ruby​​ on rails 4，設置routes.rb和資源do

Question

我不知道如何設置多於1個「item」的資源do方法。我有3個腳手架，即Post，Comment，Response。我想達到在耙路線： 'new_post_comment_response => /職位/身份證/評論/ ID /響應/新'

的關係是：

有很多

「後型號：評論 有很多：響應

有許多

評價模型：響應 belongs_to的：後

響應模型 belongs_to的：發佈 belongs_to的：發表評論」

在routes.rb中我已設置：

資源：帖子做 資源：評論，除了：[：秀：指數] 結束

資源：備註，請 資源：響應，除了： [：show，：index] end

但是我想在耙路中有三個項目，因爲我要做一些「論壇中的三個響應（評論後的迴應 - 評論）」 。你懂我的意思嗎？

所以，我的問題是：如何設置資源和控制器來檢測Post和Comment ID，以及如何設置資源。

感謝您的幫助！

Answer 1

您基本上只需要按照您希望的方式嵌套資源。這意味着帖子應該嵌套評論和回覆，評論應該嵌套迴應。假設我正確地閱讀了你的要求，你可以沿着這條線設置一些東西。

concern :responsable do 
    resources :responses, except: [:show, :index] 
end 

resources :posts, concerns: :responsable do 
    resources :comments, except: [:show, :index], concerns: :responsable 
end 

這個問題只是一種重用一套通用路線的方法。更多關於它在documentation。

如果你運行rake路線，你應該結束了以下路徑：

post_comment_responses POST /posts/:post_id/comments/:comment_id/responses(.:format)   responses#create 
new_post_comment_response GET /posts/:post_id/comments/:comment_id/responses/new(.:format)  responses#new
