我有两个用户，mh00h1 和 mh00h2。我也有在我的 models.py 中定义以下内容的 modelA：
class Meta:
permissions = (
('read','read'),
('write','write'),
)
从一个外壳，我去设置权限：
>>>> frhde = create modelA instance
>>>> assign_perm('read', mh00h2, frhde)
DoesNotExist: Permission matching query does not exist. Lookup parameters were {'codename': u'read', 'content_type': <ContentType: modelA>}
我意识到在我添加并确认这一点South后并没有迁移我的模型。更改为显示未检测到更改。class MetamodelAreadread2South
$ /manage.py schemamigration myapp --auto

如何获得示意图迁移以正确更新数据库，或者是否有更好的方法来做到这一点，而不需要重做整个数据库？
谢谢你。
