[Answered ]-Django is giving trouble on urls to catch and forward to a view. (slug fields)

Looking at your code:

def get_queryset(self):
    sculpture_slug = get_object_or_404(Sculpture, slug__iexact=self.kwargs['slug'])

Here you’re fetching the Sculpture object that matches the captured slug.

    return Sculpture.objects.filter(slug=sculpture_slug)

And then you get the Sculpture object whose slug is another Sculpture object. I wonder how this even works in some cases 🙂

Since you have a DetailView, you can directly use get_object():

class SculptureDetailView(DetailView):
    def get_object(self):
        return get_object_or_404(Sculpture, slug__iexact=self.kwargs['slug'])
