路線錯誤 - Ruby on Rails的

我已經有這個在我的路線文件：路線錯誤 - Ruby on Rails的

namespace :api do 
    root :to => 'graphs#index' #default page when accessing /admin 
    resources :graphs, :defaults => { :format => 'json' } 

    match ':graphs/:id(/:method)' 
    end

但是當我嘗試打開：

mydomain.com/api

或

mydomain.com/api/graphs/

我得到了以下錯誤：

你運行'耙routes'查看路線圖？ –

誠然，我不是那熟悉的匹配語句，但它看起來像你缺少它的第二部分，如：

match ':graphs/:id(/:method)' => 'pages#something'

正如我在這裏看到：

Rails routes match full hostname with multiple period in between

這裏：

understanding rails routes: match vs root in routes.rb

這裏有一個similar問題在「到」中的操作未正確說明。

你建議我使用別的東西而不是匹配嗎？如果我想做這樣的事情：match'：graphs /：id（/：method）'=>'pages＃：methodFromUrl' – glarkou

我認爲這裏有一個例子 - http://edgeguides.rubyonrails.org/ routing.html - 例如match'：controller /：action /：id/with_user /：user_id' 此路線將響應諸如/ photos/show/1/with_user/2之類的路徑。在這種情況下，params會是{：controller =>「photos」，：action =>「show」，：id =>「1」，：user_id =>「2」}。 –

我在RESTful路由中也遇到同樣的問題。

這裏是例如：

resources :categories do 
     member do 
     post 'sort/:move', constraints: { move: /up|down/ } 
     end 
    end

請求「/類別/ 1 /排序/向上」導致相同的錯誤。

正如你所看到的那樣：移動參數會誤導控制器/動作使用的軌道。所以你需要指定「動作」選項明確：

post 'sort/:move', constraints: { move: /up|down/ }, action: 'sort'

注意，如果使用「到」選項不能省略控制器名稱：

post 'sort/:move', constraints: { move: /up|down/ }, to: 'categories#sort'
