I think I know what the problem is with the Django 1.5 tutorial.
https://docs.djangoproject.com/en/1.5/intro/tutorial04/#amend-views
Both these classes are missing the "context_object_name" thingy, which
links to the templates.
class DetailView(generic.DetailView):
class ResultsView(generic.DetailView):
model = Birdy
template_name = 'polls/detail.html'
template_name = 'polls/results.html'
* context_object_name = 'poll'*
Now my Poll application is working without having to use Poll as Model.
Also it's now working using the "Generic views".
[ Problem solved... ]
