淺嵌套導軌和路由：爲

Question

我想：

• 每projectpart屬於一個 項目。

• 每個屬於 項目的解決方案（以及通過 即projectpart）的項目。

• 每一個形象，屬於一個解決方案 （以及在項目和projectpart 通過該解決方案。）

• 每份文件，屬於 解決方案（以及在項目和 projectpart通過該解決方案。）

• 每個網址都以儘可能短，簡單 可能。

• 每個「projectpart」在每個URL中出現 爲「部分」。 （我不能 呼叫在Heroku模型「的一部分」。）

誰能告訴我爲什麼......

ActionController::Routing::Routes.draw do |map| 
    map.resources :projects, :shallow => true do |project| 
    project.resources :projectparts do |part| 
     part.resources :solutions do |solution| 
     solution.resources :images 
     solution.resources :documents 
     end 
    end 
    end 
    map.connect ':controller/:action/:id' 
    map.connect ':controller/:action/:id.:format' 
end 

...離開了一大堆的案件「項目部分」在我的網址...

...但尚未生成基本的URL助手，像這樣？

undefined method `project_projectpart_path' for #<ActionView::Base:0x3438ffc> (ActionView::TemplateError) 

順便說一句，只是改變「projectpart」在每一個URL「部分」一切工作正常，這個更詳細的語法：

ActionController::Routing::Routes.draw do |map| 


    map.resources :projects, :has_many => :projectparts 
    map.resources :projects, :has_many => :solutions 
    map.resources :projects, :has_many => :images 
    map.resources :projects, :has_many => :documents 
    map.resources :projectparts, :has_many => :solutions 
    map.resources :projectparts, :has_many => :images 
    map.resources :projectparts, :has_many => :documents 
    map.resources :solutions, :has_many => :images 
    map.resources :solutions, :has_many => :documents 
    map.resources :images 
    map.resources :documents 


    map.connect ':controller/:action/:id' 
    map.connect ':controller/:action/:id.:format' 

end 

Answer 1

有關線路生成的回答你的問題是:shallow => true

提供淺層選項將爲內部資源的收集方法創建更長的路由，同時爲這些嵌套資源的成員方法提供淺層路由。仔細看看創建的路線，你會看到這個。

本質路線需要一個ID（編輯，更新，顯示，銷燬）將僅含內大部分資源的短單。不需要id（index，new）的路由會略長一些，包含直接父節點。

你不需要project_projectpart_path因爲project_projectpart項目可以從項目部分暗示。現在的項目部件只需使用projectpart_path。

你的第二個例子提供了那些缺少的路由，因爲它從不給淺選項。

在urls中將'projectpart'更改爲'part'與添加：as選項一樣簡單。對不起，它不適用於速記：has_many版本

map.resources :projects, :shallow => true do |project| 
    project.resources :projectparts, :as => "part" do |part| 
    part.resources :solutions do |solution| 
     solution.resources :images 
     solution.resources :documents 
    end 
    end 
end
