Class based generic view: ListView in Django 1.3
Category: /blog /djangoTags: django
Resources
Default naming
- default template called
<app name>/<model name>_list.html, 可以修改template_name来指定不同的文件 - default context variable is
object_list, 可以通过修改context_object_name来取更有意义的名字
演示代码
In urls.py
from django.conf.urls.defaults import *
from django.contrib.auth.decorators import login_required
from django.views.generic import DetailView, ListView
from polls.models import Poll
urlpatterns = patterns('',
(r'^$',
login_required(ListView.as_view(
queryset=Poll.objects.order_by('-pub_date')[:5],
context_object_name='latest_poll_list',
template_name='polls/index.html')),
)
)
in views.py, you can get parameters from URL, do filtering, and add to context to templates.
from django.contrib.auth.decorators import login_required
from django.utils.decorators import method_decorator
from django.views.generic import ListView
from books.models import Book
urlpatterns = patterns('',
(r'^books/(\w+)/$', PublisherBookListView.as_view()),
)
class AcmeBookListView(ListView):
context_object_name = "book_list"
template_name = "books/acme_list.html"
def get_queryset(self):
publisher = get_object_or_404(Publisher,
name__iexact=self.args[0])
return Book.objects.filter(publisher=publisher)
def get_context_data(self, **kwargs):
# Call the base implementation first to get a context
context = super(PublisherBookListView, self)
.get_context_data(**kwargs)
# Add in the publisher
context['publisher'] = self.publisher
return context
@method_decorator(login_required)
def dispatch(self, *args, **kwargs):
return super(ProtectedView, self).dispatch(*args, **kwargs)
