Serializer.is_valid()始终返回False。 Serializer.errors为空

我正在尝试通过POSTMAN向我的API发送一些图像。 但是,一直以来我都在获取206 status,如果serializer.is_valid()不是True,则会返回该值。此外,serializer.errors对于每个请求都是空的。 在添加图像字段之前,它工作正常。 MEDIA_ROOTMEDIA_URL字段已经创建。

使用Django的管理页面效果很好。

我正在使用POSTMAN发送请求。 我得到的回应:

{
    "data": {}
}

否,序列化程序无效。这项测试:

if serializer.is_valid() in request.data:

检查请求数据中是否为True(或False),而不是。删除in

if serializer.is_valid():

(另外,请注意,未使用您的queryset和parser_classes变量。看起来您已从基于类的视图复制了这些变量,在此函数视图中不需要它们。)
