Ruby On Rails -- routes.rb

本文深入解析Rails中routes配置的各类路由实例,包括根路由、常规路由、资源路由、嵌套路由、命名空间路由等,并通过实际操作展示其意义与应用。

刚学rails,不知道路由的rails代码改怎么写,而config/routes.rb路由文件下有很多路由的例子,而又不知道有何意义。对各个例子分别执行bin/rake routes后可以看到如下,大概能知道其中的意义了;
大概分为:根路由、常规路由、资源路由(常规路由的合体)、嵌套的常规/资源路由、命名空间的路由;

=====================================================================
# You can have the root of your site routed with "root"
# 根路由
# root 'welcome#index'
---------------------------------------------------------------------
  root GET  /           welcome#index
=====================================================================
# Example of regular route:
# 常规的路由
#   get 'products/:id' => 'catalog#view'
---------------------------------------------------------------------
       GET  /products/:id(.:format) catalog#view
=====================================================================
# Example of named route that can be invoked with purchase_url(id: product.id)
# 购物类的(具体还short toggle sold怎么用还不清楚)
#   get 'products/:id/purchase' => 'catalog#purchase', as: :purchase
---------------------------------------------------------------------
 short_product GET    /products/:id/short(.:format)  products#short
toggle_product POST   /products/:id/toggle(.:format) products#toggle
 sold_products GET    /products/sold(.:format)       products#sold
      products GET    /products(.:format)            products#index
               POST   /products(.:format)            products#create
   new_product GET    /products/new(.:format)        products#new
  edit_product GET    /products/:id/edit(.:format)   products#edit
       product GET    /products/:id(.:format)        products#show
               PATCH  /products/:id(.:format)        products#update
               PUT    /products/:id(.:format)        products#update
               DELETE /products/:id(.:format)        products#destroy
=====================================================================
# Example resource route (maps HTTP verbs to controller actions automatically):
# 资源路由
# 使用资源路径可以快速声明资源式控制器所有的常规路由
# 无需分别为 index、show、new、edit、create、update 和 destroy 动作分别声明路由
#   resources :products
---------------------------------------------------------------------
    products GET    /products(.:format)          products#index
             POST   /products(.:format)          products#create
 new_product GET    /products/new(.:format)      products#new
edit_product GET    /products/:id/edit(.:format) products#edit
     product GET    /products/:id(.:format)      products#show
             PATCH  /products/:id(.:format)      products#update
             PUT    /products/:id(.:format)      products#update
             DELETE /products/:id(.:format)      products#destroy
=====================================================================
# Example resource route with options:
#   resources :products do
#     member do
#       get 'short'
#       post 'toggle'
#     end
#
#     collection do
#       get 'sold'
#     end
#   end
# 将常规路由嵌入资源路由
---------------------------------------------------------------------
 short_product GET    /products/:id/short(.:format)  products#short
toggle_product POST   /products/:id/toggle(.:format) products#toggle
 sold_products GET    /products/sold(.:format)       products#sold
      products GET    /products(.:format)            products#index
               POST   /products(.:format)            products#create
   new_product GET    /products/new(.:format)        products#new
  edit_product GET    /products/:id/edit(.:format)   products#edit
       product GET    /products/:id(.:format)        products#show
               PATCH  /products/:id(.:format)        products#update
               PUT    /products/:id(.:format)        products#update
               DELETE /products/:id(.:format)        products#destroy
=====================================================================
# Example resource route with sub-resources:
#   resources :products do
#     resources :comments, :sales
#     resource :seller
#   end
# 将资源路由嵌入资源路由(一般用于两个或多个关联的数据表)
