好吧，我在名为accounts的应用程序中有一个自定义用户模型。 accounts.User看起来像这样：
from django.contrib.auth.models import AbstractBaseUser
from django.core.validators import RegexValidator
from django.db import models
from django.db.models.signals import post_save
from django.dispatch import receiver
from accounts.managers import UserManager
from base.models import Model
from accounts.models.profiles import Profile
class User(Model, AbstractBaseUser):
objects = UserManager()
phone_regex = RegexValidator(
regex=r'^\+?1?\d{9,15}$',
message="Phone number must be entered in the format: '+999999999'. 9-15 digits allowed.",
)
phone = models.CharField(
validators=[phone_regex],
max_length=17,
blank=True
)
email = models.EmailField(
max_length=255,
unique=True,
)
active = models.BooleanField(
default=True
)
staff = models.BooleanField(
default=False
)
superuser = models.BooleanField(
default=False
)
USERNAME_FIELD = 'email'
REQUIRED_FIELDS = []
def __str__(self):
return self.email
def has_perm(self, perm, obj=None):
return True
def has_module_perms(self, app_label):
return True
@property
def is_active(self):
return self.active
@property
def is_staff(self):
return self.staff
@property
def is_superuser(self):
return self.superuser
def serialize(self):
data = {
'id': self.id,
'email': self.email,
}
return data
@receiver(post_save, sender=User)
def create_profile(sender, instance, created, **kwargs):
if created:
Profile.objects.create(user=instance)
@receiver(post_save, sender=User)
def save_profile(sender, instance, **kwargs):
instance.profile.save()
并且UserManager看起来像这样：
from django.contrib.auth.models import BaseUserManager
class UserManager(BaseUserManager):
def create_user(self, email, password):
if not email:
raise ValueError('Users must have an email')
if not password:
raise ValueError('Users must have a password')
user = self.model(
email=self.normalize_email(email),
)
user.set_password(password)
user.save(using=self._db)
return user
def create_staffuser(self, email, password):
user = self.create_user(
email=email,
password=password,
)
user.staff = True
user.save(using=self._db)
return user
def create_superuser(self, email, password):
user = self.create_user(
email=email,
password=password,
)
user.staff = True
user.superuser = True
user.save(using=self._db)
return user
我的帐户应用注册如下：
...
INSTALLED_APPS = [
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
'base',
'accounts',
]
AUTH_USER_MODEL = 'accounts.User'
...
我运行python manage.py makemigrations和python manage.py migrate，所有内容都按预期顺利运行。当我开始python manage.py createsuperuser时会发生问题。它会提示按预期提供电子邮件输入，但在输入电子邮件并单击输入时会返回错误。

我正在尝试的是我尝试通过删除数据库并进行迁移来重现错误，我发现我的应用中没有按预期创建迁移文件，因为它应该具有我自定义的迁移文件用户在数据库中创建。以前有人有这个错误吗？你是怎么解决的？
答案 0 :(得分：1)
从AbstractBaseUser创建自定义用户模型时，您不需要将Model类添加为父级，只需离开AbstractBaseUser：
class User(AbstractBaseUser)
在此明确的迁移文件之后，重新运行makemigrations和migrate。
答案 1 :(得分：0)
通过在我的应用中手动重新创建migrations/文件夹解决了该问题。删除数据库和迁移文件时删除了该文件夹。该文件夹不会自动使用python manage.py makemigrations和python manage.py migrate重新创建。
答案 2 :(得分：0)
我在使用 AbstractUser 时遇到了同样的问题。创建这些菜单字段。然后添加到用户
id
password
last_login
is_superuser
username
email
first_name
last_name
is_staff
is_active
date_joined
