AttributeError：“UserManager”对象没有属性“create_superuser”

Question

我按照 Django 的方式设置了自定义用户管理器，但仍然收到属性错误。我不确定还有什么问题。

class UserManager(BaseUserManager):
    def create_user(self, email, date_of_birth, password=None):
        """
        Creates and saves a User with the given email, date of
        birth and password.
        """
        if not email:
            raise ValueError('Users must have an email address')

        user = self.model(
            email=self.normalize_email(email),
        )

        user.set_password(password)
        user.save(using=self._db)
        return user

    def create_superuser(self, email, date_of_birth, password):
        """
        Creates and saves a superuser with the given email, date of
        birth and password.
        """
        user = self.create_user(email,
            password=password,
            date_of_birth=date_of_birth
        )
        user.is_admin = True
        user.save(using=self._db)
        return user

class User(AbstractBaseUser):
    email = models.EmailField(
        verbose_name='email address',
        max_length=255,
        unique=True,
    )
    date_of_birth = models.DateField()
    is_active = models.BooleanField(default=True)
    is_admin = models.BooleanField(default=False)

    objects = UserManager()

    USERNAME_FIELD = 'email'

    def get_full_name(self):
        # The user is identified by their email address
        return self.email

    def get_short_name(self):
        # The user is identified by their email address
        return self.email

    def __str__(self):              # __unicode__ on Python 2
        return self.email

我已经定义了用户和超级用户。并将该对象设置为UserManager。

回溯是：

 AttributeError: 'UserManager' object has no attribute 'create_superuser'

我正在运行的代码是：

python manage.py createsuperuser

我猜你有 Django 1.8。以下是您创建自己的继承模型的模型所需要做的事情AbstractUser。

在你的模型中：

from django.contrib.auth.models import AbstractUser
from django.db import models

class User(AbstractUser):
  pass

您的User模型将自动继承 ofUserManager然后AbstractUser您不必编写 :objects = YourUserManager()除非您想扩展它。在这种情况下，您可以这样做：

from django.contrib.auth.models import AbstractUser, UserManager as AbstractUserManager
from django.db import models

class UserManager(AbstractUserManager):
  pass

class User(AbstractUser):
    objects = UserManager()

settings.py定义Django 应用程序中使用的用户模型：

# <module_name>.<user_model_name>
AUTH_USER_MODEL = 'user.User'

现在，当您想在其他应用程序中导入用户模型以使用它时，请使用settings.AUTH_USER_MODEL. 这是一个例子：

# <module_name>.<user_model_name>
AUTH_USER_MODEL = 'user.User'
