Django Rest Framework - 在 u'None' 中查找键 [form] 失败

Question

我最近将 Django Rest Framework 更新到了 3.3.1 版。这样做后，我收到以下错误：Failed lookup for key [form] in u'None'

当我访问这个视图时它就来了：

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

有人知道这是什么问题吗？

谢谢！

Answer 1

在filter_backends 中，我只需要删除filters.DjangoFilterBackend。现在可以正常使用了。
