Question

rails edge文档说：

GET | / albums / new |专辑#new |返回一个用于创建的HTML表单新专辑

但是当我尝试这样做时，我得到了：

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

这是关于专辑的路由器：

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

问题：那么为什么/ api / albums / new映射到API :: AlbumsController＃show而不是API :: AlbumsController #new

增加：

我的rake routes输出：

根据您的路线，以及（正如您在评论中指出的那样）您的--apionly应用是一个事实，没有new动作，也没有edit动作。它们（通常）在API中不是有用的概念;正如文档所述，它通常用于呈现HTML表单，而这在HTML中没有任何地方。

GET "/api/albums/new"路径路由到API::AlbumsController#show，因为它与GET "/api/albums/:id"匹配，因此"new"被解释为标识符。

路线/专辑/新地图到专辑#show
