ROR 中的 DRY 航线说明

我在 json Rest 应用程序中嵌套了路由组合，用于不同的下拉列表和分组

 resources :cities, :only =>[:index,:show] 
 resources :regions, :only =>[:index,:show] do
     resources :cities, :only=>[:index, :show] 
 end    
 resources :countries, :only=>[:index,:show] do
   resources :cities, :only=>[:index,:show] 
   resources :regions, :only=>[:index,:show] 
 end

有没有一种方法可以更干燥地描述它？

原文

I have nested combination of routes in json rest application used for different dropdown lists and grouping

 resources :cities, :only =>[:index,:show] 
 resources :regions, :only =>[:index,:show] do
     resources :cities, :only=>[:index, :show] 
 end    
 resources :countries, :only=>[:index,:show] do
   resources :cities, :only=>[:index,:show] 
   resources :regions, :only=>[:index,:show] 
 end

Is there a way to describe it more DRY-way?

如果您确实需要这些路线，我认为您无能为力。也许您可以使用 with_options 以更简洁的方式编写它：

  with_options :only => [:index, :show] do |w|

    w.resources :cities
    w.resources :regions do
      w.resources :cities
    end

    w.resources :countries do
      w.resources :cities
      w.resources :regions
    end

  end

If you actually need these routes I think you can't do very much about it. Probably you can just write it in a more concise way using with_options:

  with_options :only => [:index, :show] do |w|

    w.resources :cities
    w.resources :regions do
      w.resources :cities
    end

    w.resources :countries do
      w.resources :cities
      w.resources :regions
    end

  end
