Return results from multiple models with Django REST Framework

by

It looks pretty close to me. I haven’t used ViewSets in DRF personally, but I think if you change your code to this you should get somewhere (sorry – not tested either of these):

class TimelineViewSet(viewsets.ModelViewSet):
    """
    API endpoint that lists all tweet/article objects in rev-chrono.
    """
    def list(self, request):
        queryset = list(itertools.chain(Tweet.objects.all(), Article.objects.all()))
        serializer = TimelineSerializer(queryset, many=True)
        return Response(serializer.data)

If you’re not wedded to using a ViewSet then a generics.ListAPIView would be a little simpler:

class TimeLineList(generics.ListAPIView):
    serializer_class = TimeLineSerializer

    def get_queryset(self):
        return list(itertools.chain(Tweet.objects.all(), Article.objects.all()))

Note you have to convert the output of chain to a list for this to work.
