# Generic display views

The two following generic class-based views are designed to display data. On many projects they are typically the most commonly used views.

## `DetailView`

class django.views.generic.detail.DetailView

  While this view is executing, `self.object` will contain the object that the view is operating upon.

  Ancestors (MRO)

  This view inherits methods and attributes from the following views:

  - `django.views.generic.detail.SingleObjectTemplateResponseMixin`

  - `django.views.generic.base.TemplateResponseMixin`

  - `django.views.generic.detail.BaseDetailView`

  - `django.views.generic.detail.SingleObjectMixin`

  - `django.views.generic.base.View`

  Method Flowchart

  1. `setup()`

  2. `dispatch()`

  3. `http_method_not_allowed()`

  4. `get_template_names()`

  5. `get_slug_field()`

  6. `get_queryset()`

  7. `get_object()`

  8. `get_context_object_name()`

  9. `get_context_data()`

  10. `get()`

  11. `render_to_response()`

  Example myapp/views.py:

      from django.utils import timezone
      from django.views.generic.detail import DetailView

      from articles.models import Article

      class ArticleDetailView(DetailView):
          model = Article

          def get_context_data(self, **kwargs):
              context = super().get_context_data(**kwargs)
              context["now"] = timezone.now()
              return context

  Example myapp/urls.py:

      from django.urls import path

      from article.views import ArticleDetailView

      urlpatterns = [
          path("<slug:slug>/", ArticleDetailView.as_view(), name="article-detail"),
      ]

  Example myapp/article_detail.html:

      <h1>{{ object.headline }}</h1>
      <p>{{ object.content }}</p>
      <p>Reporter: {{ object.reporter }}</p>
      <p>Published: {{ object.pub_date|date }}</p>
      <p>Date: {{ now|date }}</p>

class django.views.generic.detail.BaseDetailView

  A base view for displaying a single object. It is not intended to be used directly, but rather as a parent class of the `django.views.generic.detail.DetailView` or other views representing details of a single object.

  Ancestors (MRO)

  This view inherits methods and attributes from the following views:

  - `django.views.generic.detail.SingleObjectMixin`

  - `django.views.generic.base.View`

  Methods

  get(request, *args, **kwargs)

    Adds `object` to the context.

## `ListView`

class django.views.generic.list.ListView

  A page representing a list of objects.

  While this view is executing, `self.object_list` will contain the list of objects (usually, but not necessarily a queryset) that the view is operating upon.

  Ancestors (MRO)

  This view inherits methods and attributes from the following views:

  - `django.views.generic.list.MultipleObjectTemplateResponseMixin`

  - `django.views.generic.base.TemplateResponseMixin`

  - `django.views.generic.list.BaseListView`

  - `django.views.generic.list.MultipleObjectMixin`

  - `django.views.generic.base.View`

  Method Flowchart

  1. `setup()`

  2. `dispatch()`

  3. `http_method_not_allowed()`

  4. `get_template_names()`

  5. `get_queryset()`

  6. `get_context_object_name()`

  7. `get_context_data()`

  8. `get()`

  9. `render_to_response()`

  Example views.py:

      from django.utils import timezone
      from django.views.generic.list import ListView

      from articles.models import Article

      class ArticleListView(ListView):
          model = Article
          paginate_by = 100  # if pagination is desired

          def get_context_data(self, **kwargs):
              context = super().get_context_data(**kwargs)
              context["now"] = timezone.now()
              return context

  Example myapp/urls.py:

      from django.urls import path

      from article.views import ArticleListView

      urlpatterns = [
          path("", ArticleListView.as_view(), name="article-list"),
      ]

  Example myapp/article_list.html:

      <h1>Articles</h1>
      <ul>
      {% for article in object_list %}
          <li>{{ article.pub_date|date }} - {{ article.headline }}</li>
      {% empty %}
          <li>No articles yet.</li>
      {% endfor %}
      </ul>

  If you’re using pagination, you can adapt the example template from the pagination docs.

class django.views.generic.list.BaseListView

  A base view for displaying a list of objects. It is not intended to be used directly, but rather as a parent class of the `django.views.generic.list.ListView` or other views representing lists of objects.

  Ancestors (MRO)

  This view inherits methods and attributes from the following views:

  - `django.views.generic.list.MultipleObjectMixin`

  - `django.views.generic.base.View`

  Methods

  get(request, *args, **kwargs)

    Adds `object_list` to the context. If `allow_empty` is True then display an empty list. If `allow_empty` is False then raise a 404 error.
