Question

抱歉，我是第一次集成drf-yasq摇摇杆！如果我的问题很愚蠢。我从这里https://drf-yasg.readthedocs.io/en/stable/readme.html阅读了文档，并按照说明进行操作，最后得到了AttributeError: 'Response' object has no attribute 'label'。原始代码来自https://drf-yasg.readthedocs.io/en/stable/readme.html。请帮助我缺少的地方：

花了我几个小时的代码，我终于使它工作了。 drf-yasg在覆盖get_queryset()和get_serializer()之类的功能并使用self.request.user筛选出已认证用户的数据时无法正常工作，请使用以下编码技术来解决此问题：

def get_queryset(self):
    if getattr(self, 'swagger_fake_view', False):
        return MyModel.objects.none()  # return empty queryset
    return self.queryset.filter(user=self.request.user)
