django - 为PoUser指定的Django未知字段(用户名)

Question

我收到此错误是因为我创建了一个自定义用户模型，并且在完成所有设置后(将其设置为django / contrib / auth / models.py)，我将电子邮件设置为USERNAME_FIELD，而REQUIRED_FIELD是未在其中定义的某些字段我的UserModel继承了AbstractBaseUser和PermissionMixin，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，希望有人能提供帮助。非常感谢

错误痕迹:

Answer 1

父类(django.contrib.auth.admin.UserAdmin)具有add_fieldsets属性，其中包括username字段。在您的MyUserAdmin类中添加一个名为add_fieldsets的属性，并将其像fieldsets属性一样对待:使用该属性定义要在添加表单中显示的字段。

注意:如果将username设置为email，则将email添加到add_fieldsets。

请参阅"Customizing authentication in Django" docs page和the full example from the Django docs上有关add_fieldset的注释。
