PAGE NOT FOUND: No title found matching the query.
In fact, you don't have to override get_object method, what you need to do is just to define a proper slug field(not pk_url_kwarg) like this:
class TitleDetail(DetailView):
model = Title
slug_field = "emp_no"
slug_url_kwarg = "emp_no"
And here is the source code if you'd like to see what has happened behind.
You can override the get_object() method to do whatever you want:
def get_object(self, queryset=None):
queryset = self.get_queryset() if queryset is None else queryset
return get_object_or_404(queryset, emp_no_id=self.kwargs['emp_no'])
In case you haven't seen it before, see the get_object_or_404() documentation.
