从视图集object python django返回不同的对象

我有以下视图集

我有以下型号NoteRequest和NoteInfo

class NoteRequestViewSet(viewsets.ModelViewSet):

    queryset = NoteInfo.objects.all()

    serializer_class = NoteInfoSerializer

    pagination_class = None
    print(queryset)
    print(serializer_class)

    def list(self, request):
       try:
            obj = self.get_queryset().get(
                Q(refno=pk) | Q(client_id=pk)
            )
            serializer = self.get_serializer(obj)
            return Response(serializer.data)

        except Exception as e:
            return Response(str(e))

我希望能够返回NoteInfo的序列化对象,而不是NoteRequest,但不确定如何返回。

谢谢
