我在我的应用程序中使用了一个托管用户模型，名为 fowl 。
当我运行 syncdb 或 makemigrations 或迁移我得到一个 LookupError 。请帮助

I'm using a custon user model as such in my app called fowl.When I run syncdb or makemigrations or migrate I get a LookupError. Please help

在 settings.py 中我已经定义了 AUTH_USER_MODEL 作为'fowl.User'

In settings.py I have defined AUTH_USER_MODEL as 'fowl.User'

我做错了什么？

推荐答案

在您的用户类' Meta 中，您已设置 abstract = True 导致问题。删除它，然后运行 makemigrations 。

In your User class' Meta, you have set the abstract=True which is causing the issue. Remove it and then run makemigrations.

另外，请注意，您正在重复已经存在于。你可以消除它们。

Also, note that you are repeating many fields already present in AbstractUser class. You may eliminate them.

class User(AbstractBaseUser, PermissionsMixin):
    is_admin = models.BooleanField(default=False)
    is_festival = models.BooleanField(default=True)

    #The properties, methods, etc..
