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.
