Django Rest框架 - 在u'None'

Question

我最近将Django Rest Framework更新到版本3.3.1。在我这样做之后，我收到以下错误：Failed lookup for key [form] in u'None'

当我访问此视图时，它即将到来：

class SearchListAPIView(generics.ListAPIView):
    serializer_class = SearchMyUserSerializer
    filter_backends = (
        filters.DjangoFilterBackend,
        filters.SearchFilter,
        filters.OrderingFilter,
    )
    search_fields = ('^username', '^full_name',)

    def get_queryset(self):
        queryset = MyUser.objects.all()
        username = self.request.query_params.get('username', None)
        full_name = self.request.query_params.get('full_name', None)

        if username and full_name is not None:
            queryset = queryset.filter(username=username, full_name=full_name)
        elif username is not None:
            queryset = queryset.filter(username=username)
        elif full_name is not None:
            queryset = queryset.filter(full_name=full_name)
        return queryset

有谁知道这里的问题是什么？

谢谢！

Answer 1

在filter_backends中，我只需删除filters.DjangoFilterBackend。现在工作正常。
