我应该扁平化Rails迁移吗? [英] Should I flatten Rails migrations?

问题描述

可以用db/schema.rb的内容替换db/migrate/*，这样您只需要执行一个迁移步骤即可.

It's possible to replace db/migrate/* with the contents of db/schema.rb, so that you only have one migration step.

你们有没有这样做?为什么?

Do any of you ever do this? Why?

推荐答案

为什么要这样做?如果您不想运行所有迁移，则可以只运行rake db:schema:load.迁移不(仅)用于初始化新数据库，而是用于将其迁移到另一个版本.

Why would you want to do this? You could just run rake db:schema:load if you don't want to run all migrations. Migrations are used not (only) to initialize a new database, but to migrate it to another version.
