问题详情：
\1. auth.User.groups 和 auth.User.user_permissions 与 webapp.Suser 的冲突
Django 的内置 User 模型已经定义了 groups 和 user_permissions 字段，这些字段与 Group 和 Permission 模型有反向关系。当您在自定义用户模型 Suser 中继承 AbstractBaseUser 和 PermissionsMixin 时，也会有类似的字段和反向关系，这就导致了冲突。‘’
解决办法：
from django.contrib.auth.models import AbstractBaseUser, PermissionsMixin, BaseUserManagerclass Suser(AbstractBaseUser, PermissionsMixin):email = models.EmailField(verbose_name='邮箱', max_length=255, unique=True)username = models.CharField(max_length=50, verbose_name='用户名')is_active = models.BooleanField(default=True, verbose_name='激活用户')is_staff = models.BooleanField(default=False, verbose_name='职员状态')# 其他字段...groups = models.ManyToManyField('auth.Group',related_name='suser_groups', # 添加 related_name 以避免冲突verbose_name='groups',blank=True,help_text='The groups this user belongs to. A user will get all permissions granted to each of their groups.',related_query_name='suser',)user_permissions = models.ManyToManyField('auth.Permission',related_name='suser_permissions', # 添加 related_name 以避免冲突verbose_name='user permissions',blank=True,help_text='Specific permissions for this user.',related_query_name='suser',)
