Python Django&；运行'；makemigrations'；

我是python的大三学生，我想使用django创建一个Web服务，我编写了model.py，我的类中似乎有问题，但我无法修复。 我不知道错误是在“相关名称”中还是在模型中

运行命令“makemigrations”后的错误消息为：

ERRORS:
PSTL.User.groups: (fields.E304) Reverse accessor for 'User.groups' clashes with reverse accessor for 'User.groups'.

    HINT: Add or change a related_name argument to the definition for 'User.groups' or 'User.groups'.

我的model.py是：

已经有一个名为User的内置类，如果要向其添加额外字段，最好按照此处所述创建一对一关系。您是否忘记将

AUTH\u User\u MODEL

设置设置为自定义用户模型？您需要将其设置为

“PSTL.User”

，以便Django知道如何使用您的用户模型，而不是默认模型。
