你好我试图制作django自定义用户模型，但是我收到以下错误。 -
错误：
auth.User.groups：（fields.E304）'User.groups'的反向访问者 与'Freelancer.groups'的反向访问者发生冲突。 提示：在“User.groups”或“Freelancer.groups”的定义中添加或更改related_name参数。 auth.User.user_permissions： （fields.E304）“User.user_permissions”冲突的反向访问器 使用'Freelancer.user_permissions'的反向访问器。 提示：将“related_name”参数添加或更改为“User.user_permissions”或“Freelancer.user_permissions”的定义。 login.Freelancer.groups：（fields.E304）反向访问器 'Freelancer.groups'与'User.groups'的反向访问者冲突。 提示：在“Freelancer.groups”或“User.groups”的定义中添加或更改related_name参数。 login.Freelancer.groups： （fields.E331）字段通过模型指定多对多关系 'login.Freelancer_groups'，尚未安装。 login.Freelancer.user_permissions :( fields.E304）反向访问器 'Freelancer.user_permissions'与反向访问者冲突 'User.user_permissions'。 提示：在“Freelancer.user_permissions”或“User.user_permissions”的定义中添加或更改related_name参数。 login.Freelancer.user_permissions：（fields.E331）字段指定a 通过模型的多对多关系 'login.Freelancer_user_permissions'，尚未安装。

答案 0 :(得分：2)
您需要将AUTH_USER_MODEL设置设置为指向Freelancer类，因此Django知道不加载默认的用户模型。
对于Freelancer而言，向用户提供OneToOne也没有意义;它是该模型的替换。

从您的整个代码中删除以下行
from django.contrib.auth.models import User
并尝试导入自定义用户模型
