ruby-on-rails - 嵌套资源的 Rails 路线索引

Question

我正在寻找 rake paths 与嵌套资源的 index 路径不匹配的原因。

这是我的代码:

namespace :api do
  resources :photos do
    resource :comments
  end
end

这是命令的结果:rake paths | grep 注释

           batch_action_admin_user_comments POST       /admin/user_comments/batch_action(.:format)            admin/user_comments#batch_action
                        admin_user_comments GET        /admin/user_comments(.:format)                         admin/user_comments#index
                                            POST       /admin/user_comments(.:format)                         admin/user_comments#create
                     new_admin_user_comment GET        /admin/user_comments/new(.:format)                     admin/user_comments#new
                    edit_admin_user_comment GET        /admin/user_comments/:id/edit(.:format)                admin/user_comments#edit
                         admin_user_comment GET        /admin/user_comments/:id(.:format)                     admin/user_comments#show
                                            PATCH      /admin/user_comments/:id(.:format)                     admin/user_comments#update
                                            PUT        /admin/user_comments/:id(.:format)                     admin/user_comments#update
                                            DELETE     /admin/user_comments/:id(.:format)                     admin/user_comments#destroy
                             admin_comments GET        /admin/comments(.:format)                              admin/comments#index
                                            POST       /admin/comments(.:format)                              admin/comments#create
                              admin_comment GET        /admin/comments/:id(.:format)                          admin/comments#show
                         api_photo_comments POST       /api/photos/:photo_id/comments(.:format)               api/comments#create
                     new_api_photo_comments GET        /api/photos/:photo_id/comments/new(.:format)           api/comments#new
                    edit_api_photo_comments GET        /api/photos/:photo_id/comments/edit(.:format)          api/comments#edit
                                            GET        /api/photos/:photo_id/comments(.:format)               api/comments#show
                                            PATCH      /api/photos/:photo_id/comments(.:format)               api/comments#update
                                            PUT        /api/photos/:photo_id/comments(.:format)               api/comments#update
                                            DELETE     /api/photos/:photo_id/comments(.:format)               api/comments#destroy

我尝试将 only: [:create, :index] 添加到我的 comments 资源，但只有 create 路由可见。

根据有关nested-resources的文档我不明白发生了什么事。

感谢您的帮助。

Answer 1

这是因为您使用的是singular resource (资源:评论)

来自文档:

Sometimes, you have a resource that clients always look up without referencing an ID. For example, you would like /profile to always show the profile of the currently logged in user. In this case, you can use a singular resource to map /profile (rather than /profile/:id) to the show action

您需要使用标准的 resources 方法才能使其正常工作(resource 省略 index 操作):

#config/routes.rb
namespace :api do
  resources :photos do
    resources :comments
  end
end
