Python Django 1.8 LookupError身份验证用户模型

我在我的应用程序中使用了一个名为

foll

的custon用户模型。 当我运行

syncdb

或

makemigrations

或

migrate

时，我会得到一个

LookupError

。请帮忙

在

settings.py

中，我将

AUTH\u USER\u MODEL

定义为

'foll.USER'

foll/models.py

我做错了什么？

在您的

User

类的

Meta

中，您设置了导致问题的

abstract=True

。删除它，然后运行

makemigrations

另外，请注意，您正在重复中已经存在的许多字段。你可以消除它们

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

    #The properties, methods, etc.. 

---

你运行过

manage.py migrate

？问得好，还有，别忘了

manage.py makemigrations

@Eva611是的。我还是一样error@nir谢谢我运行了这两个程序，得到了相同的

LookupError

。如果我尝试将它们添加到admin.py，我会得到一个

django.core.exceptions.impropertlyconfigured:模型用户是抽象的，因此无法向admin注册。

在您的

类Meta中

-您有

抽象=真

。删除它，然后运行makemigrations
