AttributeError：'UserManager'对象没有属性'create_superuser' [英] AttributeError: 'UserManager' object has no attribute 'create_superuser'

问题描述

我已经按照Django的方式设置了我的customUser管理器，我仍然收到属性错误。我不知道还有什么可以错的。

I have my customUser manager setup in this way per Django and I am still getting the attribute error. I'm not sure what else can be wrong.

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。并将对象设置为UserManager。

I have defined the user and the superuser. And set the object to UserManager.

追溯是：

我正在运行的代码是：

python manage.py createsuperuser

推荐答案

我假设你有Django 1.8。以下是创建您继承 AbstractUser 模型的自己的模型。

I supposed that you have Django 1.8. Here is what you have to do to create your own models which inherit of AbstractUser model.

在您的模型中：

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

class User(AbstractUser):
  pass

您的用户模型将自动继承 UserManager AbstractUser ，那么你不必写： objects = YourUserManager（）除非你想扩展它。在这种情况下，您可以执行以下操作：

Your User model will automatically inherit of the UserManager of AbstractUser then you don't have to write : objects = YourUserManager() unless you want to extend it. In this case, you can do this :

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

class UserManager(AbstractUserManager):
  pass

class User(AbstractUser):
    objects = UserManager()

在 settings.py 用于您的Django应用程序：

Define the User model in settings.py used in your Django apps :

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

现在，当您要导入用户模型在其他应用程序中使用它，使用 settings.AUTH_USER_MODEL 。这里是一个例子：

Now, when you want to import your user model in an other app to use it, use settings.AUTH_USER_MODEL. here is an example :

from django.db import models
from django.conf import settings

class Token(models.Model):
    user = models.ForeignKey(settings.AUTH_USER_MODEL)

阅读正确的Django文档以获取更多信息：扩展现有用户模型
