最好的方法是:

destroy rake db:  rake db:rollback

支架:

rails destroy scaffold Name_of_script

用于在轨道中生成脚手架

rails generate scaffold MODEL_GOES_HERE

用于在轨道上撤消脚手架-

rails destroy scaffold MODEL_GOES_HERE

rails g scaffold MyFoo 

用于生成和

rails d scaffold MyFoo

为消除

Rishav Rastogi是对的，rails 3.0或更高版本:

rails generate scaffold ...

rails destroy scaffold ...

要生成脚手架:

rails generate scaffold abc

恢复脚手架:

rails destroy scaffold abc

如果您已经为它运行了迁移，只需回滚即可

rake db:rollback STEP=1

是的，刑台本身和它上面的所有东西。

destroy命令与generate相反，它将撤销一个命令。只需要像generate一样传递它的名字，它就会从你的项目中删除:

rails generate scaffold posts title:string content:text
rails destroy scaffold posts title:string content:text
