浅嵌套轨道布线:AS

routing ruby-on-rails

steven_noble · 技术社区 · 15 年前

我想要:

属于的每个项目部件项目。
每个解决方案都属于 ProjectArt(通过那个项目部分)。
每个图像都属于一个解决方案 (以及一个项目和一个项目部分) 通过那个解决方案。)
每个文档都属于解决方案(以及项目和通过该解决方案进行项目部分。)
每个URL都要像可能的。
出现“ProjectPart”的每一个案例作为每个URL的“部分”。(我不能) 把Heroku上的模型称为“零件”。

有人能告诉我为什么…

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URL中留下了一大堆“projectpart”…

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

…但是没有生成基本的URL帮助程序,像这样吗?

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,其他所有内容都可以使用更详细的语法:

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

关于路线生成问题的答案是 :shallow => true

提供Shallow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较浅的路由。仔细看看创建的路线,你会发现这一点。

基本上,需要ID(编辑、更新、显示、销毁)的路由将是只包含最内部资源的短路由。不需要ID(index,new)的路由将稍长一些,包含直接父路由。

你不需要 project_projectpart_path 因为项目在 project_projectpart 可以从项目部分暗示。只需使用 projectpart_path 对于现有项目部件。

第二个例子提供了那些丢失的路径,因为它从不提供浅层选项。

在URL中将“projectpart”更改为“part”与在其定义中添加:as选项一样简单。对不起,它不能用速记:有很多版本

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
