当我执行芹菜任务时，它给我：
值错误：相关模型 u'user。无法解析用户
堆栈跟踪是

这里 ConnectedUserPage 是一个带有架构的模型：
class ConnectedUserPage(TimeStampedModel):
user = models.ForeignKey('user.User', on_delete=models.PROTECT)
page = models.ForeignKey(FacebookPage, on_delete=models.PROTECT)
page_details = jsonb.JSONField()
我的版本是：
celery==4.1.1
django-celery-beat==1.1.1
django-celery-results==1.0.1
Django==1.11.13
如果我直接从用户应用程序导入用户模型，我就会陷入循环导入。
任何帮助将不胜感激，现在在这个循环中停留了一段时间。
User在哪里定义？这是 Django 自己的用户模型吗？如果是这种情况，您可以直接使用用户模型：
from django.contrib.auth import get_user_model
User = get_user_model()
class ConnectedUserPage(TimeStampedModel):
user = models.ForeignKey(User, unique=True)
或者你也可以做
from django.conf import settings
class ConnectedUserPage(TimeStampedModel):
user = models.ForeignKey(settings.AUTH_USER_MODEL)
如果是你自己提供的用户模型，你确定userINSTALLED_APPS吗？
