">url</span> <span class="s1">&#39;some-url-name&#39;</span> <span class="k">as</span> <span class="nv">the_url</span> <span class="cp">%}</span>
<span class="cp">{%</span> <span class="k">if</span> <span class="nv">the_url</span> <span class="cp">%}</span>
  <span class="p">&lt;</span><span class="nt">a</span> <span class="na">href</span><span class="o">=</span><span class="s">&quot;</span><span class="cp">{{</span> <span class="nv">the_url</span> <span class="cp">}}</span><span class="s">&quot;</span><span class="p">&gt;</span>Link to optional stuff<span class="p">&lt;/</span><span class="nt">a</span><span class="p">&gt;</span>
<span class="cp">{%</span> <span class="k">endif</span> <span class="cp">%}</span>
</pre></div>
</div>
<p>If you’d like to retrieve a namespaced URL, specify the fully qualified name:</p>
<div class="highlight-html+django notranslate"><div class="highlight"><pre><span></span><span class="cp">{%</span> <span class="k">url</span> <span class="s1">&#39;myapp:view-name&#39;</span> <span class="cp">%}</span>
</pre></div>
</div>
<p>This will follow the normal <a class="reference internal" href="../../topics/http/urls.html#topics-http-reversing-url-namespaces"><span class="std std-ref">namespaced URL resolution strategy</span></a>, including using any hints provided
by the context as to the current application.</p>
<div class="admonition warning">
<p class="admonition-title">Warning</p>
<p>Don’t forget to put quotes around the URL pattern <code class="docutils literal notranslate"><span class="pre">name</span></code>, otherwise the
value will be interpreted as a context variable!</p>
</div>
</section>
<section id="s-verbatim">
<span id="s-std-templatetag-verbatim"></span><span id="verbatim"></span><span id="std-templatetag-verbatim"></span><h3><code class="docutils literal notranslate"><span class="pre">verbatim</span></code><a class="headerlink" href="#verbatim" title="Link to this heading">¶</a></h3>
<p>Stops the template engine from rendering the contents of this block tag.</p>
<p>A common use is to allow a JavaScript template layer that collides with
Django’s syntax. For example:</p>
<div class="highlight-html+django notranslate"><div class="highlight"><pre><span></span><span class="cp">{%</span> <span class="k">verbatim</span> <span class="cp">%}</span>
    <span class="cp">{{</span><span class="k">if</span> <span class="nv">dying</span><span class="cp">}}</span>Still alive.<span class="cp">{{</span><span class="o">/</span><span class="k">if</span><span class="cp">}}</span>
<span class="cp">{%</span> <span class="k">endverbatim</span> <span class="cp">%}</span>
</pre></div>
</div>
<p>You can also designate a specific closing tag, allowing the use of
<code class="docutils literal notranslate"><span class="pre">{%</span> <span class="pre">endverbatim</span> <span class="pre">%}</span></code> as part of the unrendered contents:</p>
<div class="highlight-html+django notranslate"><div class="highlight"><pre><span></span><span class="cp">{%</span> <span class="k">verbatim</span> <span class="nv">myblock</span> <span class="cp">%}</span>
    Avoid template rendering via the <span class="cp">{%</span> <span class="k">verbatim</span> <span class="cp">%}{%</span> <span class="k">endverbatim</span> <span class="cp">%}</span> block.
<span class="cp">{%</span> <span class="k">endverbatim</span> <span class="nv">myblock</span> <span class="cp">%}</span>
</pre></div>
</div>

<section id="s-widthratio">

<p>For creating bar charts and such, this tag calculates the ratio of a given
value to a maximum value, and then applies that ratio to a constant.</p>
<p>For example:</p>
<div class="highlight-html+django notranslate"><div class="highlight"><pre><span></span><span class="p">&lt;</span><span class="nt">img</span> <span class="na">src</span><span class="o">=</span><span class="s">&quot;bar.png&quot;</span> <span class="na">alt</span><span class="o">=</span><span class="s">&quot;Bar&quot;</span>
     <span class="na">height</span><span class="o">=</span><span class="s">&quot;10&quot;</span> <span class="na">width</span><span class="o">=</span><span class="s">&quot;</span><span class="cp">{%</span> <span class="k">widthratio</span> <span class="nv">this_value</span> <span class="nv">max_value</span> <span class="nv">max_width</span> <span class="cp">%}</span><span class="s">&quot;</span><span class="p">&gt;</span>
</pre></div>
</div>
<p>If <code class="docutils literal notranslate"><span class="pre">this_value</span></code> is 175, <code class="docutils literal notranslate"><span class="pre">max_value</span></code> is 200, and <code class="docutils literal notranslate"><span class="pre">max_width</span></code> is 100, the
image in the above example will be 88 pixels wide
(because 175/200 = .875; .875 * 100 = 87.5 which is rounded up to 88).</p>
<p>In some cases you might want to capture the result of <code class="docutils literal notranslate"><span class="pre">widthratio</span></code> in a
variable. It can be useful, for instance, in a <a class="reference internal" href="../../topics/i18n/translation.html#std-templatetag-blocktranslate"><code class="xref std std-ttag docutils literal notranslate"><span class="pre">blocktranslate</span></code></a> like
this:</p>

<span class="cp">{%</span> <span class="k">blocktranslate</span> <span class="cp">%}</span>The width is: <span class="cp">{{</span> <span class="nv">width</span> <span class="cp">}}{%</span> <span class="k">endblocktranslate</span> <span class="cp">%}</span>

<p>Adds the argument to the value.</p>

<p>If <code class="docutils literal notranslate"><span class="pre">value</span></code> is <code class="docutils literal notranslate"><span class="pre">4</span></code>, then the output will be <code class="docutils literal notranslate"><span class="pre">6</span></code>.</p>
<p>This filter will first try to coerce both values to integers. If this fails,
it’ll attempt to add the values together anyway. This will work on some data
types (strings, list, etc.) and fail on others. If it fails, the result will
be an empty string.</p>
<p>For example, if we have:</p>
<div class="highlight-html+django notranslate"><div class="highlight"><pre><span></span><span class="cp">{{</span> <span class="nv">first</span><span class="o">|</span><span class="nf">add</span><span class="o">:</span><span class="nv">second</span> <span class="cp">}}</span>

</div>
<p>and <code class="docutils literal notranslate"><span class="pre">first</span></code> is <code class="docutils literal notranslate"><span class="pre">[1,</span> <span class="pre">2,</span> <span class="pre">3]</span></code> and <code class="docutils literal notranslate"><span class="pre">second</span></code> is <code class="docutils literal notranslate"><span class="pre">[4,</span> <span class="pre">5,</span> <span class="pre">6]</span></code>, then the

<div class="admonition warning">

<p>Strings that can be coerced to integers will be <strong>summed</strong>, not

<code class="docutils literal notranslate"><span class="pre">'Wed</span> <span class="pre">09</span> <span class="pre">Jan</span> <span class="pre">2008'</span></code>.</p>
<p>The format passed can be one of the predefined ones <a class="reference internal" href="../settings.html#std-setting-DATE_FORMAT"><code class="xref std std-setting docutils literal notranslate"><span class="pre">DATE_FORMAT</span></code></a>,

specifiers shown in the table above. Note that predefined formats may vary
depending on the current locale.</p>
<p>Assuming that <a class="reference internal" href="../settings.html#std-setting-LANGUAGE_CODE"><code class="xref std std-setting docutils literal notranslate"><span class="pre">LANGUAGE_CODE</span></code></a> is, for example, <code class="docutils literal notranslate"><span class="pre">&quot;es&quot;</span></code>, then for:</p>

<p>the output would be the string <code class="docutils literal notranslate"><span class="pre">&quot;09/01/2008&quot;</span></code> (the <code class="docutils literal notranslate"><span class="pre">&quot;SHORT_DATE_FORMAT&quot;</span></code>

<p>When used without a format string, the <code class="docutils literal notranslate"><span class="pre">DATE_FORMAT</span></code> format specifier is

<ul class="simple">
<li><p><code class="docutils literal notranslate"><span class="pre">&lt;</span></code> is converted to <code class="docutils literal notranslate"><span class="pre">&amp;lt;</span></code></p></li>

</ul>
<p>Applying <code class="docutils literal notranslate"><span class="pre">escape</span></code> to a variable that would normally have auto-escaping
applied to the result will only result in one round of escaping being done. So
it is safe to use this function even in auto-escaping environments. If you want

<p class="admonition-title">Chaining <code class="docutils literal notranslate"><span class="pre">escape</span></code> with other filters</p>
<p>As mentioned in the <a class="reference internal" href="#std-templatetag-autoescape"><code class="xref std std-ttag docutils literal notranslate"><span class="pre">autoescape</span></code></a> section, when filters including
<code class="docutils literal notranslate"><span class="pre">escape</span></code> are chained together, it can result in unexpected outcomes if
preceding filters mark a potentially unsafe string as safe due to the lack
of escaping caused by <a class="reference internal" href="#std-templatetag-autoescape"><code class="xref std std-ttag docutils literal notranslate"><span class="pre">autoescape</span></code></a> being <code class="docutils literal notranslate"><span class="pre">off</span></code>.</p>
<p>In such cases, chaining <code class="docutils literal notranslate"><span class="pre">escape</span></code> would not reescape strings that have
already been marked as safe.</p>
<p>This is especially important when using filters that operate on sequences,
for example <a class="reference internal" href="#std-templatefilter-join"><code class="xref std std-tfilter docutils literal notranslate"><span class="pre">join</span></code></a>. If you need to escape each element in a
sequence, use the dedicated <a class="reference internal" href="#std-templatefilter-escapeseq"><code class="xref std std-tfilter docutils literal notranslate"><span class="pre">escapeseq</span></code></a> filter.</p>

System of Units which recommends using KiB, MiB, GiB, etc. when byte sizes
are calculated in powers of 1024 (which is the case here). Instead, Django
uses traditional unit names (KB, MB, GB, etc.) corresponding to names that
are more commonly used.</p>

<p>For words that require a suffix other than <code class="docutils literal notranslate"><span class="pre">'s'</span></code>, you can provide an
alternate suffix as a parameter to the filter.</p>
<p>Example:</p>

</pre></div>
</div>
<p>For words that don’t pluralize by simple suffix, you can specify both a
singular and plural suffix, separated by a comma.</p>

<p>Formats a time according to the given format.</p>
<p>Given format can be the predefined one <a class="reference internal" href="../settings.html#std-setting-TIME_FORMAT"><code class="xref std std-setting docutils literal notranslate"><span class="pre">TIME_FORMAT</span></code></a>, or a custom
format, same as the <a class="reference internal" href="#std-templatefilter-date"><code class="xref std std-tfilter docutils literal notranslate"><span class="pre">date</span></code></a> filter. Note that the predefined format
is locale-dependent.</p>
<p>For example:</p>
<div class="highlight-html+django notranslate"><div class="highlight"><pre><span></span><span class="cp">{{</span> <span class="nv">value</span><span class="o">|</span><span class="nf">time</span><span class="s2">:&quot;H:i&quot;</span> <span class="cp">}}</span>

</div>
<p>If <code class="docutils literal notranslate"><span class="pre">value</span></code> is equivalent to <code class="docutils literal notranslate"><span class="pre">datetime.datetime.now()</span></code>, the output will be
the string <code class="docutils literal notranslate"><span class="pre">&quot;01:23&quot;</span></code>.</p>
<p>Note that you can backslash-escape a format string if you want to use the
“raw” value. In this example, both “h” and “m” are backslash-escaped, because
otherwise each is a format string that displays the hour and the month,
respectively:</p>
<div class="highlight-html+django notranslate"><div class="highlight"><pre><span></span><span class="cp">{{</span> <span class="nv">value</span><span class="o">|</span><span class="nf">time</span><span class="s2">:&quot;H\h i\m&quot;</span> <span class="cp">}}</span>
</pre></div>
</div>
<p>This would display as “01h 23m”.</p>
<p>Another example:</p>
<p>Assuming that <a class="reference internal" href="../settings.html#std-setting-LANGUAGE_CODE"><code class="xref std std-setting docutils literal notranslate"><span class="pre">LANGUAGE_CODE</span></code></a> is, for example, <code class="docutils literal notranslate"><span class="pre">&quot;de&quot;</span></code>, then for:</p>

</pre></div>
</div>
<p>the output will be the string <code class="docutils literal notranslate"><span class="pre">&quot;01:23&quot;</span></code> (The <code class="docutils literal notranslate"><span class="pre">&quot;TIME_FORMAT&quot;</span></code> format
specifier for the <code class="docutils literal notranslate"><span class="pre">de</span></code> locale as shipped with Django is <code class="docutils literal notranslate"><span class="pre">&quot;H:i&quot;</span></code>).</p>
<p>The <code class="docutils literal notranslate"><span class="pre">time</span></code> filter will only accept parameters in the format string that
relate to the time of day, not the date. If you need to format a <code class="docutils literal notranslate"><span class="pre">date</span></code>
value, use the <a class="reference internal" href="#std-templatefilter-date"><code class="xref std std-tfilter docutils literal notranslate"><span class="pre">date</span></code></a> filter instead (or along with <a class="reference internal" href="#std-templatefilter-time"><code class="xref std std-tfilter docutils literal notranslate"><span class="pre">time</span></code></a> if
you need to render a full <a class="reference external" href="https://docs.python.org/3/library/datetime.html#datetime.datetime" title="(in Python v3.14)"><code class="xref py py-class docutils literal notranslate"><span class="pre">datetime</span></code></a> value).</p>
<p>There is one exception the above rule: When passed a <code class="docutils literal notranslate"><span class="pre">datetime</span></code> value with
attached timezone information (a <a class="reference internal" href="../../topics/i18n/timezones.html#naive-vs-aware-datetimes"><span class="std std-ref">time-zone-aware</span></a> <code class="docutils literal notranslate"><span class="pre">datetime</span></code> instance) the <code class="docutils literal notranslate"><span class="pre">time</span></code> filter will

<p>When used without a format string, the <code class="docutils literal notranslate"><span class="pre">TIME_FORMAT</span></code> format specifier is
used:</p>

<p>It also supports domain-only links ending in one of the original top level

<p>Links can have trailing punctuation (periods, commas, close-parens) and leading

To enable it, set <a class="reference internal" href="../settings.html#std-setting-USE_I18N"><code class="xref std std-setting docutils literal notranslate"><span class="pre">USE_I18N</span></code></a> to <code class="docutils literal notranslate"><span class="pre">True</span></code>, then load it with

<p>To link to static files that are saved in <a class="reference internal" href="../settings.html#std-setting-STATIC_ROOT"><code class="xref std std-setting docutils literal notranslate"><span class="pre">STATIC_ROOT</span></code></a> Django ships
with a <a class="reference internal" href="#std-templatetag-static"><code class="xref std std-ttag docutils literal notranslate"><span class="pre">static</span></code></a> template tag. If the <a class="reference internal" href="../contrib/staticfiles.html#module-django.contrib.staticfiles" title="django.contrib.staticfiles: An app for handling static files."><code class="xref py py-mod docutils literal notranslate"><span class="pre">django.contrib.staticfiles</span></code></a>
app is installed, the tag will serve files using <code class="docutils literal notranslate"><span class="pre">url()</span></code> method of the

For example:</p>

<p>It is also able to consume standard context variables, e.g. assuming a

<p>If you’d like to retrieve a static URL without displaying it, you can use a
slightly different call:</p>
