Question

我正在尝试在我的应用中设置django-notifications。我按照说明安装它，这非常简单：https://github.com/brantyoung/django-notifications#installation

当我运行manage.py migrate notifications时，我得到：

django.db.utils.ProgrammingError: (1146, "Table '{{database}}.notifications_notification' doesn't exist")

我很茫然。

在迁移数据之前忘记运行syncdb。该表不存在，因为它是创建它的syncdb，而不是迁移。

参考：http://south.readthedocs.org/en/latest/tutorial/part1.html

（如果抱怨不存在south_migrationhistory失败，则在安装South后忘记运行syncdb。）

Django通知不会同步
