Django-rest-framework nested urls with drf-nested-routers

@Artem, I use a very similar solution in my code. Here is what I did:

I have an entity called Institutions. I created a route for it, like this:

router.register(r'institutions', SecurityViews.InstitutionViewSet, base_name='institutions')

My URLS look like this:

http://127.0.0.1:8000/v1/institutions/
http://127.0.0.1:8000/v1/institutions/1/

The first URL lists all institutions, the second, is the details URL.

Now, I have people whom I want to be members of those institutions. So, for the route, on urls.py, I did this:

institutions_router = routers.NestedSimpleRouter(router, r'institutions', lookup='institution')

institutions_router.register(r'members', SecurityViews.InstitutionMemberViewSet, base_name='institution-members')

Now, I can get the members of a particular institution with the following URL:

http://127.0.0.1:8000/v1/institutions/1/members/

I also had to define the relationships, mapping the pk of the main entity to the child entity, via serializer. I wont post the whole code here, as I imagine you are familiar with the concept.

For me, the solution proposed by @Artem solved the one problem I had: returning a filtered query. It is working fine now.

I hope this will help you.

No need to override all actions, you can just override the "get_queryset()"

class NameserverViewSet(viewsets.ViewSet):
    queryset = Nameserver.objects.all()

    def get_queryset(self):
        if self.kwargs.get('domain_pk'):
            return Nameserver.objects.filter(domain=domain_pk)
        else:
            return super(NameserverViewSet, self).get_queryset()

Solution came from Alan, the author.

Here is how ViewSet should be implemented:

class NameserverViewSet(viewsets.ViewSet):
    queryset = Nameserver.objects.all()

    def list(self, request, domain_pk=None):
        queryset = self.queryset.filter(domain=domain_pk)
        serializer = NameserverSerializer(queryset, many=True)
        return Response(serializer.data)

    def retrieve(self, request, pk=None, domain_pk=None):
        queryset = self.queryset.get(pk=pk, domain=domain_pk)
        serializer = NameserverSerializer(queryset)
        return Response(serializer.data)
