在创建rails项目时通常会用到
rails g modle xxx
rails g controller xxx
来创建model / controller 模块
当你要创建一个sells 的 controller时
不小心输入为 rails g controller sells, 根目录下会产生一大堆文件，但你又不想一个个目录的查找删除:
deleted: app/assets/javascripts/sells.coffee
deleted: app/assets/stylesheets/sells.scss
deleted: app/controllers/sells_controller.rb
deleted: app/helpers/sells_helper.rb
deleted: app/views/sells/profit_info.html.erb
deleted: app/views/sells/search_info.html.erb
deleted: app/views/sells/sell_data.html.erb
deleted: test/controllers/sells_controller_test.rb
所以直接执行rails d controller sells后
重新执行正确命令rails g controller sell即可。
如果你创建了错误modle
如果你需要创建 rails g model order country:string city_id:inter
结果不小心输入为 rails g model order country:string city_id:inte
只需要将g 替换为 d rails d model order country:string city_id:inte
重新输入正常的命令即可
创建错误 model后还执行了 rake db:migrate
首先删除重建model信息
回滚清除 db 信息,后重新创建db信息
rake db:drop
rake db:create
rake db:migrate
