Django: Error Saving User With AbstractBaseUser and BaseUserManager

Question

I created a custom user model and am attempting to create a new user. I've tried manage.py createsuperuser from shell as well as User.objects.create_user(email, password) in my code. Both result in the same error:

$ ./manage.py createsuperuser
Email: person@example.com
Is manager: True
Password: 
Password (again): 
Traceback (most recent call last):

    return int(value)
ValueError: invalid literal for int() with base 10: 'person@example.com'

My model/manager:

class UserManager(BaseUserManager):
    def create_user(self, email, password, **kwargs):
        if not email:
            raise ValueError('Users must have an email address')

        user = self.model(self.normalize_email(email), **kwargs)
        user.set_password(password)
        user.save(using=self._db)
        return user

    def create_superuser(self, email, password, **kwargs):
        user = self.create_user(email, password, **kwargs)
        user.is_admin = True
        user.save(using=self._db)
        return user


class User(AbstractBaseUser, PermissionsMixin, EditMixin):
    email = models.EmailField(max_length=255, unique=True)
    business_access = models.ManyToManyField(BusinessAccess, blank=True)
    auth_key = models.UUIDField(unique=True, max_length=64, default=uuid.uuid4)
    is_manager = models.BooleanField(default=False)

    REQUIRED_FIELDS = ['is_manager']
    USERNAME_FIELD = 'email'
    objects = UserManager()

    class Meta:
        verbose_name = "User"
        verbose_name_plural = "Users"

    def __str__(self):
        return self.email

    def get_full_name(self):
        return self.email

    def get_short_name(self):
        return self.email

    @property
        def is_staff(self):
    return self.is_superuser

Am I doing something wrong?

Answer 1

Try this for the create_user method in the Manager

def _create_user(self, email, password,
                 is_staff, is_superuser, **extra_fields):
    """
    Creates and saves a User with the given email and password.
    """
    now = timezone.now()
    if not email:
        raise ValueError('The given email must be set')
    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

def create_user(self, email, password=None, **extra_fields):
    return self._create_user(email, password, False, False,
                             **extra_fields)

def create_superuser(self, email, password, **extra_fields):
    return self._create_user(email, password, True, True,
                             **extra_fields)

I tried your example and also ran into the same error. This is my implementation which works correctly without any problem

您需要写，这对我有帮助：

self.model(email=self.normalize_email(email), **kwargs)
