Routing

說明

  • 簡單的說，就是設定你的「網頁路徑」，連接到對應的Action Controller

使用情境

  • 如何在網址後面再加上字串

使用方式

    Forum::Application.routes.draw do
      # The priority is based upon order of creation:
      # first created -> highest priority.

      # Sample of regular route: Rails 3.0 以前預設的開發方式
      match 'products/:id' => 'catalog#view' 
      # Keep in mind you can assign values other than :controller and :action

      # Sample of named route: 命名路由適用於不符合CRUD的情況
      match 'products/:id/purchase' => 'catalog#purchase', :as => :purchase
      # This route can be invoked with purchase_url(:id => product.id)

      # Sample resource route (maps HTTP verbs to controller actions automatically): RESTful路由的設定方式
      resources :products

      # Sample resource route with options:
      resources :products do
        # member 需要傳進ID /products/1/short
        member do
          get 'short'
          post 'toggle'
        end
        # collection 不用傳ID  /products/sold/
        collection do
         get 'sold'
        end
      end

      # Sample resource route with sub-resources: Nests Resources
      resources :products do
        resources :comments, :sales
        resource :seller
      end

      # Sample resource route with more complex sub-resources
      resources :products do
        resources :comments
        resources :sales do
          get 'recent', :on => :collection
        end
      end

      # Sample resource route within a namespace: 這個路由方式可以在相同名稱下的resources設定不同的存取權限，如後台
      namespace :admin do
      #     # Directs /admin/products/* to Admin::ProductsController
      #     # (app/controllers/admin/products_controller.rb)
        resources :products
      end

      # See how all your routes lay out with "rake routes"

      # This is a legacy wild controller route that's not recommended for RESTful applications.
      # Note: This route will make all actions in every controller accessible via GET requests.
      # match ':controller(/:action(/:id(.:format)))'
    end
