我正在django中创建一个简单的web应用程序，其中用户通过电子邮件而不是用户名来识别。我一直在遵循指南：https://www.fomfus.com/articles/how-to-use-email-as-username-for-django-authentication-removing-the-username/
而且效果很好
然而，如果我选择另外两个必填字段，则超级用户的创建将失败，而普通用户的创建则不会失败。有人能帮我理解为什么吗？
用户应用程序-型号.py
from django.contrib.auth.models import AbstractUser, BaseUserManager
from django.db import models
from django.utils.translation import ugettext_lazy as _
class UserManager(BaseUserManager):
"""Define a model manager for User model with no username field."""
use_in_migrations = True
def _create_user(self, email, first_name, last_name, password, **extra_fields):
"""Create and save 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 = self.model(first_name=first_name, **extra_fields)
user = self.model(last_name=last_name, **extra_fields)
user.set_password(password)
user.save(using=self._db)
return user
def create_user(self, email, first_name, last_name, password=None, **extra_fields):
"""Create and save a regular User with the given email and password."""
extra_fields.setdefault('is_staff', False)
extra_fields.setdefault('is_superuser', False)
return self._create_user(email, first_name, last_name, password, **extra_fields)
def create_superuser(self, email, first_name, last_name, password, **extra_fields):
"""Create and save a SuperUser with the given email and password."""
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(email, first_name, last_name, password, **extra_fields)
class User(AbstractUser):
"""User model."""
username = None
email = models.EmailField(_('email address'), unique=True)
first_name = models.CharField(verbose_name='First Name', max_length = 255, unique=False)
last_name = models.CharField(verbose_name='Last Name', max_length = 255, unique=False)
USERNAME_FIELD = 'email'
REQUIRED_FIELDS = ['first_name','last_name']
objects = UserManager()
显然，在发布问题之前的几个小时里，我试图了解发生了什么，自然地，我在发布后稍微找到了答案。
user = self.model(email=email, **extra_fields)
user = self.model(first_name=first_name, **extra_fields)
user = self.model(last_name=last_name, **extra_fields)
是_create_user()中错误的触发器
正确的代码应该是：
user = self.model(email=email, first_name=first_name, last_name=last_name, **extra_fields)
