python - manage.py createsuperuser 不适用于自定义用户模型

Question

我正在使用 Django，并且我创建了一个自定义用户模型，以便能够使用电子邮件作为主要登录方法而不是用户名。一切正常，但我无法使用命令创建 super 用户 python manage.py createsuperuser.

这是我的代码:

models.py

from django.db import models
from django.core.mail import send_mail
from django.contrib.auth.models import PermissionsMixin
from django.contrib.auth.base_user import AbstractBaseUser
from django.db.models import CASCADE
from django.utils.translation import ugettext_lazy as _
from .managers import UserManager

    class User(AbstractBaseUser, PermissionsMixin):
        user_name = models.CharField(_('user name'), max_length=35)
        email = models.EmailField(_('email address'), unique=True)
        date_joined = models.DateTimeField(_('date joined'), auto_now_add=True)
        is_active = models.BooleanField(_('active'), default=True)
        is_staff = models.BooleanField(_('staff'), default=False)
        is_superuser = models.BooleanField(_('superuser'), default=False)
        avatar = models.ImageField(upload_to='media/', null=True, blank=True)

        objects = UserManager()


        USERNAME_FIELD = 'email'
        REQUIRED_FIELDS = []


        class Meta:
            verbose_name = _('user')
            verbose_name_plural = _('users')

        def email_user(self, subject, message, from_email=None, **kwargs):
            '''
            Sends an email to this User.
            '''
            send_mail(subject, message, from_email, [self.email], **kwargs)

这里是ma​​nagers.py

from django.contrib.auth.base_user import BaseUserManager

    class UserManager(BaseUserManager):
        use_in_migrations = True

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

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

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

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

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

该进程创建一个普通用户而不是 super 用户，并且它被创建。但我无法登录管理面板 /admin

您可以像下面这样实现 UserManager。它比您的代码更简单。

class UserManager(BaseUserManager):

    def create_user(self, email, password=None):

        if email is None:
            raise TypeError('Users must have an email address.')

        user = self.model(email=self.normalize_email(email))
        user.set_password(password)
        user.save()

        return user

    def create_superuser(self, email, password):

        if password is None:
            raise TypeError('Superusers must have a password.')

        user = self.create_user(email, password)
        user.is_superuser = True
        user.is_staff = True
        user.save()

        return user
