Pass url argument to ListView queryset

Question

models.py

class Lab(Model):
    acronym = CharField(max_length=10)

class Message(Model):
    lab = ForeignKey(Lab)

Answer 1

You need to write your own view for that and then just override the get_queryset method:

class CustomListView(ListView):
    def get_queryset(self):
        return Message.objects.filter(lab__acronym=self.kwargs['lab'])

and use CustomListView in urls also.
