Django南迁移AttributeError [英] Django South migration AttributeError

问题描述

当我在Django(1.4)中迁移South(0.7.5)时遇到此错误.我最近将Timezone设置更改为false，即USE_TZ = False来解决另一个问题.有任何想法吗?谢谢

I'm suffering from this error when migrating South (0.7.5) in Django (1.4). I recently changed the Timezone setting to false, i.e. USE_TZ = False to fix another problem. Any ideas? Thanks

推荐答案

可能为时已晚，但我认为与TZ没有任何关系.

It may be too late, but I don't think it has anything to do with TZ.

每个迁移文件都具有如下声明:

Every migration file has a declaration like:

class Migration(SchemaMigration):
    ...

AttributeError来自找不到声明的迁移类.

The AttributeError comes from not finding this Migration class declared.

检查您所有的迁移是否都具有这样的迁移.否则，请提供更多详细信息.

Check whether all of your migrations have one like that. Otherwise please provide more details.
