我收到此错误是因为我创建了一个自定义用户模型，当完成所有设置后，将其设置为django / contrib / auth / models.py，我将电子邮件设置为USERNAME_FIELD，而REQUIRED_FIELD是某些字段，我的UserModel继承了AbstractBaseUser和PermissionMixin中定义的内容，我可以访问除“ Po User add section”之外的所有部分，并将代码放在models.py和admin.py以及settings.py，urls.py中，希望有人可以救命。非常感谢
错误痕迹：

父类（django.contrib.auth.admin.UserAdmin）具有包含add_fieldsets字段的username属性。在名为MyUserAdmin的add_fieldsets类中添加一个属性，并像fieldsets属性一样对待它：使用它来定义要在添加表单中显示的字段。
