How can return response without queryset in Django REST Framwork views

Question

I am using django rest framework for serialize the data, I came across a scenario where i have to return two different queryset result in on view, so i tried in this way but failed to get response

q1 = tbl_nt.objects.values_list('id', 'value', 'geometry')

q2 = tbl_network.objects.values_list('id', 'value', 'geometry')

Tried following methods for build queryset

queryset = (q1) | (q2)

queryset = list(q1) + list(q2)

queryset = chain(q1, q2)

queryset = list(chain(q1, q2))

One solution that comes in my mind get the union of both queryset, serialize them and send in response so i write down this code for view just testing

class SnippetList(APIView):

    def get(self, request, format=None):
        snippets = tbl_network.objects.all()
        json = serializers.serialize('json', snippets)
        return Response(json)

Now this exception is facing

'Cannot apply DjangoModelPermissions on a view that does not have .model or .queryset property.'

My strategy is simple i want to create list, serialize the list and send in response

So my question is how to pass response without queryset? I this approach is correct?

I have also posted question related to this problem where one solution is posted implement inheritance but i don't want to change Database table structure

django combine queries on two different base models
