我是 Django 初学者，学习如何在我的帐户应用程序中使用 Abstractuser 创建自定义用户模型。 但是在创建注册系统时我遇到了这个问题： django.db.utils.OperationalError：没有这样的表：auth_user

My accounts/views.py 's register view:

用户模型（accounts/models.py）：
from django.contrib.auth.models import AbstractUser
from django.db import models
from django.utils.translation import gettext as _
from .managers import UserManager
class User(AbstractUser):
username = None
email = models.EmailField(_('email address'), unique=True)
USERNAME_FIELD = 'email'
REQUIRED_FIELDS = []
objects = UserManager()
def __str__(self):
return f'User({self.id}, "{self.email}")'
账户/managers.py
from django.contrib.auth.base_user import BaseUserManager
from django.utils.translation import gettext as _
class UserManager(BaseUserManager):

use_in_migration = True
def create_user(self, email, password, **extra_fields):
if not email:
raise ValueError(_('Users must have an email'))
email = self.normalize_email(email)
user = self.model(email=email, **extra_fields)
user.set_password(password)
user.save()
return user
def create_superuser(self, email, password, **extra_fields):
extra_fields.setdefault('is_staff', True)
extra_fields.setdefault('is_superuser', True)
extra_fields.setdefault('is_active', 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, password, **extra_fields)
我尝试过的：
当我尝试使用 createsuperuser、django Admin 和 django shell 创建用户时；它工作完美，没有任何错误。 只有当我在寄存器视图中调用 save() 时才会出现错误。
您是否在settings.py中指定了新用户？ " AUTH_USER_MODEL = '账户.用户' "
