扩展django用户django-rest_框架会给我带来KeyError

我是django rest_框架的新手，已经发布了，我已经根据django文档扩展了auth_用户，但是这给我带来了困难

型号.py

    user = models.OneToOneField(User, primary_key=True, on_delete=models.CASCADE)

我知道这是一个新手问题，但是，我真的需要帮助

提前感谢。

您以错误的方式获取配置文件数据。 validated_data是用户和配置文件数据的字典，您将分别保存这些数据

像这样拿

profile_data = validated_data.pop('userprofile')

请注意，我们弹出了userprofile数据，因此现在您只在验证的\u数据中保留了用户数据。所以一个完整的流程如下所示

profile_data = validated_data.pop('userprofile')
user = User.objects.create(**validated_data)
UserProfile.objects.create(user=user, **profile_data)
return user

看看这里

因为，这不是一个完全嵌套的模型（银行账户是嵌套的），所以当我这样做时：

profile_data = validated_data.pop('userprofile')
user = User.objects.create(**validated_data)
UserProfile.objects.create(user=user, **userprofile)
return user

把我扔了
