Question

我想：

每个项目部分属于一个项目
每个解决方案属于一个 projectart（以及通过的项目）那个项目部分。
每张图片都属于一个解决方案（以及项目和项目部分通过该解决方案。）
每个文件属于一个解决方案（和项目和 projectpart通过该解决方案。）
每个网址都像简单一样简短可能的。
出现“projectpart”的每个案例作为每个URL中的“部分”。（我不能在Heroku上调用模型“part”。）

谁能告诉我为什么这样......

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

...在我的网址中留下了一大堆“projectpart”案例......

                                          /:controller/:action/:id.:format

...但是还没有像这样生成基本的URL帮助器？

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

顺便说一句，除了将每个URL中的“projectpart”更改为“part”之外的所有内容都使用这种更详细的语法正常工作：

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

关于路线生成问题的答案是:shallow => true

提供浅选项将为内部资源的收集方法创建更长的路由，同时为这些嵌套资源的成员方法提供浅层路由。仔细看看创建的路线，你会看到这一点。

基本上需要id（编辑，更新，显示，销毁）的路由将是仅包含最内层资源的短路径。不需要id（index，new）的路由会稍微长一些，包含直接的父路径。

您不需要project_projectpart_path，因为project_projectpart中的项目可以隐含在项目部分中。而只需将projectpart_path用于现有项目部分。

你的第二个例子提供了那些缺失的路由，因为它从不给出浅层选项。

在网址中将'projectpart'更改为'part'就像在其定义中添加：as选项一样简单。抱歉，它不适用于速记：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

浅层嵌套Rails路由：as
