用户管理器对象没有属性 create_superuser

Question

问题：使用 manage.py 时，我无法创建超级用户，并且它以错误响应 AttributeError: 'UserManager' object has no attribute 'create_superuser’。然后我尝试手动导入所有必要的模型并在 python shell 中运行它，但遇到了相同的障碍。

目标：使用继承的基本管理类正确创建超级用户

代码：

from django.contrib.auth.models import AbstractUser, BaseUserManager, Group

class UserManager(BaseUserManager):
    def get_by_natural_key(self, username):
        return self.get(username__iexact=username)

class User(AbstractUser):
    objects = UserManager()

    …
    …

    def __str__(self):
         return ’{}’.format(self.id)

    def save(self, *args, **kwargs):
        self.full_clean()
        super(FollowUser, self).save(*args, **kwargs)

BaseUserManager没有任何称为 的方法create_superuser。您需要像这样将它添加到 Manager 类（从github复制粘贴）：

class UserManager(BaseUserManager):
    def _create_user(self, username, email, password, **extra_fields):
        """
        Create and save a user with the given username, email, and password.
        """
        if not username:
            raise ValueError('The given username must be set')
        email = self.normalize_email(email)
        username = self.model.normalize_username(username)
        user = self.model(username=username, email=email, **extra_fields)
        user.set_password(password)
        user.save(using=self._db)
        return user

    def create_superuser(self, username, email, password, **extra_fields):
        extra_fields.setdefault('is_staff', True)
        extra_fields.setdefault('is_superuser', True)

        if extra_fields.get('is_staff') is not True:
            raise ValueError('Superuser must have is_staff=True.')
        if extra_fields.get('is_superuser') is not True:
            raise ValueError('Superuser must have is_superuser=True.')

        return self._create_user(username, email, password, **extra_fields)

或者，您可以从UserManager类中继承您的 Manager 。
