Filtering ListAPIView in django-rest-framework

问题:

I'm using ListAPIView, but I can't filter the results. My code is:

class UserPostReadView(generics.ListAPIView):
    serializer_class = PostSerializer
    model = serializer_class.Meta.model
    queryset = model.objects.order_by('-post_time')
    lookup_field = 'poster_id'
    paginate_by = 100

In this case, lookup_field is ignored, but the documentation says that it's supported for this class too. If I try to implement a custom get over a generic view, I don't know how to reimplement paginate_by. Any ideas?

I've found the solution

class UserPostsReadView(generics.ListAPIView):
    serializer_class = PostSerializer
    model = serializer_class.Meta.model
    paginate_by = 100
    def get_queryset(self):
        poster_id = self.kwargs['poster_id']
        queryset = self.model.objects.filter(poster_id=poster_id)
        return queryset.order_by('-post_time')

I know is late for this, but I wrote a little app that extends for ListAPIView and do this easier, check it out:
