在 Rails 中撤消脚手架 [英] Undo scaffolding in Rails

问题描述

有什么办法可以撤销"Rails 中脚手架命令的效果?

Is there any way to 'undo' the effects of a scaffold command in Rails?

推荐答案

首先，如果您已经运行了 scaffold 命令生成的迁移，则必须执行先回滚.

First, if you have already run the migrations generated by the scaffold command, you have to perform a rollback first.

rake db:rollback

您可以使用以下方法创建脚手架:

You can create scaffolding using:

rails generate scaffold MyFoo 

(或类似的)，并且您可以使用

(or similar), and you can destroy/undo it using

rails destroy scaffold MyFoo

这将删除 generate 创建的所有文件，但不会删除您可能手动进行的任何其他更改.

That will delete all the files created by generate, but not any additional changes you may have made manually.
