Django 1.7, detailed view of the object is not displayed, I get a 404 error and the year is not specified, where to look?

Question

Django

Actually the question is in the title, then I enclose code listings:
settings.py

"""

        queryset = super(TalkListDetailView)
        queryset = queryset.filter(user=self.request.user)
        return queryset

Answer 1

No need to use generic.DateDetailView, searches by date, not by slug

Answer 2

And in a DB checked on presence of the necessary data? Maybe they don't really exist?
Or maybe you weren't logged in. Then filter(user=self.request.user) will return nothing. Or saved under the wrong user under which the authorization was.
