问题描述
在尝试将现有项目升级到 Django 3.2（从 2.2）时，我收到以下错误：
...
from .permissionmodels import * # nopyflakes
File "/home/user/miniconda3/envs/app-web-py38-test/lib/python3.8/site-packages/cms/models/
permissionmodels.py",line 19,in <module>
User = apps.get_registered_model(user_app_name,user_model_name)
File "/home/user/miniconda3/envs/app-web-py38-test/lib/python3.8/site-packages/django/apps
/registry.py",line 273,in get_registered_model
raise LookupError(
LookupError: Model 'user_accounts.CustomUser' not registered.
自定义模型位于 apps/user_accounts/models.py 中，如下所示
from django.db import models
from django.contrib.auth.models import AbstractUser
from django.db import models
from .managers import CustomUserManager
class CustomUser(AbstractUser,PermissionsMixin):
username = None
email = models.EmailField(('email address'),unique=True)
# add additional fields in here
profile_picture = models.ImageField(upload_to='profile/',blank=True)
USERNAME_FIELD = 'email'
required_FIELDS = []
objects = CustomUserManager()
def __str__(self):
return self.email
安装的应用如下
INSTALLED_APPS = [
# this app is at the top because it defines a custom user model for the whole project
'apps.user_accounts','djangocms_admin_style','django.contrib.admin','django.contrib.auth','django.contrib.contenttypes',#'django.contrib.contenttypes.models.ContentType','django.contrib.sessions','django.contrib.messages','django.contrib.staticfiles','django.contrib.sitemaps',#after project creation#

AUTH_USER_MODEL = 'user_accounts.CustomUser'
感谢您提供有关修复或故障排除的任何帮助。
编辑：
apps/user_accounts/managers.py
from django.contrib.auth.base_user import BaseUserManager
from django.utils.translation import ugettext_lazy as _
class CustomUserManager(BaseUserManager):
"""
Custom user model manager where email is the unique identifiers
for authentication instead of usernames.
"""
def create_user(self,email,password,**extra_fields):
"""

"""
if not email:
raise ValueError(_('The Email must be set'))
email = self.normalize_email(email)
user = self.model(email=email,**extra_fields)
user.set_password(password)
user.save()
return user
def create_superuser(self,**extra_fields):
