python - Django 查找错误 : App 'accounts' doesn't have a 'User' model

Question

从 Django 1.10 升级到 1.11 后，我几乎在做任何事情时都遇到了问题。我无法启动我的服务器，也无法运行 manage.py。

在升级之前，我没有收到这个问题，所以我不确定从那时起发生了什么变化会导致这个问题。

我也已经尝试删除数据库，没有任何改变。

我的 settings.py AUTH_USER_MODEL/INSTALLED_APPS:

AUTH_USER_MODEL = 'accounts.User'

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'accounts.apps.AccountsConfig',
    'forum.apps.ForumConfig',
]

我的用户模型:

class User(AbstractUser):
    profile_picture = models.ImageField(null=True, blank=True)
    birth_date = models.DateField(null=True, blank=True)

错误:

Answer 1

我已经设法解决了这个问题。问题是我的 CustomUserAdmin(管理页面中自定义字段的扩展 UserAdmin)在升级到 1.11 后不能再出现在我的 models.py 中。它现在在我的 admin.py 中，问题不再出现。
