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:

Method Flowchart

  1. dispatch()
  2. http_method_not_allowed()
  3. get_template_names()
  4. get_slug_field()
  5. get_queryset()
  6. get_object()
  7. get_context_object_name()
  8. get_context_data()
  9. get()
  10. render_to_response()

Example myapp/views.py:

from django.views.generic.detail import DetailView
from django.utils import timezone
from articles.models import Article
class ArticleDetailView(DetailView):
    model = Article
    def get_context_data(self, **kwargs):
        context = super(ArticleDetailView, self).get_context_data(**kwargs)
        context['now'] = timezone.now()
        return context

Example myapp/urls.py:

from django.conf.urls import url
from article.views import ArticleDetailView
urlpatterns = [
    url(r'^(?P<slug>[-\w]+)/$', 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>

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:

Method Flowchart

  1. dispatch()
  2. http_method_not_allowed()
  3. get_template_names()
  4. get_queryset()
  5. get_context_object_name()
  6. get_context_data()
  7. get()
  8. render_to_response()

Example views.py:

from django.views.generic.list import ListView
from django.utils import timezone
from articles.models import Article
class ArticleListView(ListView):
    model = Article
    def get_context_data(self, **kwargs):
        context = super(ArticleListView, self).get_context_data(**kwargs)
        context['now'] = timezone.now()
        return context

Example myapp/urls.py:

from django.conf.urls import url
from article.views import ArticleListView
urlpatterns = [
    url(r'^$', 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>
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:

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.
