路線/相冊/新地圖到相冊＃顯示

Question

鐵軌邊的文件說：

GET |/albums/new |相冊＃new |返回一個HTML表單創建 新專輯

但是，當我嘗試這樣做，我得到：

Started GET "/api/albums/new" for 172.18.0.1 at 2017-08-10 20:12:06 +0000 
Processing by API::AlbumsController#show as */* 

這是我關於專輯的路由器：

Rails.application.routes.draw do 
    namespace :api, constraints: {format: :json} do 
    resources :albums 
    put  '/albums/:id/photo/:photo' => "albums#add_photo" 
    put  '/albums/:id/bucket'  => "albums#add_bucket" 
    get  '/albums/:id/photos'  => 'albums#photos' 
    end 
end 

問題： 爲什麼/ API /專輯/新地圖到API :: AlbumsController＃顯示而不是API :: AlbumsController＃新

增加：

我rake routes輸出：

鑑於你的路線，而事實上，你是一個--apionly應用程序（如你在評論中指出），沒有new行動，也不是一個edit行動。它們（通常）在API中不是有用的概念;正如文檔所述，它通常用於呈現一個HTML表單，它在API中沒有位置。

GET "/api/albums/new"路徑路由到API::AlbumsController#show，因爲它匹配GET "/api/albums/:id"，所以"new"被解釋爲一個標識符。
