r'^(?P<pk>\d+)$ URL 404ing - django

Question

I'm trying to use this link <a href="Annotation/{{ vod.id }}"> to load another page in my website base on primary key of videos. My url file is as follows:
urlpatterns = [
url(r'^$', ListView.as_view(queryset=Vod.objects.all().order_by("-date")[:25], template_name="Annotation/home.html")),
url(r'^(?P<pk>\d+)$', ListView.as_view(queryset=Vod.objects.get(pk=1).posts.all().order_by("-date"), template_name="Annotation/post.html")),
]
I get the standard 404 from the links generated using the aforementioned link.
Thanks!
edit: Added the base URLs
url(r'^admin/', admin.site.urls),
url(r'^Annotation', include('Annotation.urls')),
url(r'^Profile', include('Profile.urls')),
This is the URL for Profile.urls
url(r'^$', views.index, name='index'),
edit2: Changed URL and added view I'm trying to use.
url(r'^(?P<key>[0-9]+)$', views.post, name="post")
Here's views.post
def post(request, key):
try:
target_vod = Vod.objects.get(pk=key)
except Target.DoesNotExist:
raise Http404("Vod does not exist")
target_posts = Vod.objects.get(pk=key).posts.all().order_by("-date")
context = {'target_vod': target_vod, 'target_posts': target_posts}
return render(request, 'Annotation/post.html', context)

Answer 1

I have seperated the code and put it into a views.py. This should work.
urls.py
url(r'^(?P<pk>[0-9]+)$', AnnoList.as_view(), template_name="Annotation/post.html")),
Then in views.py:
class AnnoList(ListView):
template_name = 'Annotation/post.html'
def get_queryset(self):
self.vod = get_object_or_404(Vod, pk=self.args[0])
return Posts.objects.filter(vod=self.vod).all().order_by("-date")
I assuming here that you have two different tables and that Posts has a foreign key to Vod.
