修复：我从django.contrib.auth.models.User导入User模型，忘记将其替换为.models.User

我是Django的初学者，学习如何在我的账户应用程序中使用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：no such table：auth_user

Request URL: http://localhost:8000/accounts/register/

Django Version: 4.2.6

Python Version: 3.11.6

Installed Applications:

['django.contrib.admin',

 'django.contrib.auth',

 'django.contrib.contenttypes',

 'django.contrib.sessions',

 'django.contrib.messages',

 'django.contrib.staticfiles',

 'accounts.apps.AccountsConfig']

Installed Middleware:

['django.middleware.security.SecurityMiddleware',

 'django.contrib.sessions.middleware.SessionMiddleware',

 'django.middleware.common.CommonMiddleware',

 'django.middleware.csrf.CsrfViewMiddleware',

 'django.contrib.auth.middleware.AuthenticationMiddleware',

 'django.contrib.messages.middleware.MessageMiddleware',

 'django.middleware.clickjacking.XFrameOptionsMiddleware']

Traceback (most recent call last):

我所尝试的：

  1. python manage.py makemigrations && python manage.py migrate
    1.从我的帐户应用程序中删除迁移文件。并再次按照第1步
    当我尝试使用django superuser、django Admin和django shell创建用户时，它完美地工作，没有任何错误。只有当我在注册表视图中调用保存（）时才会发生错误。

修复：我从django.contrib.auth.models.User导入User模型，忘记将其替换为.models.User

您是否在settings.py?“AUTH_USER_MODEL = 'accounts.User'“中指定了新用户
