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.
|
|
|
|
.. class:: django.views.generic.detail.DetailView
|
|
|
|
While this view is executing, ``self.object`` will contain the object that
|
|
the view is operating upon.
|
|
|
|

|
|
|
|
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 urls.py**::
|
|
|
|
from django.conf.urls import patterns, url
|
|
|
|
from article.views import ArticleDetailView
|
|
|
|
urlpatterns = patterns('',
|
|
url(r'^(?P<slug>[-_\w]+)/$', ArticleDetailView.as_view(), name='article-detail'),
|
|
)
|
|
|
|
.. 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.
