因为我有同样的抽象模型中的每一个应用程序的模型我必须避免冗余 我刚搬到我共同的抽象模型到新的应用程序,我创建并把它称为共同为什么我得到django.core.exceptions.AppRegistryNotReady:模型尚未加载?
常见Models.py现在
from django.db import models
LANGUAGE_CHOICES = (
('E','ENGLISH'),
('F','FRENCH'),
('S','SPANISH'),
)
class CommonInfo(models.Model):
created = models.DateTimeField("creation date", auto_now_add=True)
modified = models.DateTimeField("modification date", auto_now=True)
description = models.TextField()
class Meta:
abstract = True
然后我说我的共同应用的settings.py
最后,在我所有的应用程序,我添加
from common.models import CommonInfo
from common.models import LANGUAGE_CHOICES
运行的本地服务器之后,这是我在终端得到错误(完整的跟踪)

可能是什么问题呢?如果有更好的方法来分组所有常见的抽象模型和选择以避免随机数?
