你也需要在摧毁脚手架后回滚迁移

rails destroy scaffold 'scaffoldname'
rake db:rollback

你也需要在摧毁脚手架后回滚迁移

rails destroy scaffold 'scaffoldname'
rake db:rollback

Rails [option] scaffold脚手架名称

选项

g    generate
d    destroy

如果有的话

rails g  scaffold myFoo

然后反向使用

rails d scaffold MyFoo

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

最好的方法是:

destroy rake db:  rake db:rollback

支架:

rails destroy scaffold Name_of_script

Rishav Rastogi是对的，rails 3.0或更高版本:

rails generate scaffold ...

rails destroy scaffold ...
