问题描述
我最近开始深入文档，发现它有两种不同类型的迁移：
I recently began digging into the South documentation and discovered that it had two distinct types of migrations:
- schemamigration
- datamigration
由于我的无知，我一直在为所有事物使用方案。换句话说，即使我有一些真正的数据迁移，我只是用南方的模式迁移来转换数据（没有明显的后果）。
As a result of my ignorance, I've always used schemamigrations for everything. In other words, even if I had something that was truly a "data migration", I'd simply used South's schemamigration to convert the data (with no apparent consequences).
当我阅读文档时，我没有看到这种方法的错误。有没有人知道两个迁移之间的根本区别，以及我坚持使用模式的错误呢？
As I read the documentation, I'm not seeing a fault in this approach. Does anyone know the fundamental difference between the two migrations and what I may be missing by sticking with schemamigrations?
推荐答案
的南方：
正如所示，唯一的区别是数据迁移不是
干运行，如果你有一个数据库需要它（MySQL）。否则，
几乎没有什么区别，至少在目前 - 管理
命令有所不同（这一切都是关于用户界面分离，基本上是
）。
As that shows, the only difference is that data migrations aren't dry-run if you have a database that requires it (MySQL). Otherwise, there's little difference, at least at the moment - the management commands differ, though (it's all about user interface separation, essentially).
