TypeError: User() 在使用 CustomUser 时得到了一个意外的关键字参数“is_staff”

Question

我正在使用 AbstractBaseUser 创建自定义用户，但每当我尝试创建超级用户时，它都会显示

TypeError: User() got an unexpected keyword argument 'is_staff'
user=self._create_user(email, password, True, True, **extra_fields)
  File "C:\Users\user1\django\customuserproject\users\models.py", line 24, in _create_user

我该如何解决这个问题？我已经检查了有关此问题的其他 StackOverflow 帖子，但它们没有帮助我。我还没有尝试过使用普通用户（我需要一个超级用户来创建普通用户），但我相信它会是一样的

我的models.py：

class UserManager(BaseUserManager):
    def _create_user(self, email, password, is_staff, is_superuser, **extra_fields):
        if not email:
            raise ValueError('Users must have an email address')
        now = timezone.now()
        email = self.normalize_email(email)
        user = self.model(
            email=email,            
            is_staff=is_staff, 
            is_active=True,
            is_superuser=is_superuser, 
            last_login=now,
            date_joined=now, 
            **extra_fields
        )
        #user.set_password(password)
        user.save(using=self._db)
        return user

Answer 1

尝试将getter 和setters 与@property 一起使用，它们的工作效果会更好，并且可以清楚地实现。

class Demo:
    def __init__(self):
        self._age = 0

    # using property decorator
    # a getter function
    @property
    def age(self):
        print("getter method called")
        return self._age

    # a setter function
    @age.setter
    def age(self, a):
        if(a < 18):
            raise ValueError("Sorry you age is below eligibility criteria")
        print("setter method called")
        self._age = a

感谢@Iain Shelvington、@Willem Van Onsem 和 @7u5h4r。

我通过删除我声明的所有属性解决了这个问题，只保留了变量：is_staff、is_superuser、is_active。 p>
