from django.conf.urls import patterns, url 
from django.views.generic import DetailView, ListView 
from polls.models import Poll 

urlpatterns = patterns('', 
    url(r'^$', 
     ListView.as_view(
      queryset=Poll.objects.order_by('-pub_date')[:5], 
      context_object_name='latest_poll_list', 
      template_name='polls/index.html'), 
     name='index'), 
    url(r'^(?P<pk>\d+)/$', 
     DetailView.as_view(
      model=Poll, 
      template_name='polls/detail.html'), 
     name='detail'), 
    url(r'^(?P<pk>\d+)/results/$', 
     DetailView.as_view(
      model=Poll, 
      template_name='polls/results.html'), 
     name='results'), 
    url(r'^(?P<poll_id>\d+)/vote/$', 'polls.views.vote', name='vote'), 
) 

anketler/templates/anketler/detail.html. Sadece bir adımı kaçırdım.

url(r'^polls/', include('polls.urls')), 

için: Sadece bir satır değişti

urlpatterns = patterns('', 
    # Examples: 
    # url(r'^$', 'hello.views.home', name='home'), 
    # url(r'^hello/', include('hello.foo.urls')), 

    # Uncomment the admin/doc line below to enable admin documentation: 
    # url(r'^admin/doc/', include('django.contrib.admindocs.urls')), 

    # Uncomment the next line to enable the admin: 
    url(r'^polls/', include('polls.urls', namespace="polls")), 
    url(r'^admin/', include(admin.site.urls)), 
) 

Ve şimdi çalışıyor: sitede/urls.py günü

url(r'^polls/', include('polls.urls', namespace="polls")), 

, şimdi diyor.
