資源如何在Rails中工作？

Question

這是我目前工作的routes.rb文件：

Rails.application.routes.draw do 

    get 'static_pages/help' 
    get 'static_pages/test', as: "can_do_this" 
    get 'static_pages/home', to: "static_pages#home", as: "home" 
    root 'application#hello' 

end 

但是，如果我添加一行：

Rails.application.routes.draw do 

    resources :static_pages #added this line 
    get 'static_pages/help' 
    get 'static_pages/test', as: "can_do_this" 
    get 'static_pages/home', to: "static_pages#home", as: "home" 
    root 'application#hello' 

end 

然後我的代碼休息和我的網頁上我有任何的內容不會顯示。有人能向我解釋這條線是什麼以及如何使用它？

Answer 1

資源：static_pages將創建這些7條路線你

GET  /static_pages     static_pages#index 
GET  /static_pages/new    static_pages#new 
POST  /static_pages     static_pages#create 
GET  /static_pages/:id    static_pages#show 
GET  /static_pages/:id/edit   static_pages#edit 
PATCH/PUT /static_pages/:id    static_pages#update 
DELETE  /static_pages/:id    static_pages#destroy 

當你需要有控制器代表static_pages以及和所需的看法。

希望這有助於..

讓我知道，如果你還有任何疑問..

添加這行代碼在你routes.rb

resources :static_pages 

將產生以下寧靜的路線

static_pages GET /static_pages(.:format)   static_pages#index 
       POST /static_pages(.:format)   static_pages#create 
new_static_page GET /static_pages/new(.:format)  static_pages#new 
edit_static_page GET /static_pages/:id/edit(.:format) static_pages#edit 
    static_page GET /static_pages/:id(.:format)  static_pages#show 
       PATCH /static_pages/:id(.:format)  static_pages#update 
       PUT /static_pages/:id(.:format)  static_pages#update 
       DELETE /static_pages/:id(.:format)  static_pages#destroy 

Answer 3

正如其他答案中提到的，resources :static_pages創建了幾條路線。其中有這樣一句：

static_page GET /static_pages/:id(.:format)  static_pages#show 

所以，當你提出要求，例如，http://localhost:3000/static_pages/help，它是這條路線，這個URL匹配。它使用參數{'id' => "help"}調用StaticPagesController#show動作。您的自定義help操作未被考慮，因爲已找到匹配路線。

一對夫婦在這裏可能的方式：

1. 從show動作（通過ID）服務您的靜態頁面和刪除自定義路線。
2. 將您的自定義路線後的地方resources :static_pages，以便自定義的路線首先匹配。
