当我做的
- rails g model user name:string
- rails g controller users index create new destroy show
并编辑config / routes.rb来添加：
- resource :users
捆绑执行rake路线给出：
- users POST /users(.:format) {:action=>"create",:controller=>"users"}
- new_users GET /users/new(.:format) {:action=>"new",:controller=>"users"}
- edit_users GET /users/edit(.:format) {:action=>"edit",:controller=>"users"}
- GET /users(.:format) {:action=>"show",:controller=>"users"}
- PUT /users(.:format) {:action=>"update",:controller=>"users"}
- DELETE /users(.:format) {:action=>"destroy",:controller=>"users"}
但是,当我做
- rails g resource users name:string
(它自动添加资源：用户到config / routes.rb)
捆绑执行耙子路由
我得到
- users GET /users(.:format) {:action=>"index",:controller=>"users"}
- POST /users(.:format) {:action=>"create",:controller=>"users"}
- new_user GET /users/new(.:format) {:action=>"new",:controller=>"users"}
- edit_user GET /users/:id/edit(.:format) {:action=>"edit",:controller=>"users"}
- user GET /users/:id(.:format) {:action=>"show",:controller=>"users"}
- PUT /users/:id(.:format) {:action=>"update",:controller=>"users"}
- DELETE /users/:id(.:format) {:action=>"destroy",:controller=>"users"}
所以我的问题是
当我生成一个控制器,我该如何获得正确的帮助方法
link_to’Destroy’,instance,：method => ：删除
工作？
因为目前它给出错误user_path没有定义.
解决方法
你应该打电话
- rails g controller user index create new destroy show
代替
- rails g controller users index create new destroy show
为了获得资源：用户给你想要的帮手.
后者导致Rails假定用户是一个单一的对象,资源：用户应该创建一个所谓的单一资源：
http://guides.rubyonrails.org/routing.html#singular-resources
因此,user_path未定义,而users_path已定义.
