python - Django 错误 admin.E033:用户名不是 users.CustomUser 的属性。为什么我的自定义用户管理员不起作用?
问题描述
我正在 Django 中创建自定义用户模型。我定义了一个自定义用户模型 (users.CustomUser),它是 AbstractBaseUser 的子类。我创建了一个自定义用户管理器(users.CustomUserManager),它是 BaseUserManager 的子类并且可以正常工作。我还创建了一个自定义用户管理员,它是 UserAdmin 的子类,因为我的 CustomUser 模型没有用户名字段(它使用“电子邮件”代替)。
据我所知,我已经正确编码了所有内容,但是当我运行“python manage.py makemigrations”时,我收到一条错误消息:
<class 'users.admin.CustomUserAdmin'>: (admin.E033) The value of 'ordering[0]' refers to 'username', which is not an attribute of 'users.CustomUser'.
我被困在这里。
我已经尝试过以下方法:(1)在我的自定义用户模型类中将用户名字段定义为电子邮件(2)尝试在我的自定义用户模型类和自定义用户管理员中将用户名设置为无(3)创建自定义用户注册和更改表单并用我的自定义用户管理员注册它们

('Company Information', {'fields': ('company',)}),
)
admin.site.register(CustomUser, CustomUserAdmin)
我希望能够正确迁移数据库并在我的站点上使用我的自定义用户模型(即允许用户注册并使用我列出的自定义字段创建配置文件)。相反,当尝试在命令提示符中运行迁移时,我得到了上面显示的错误。
任何帮助表示赞赏!谢谢!
解决方案
就像错误所说的那样,默认情况下,用户的管理类按用户名排序。由于您没有用户名,因此您应该覆盖它:
class CustomUserAdmin(BaseUserAdmin):
...
ordering = ('email',)
