Rails 3 - 嵌套资源和成员/集合

Question

有没有办法避免这样做...

resources :parents do
  resources :children do
    collection do
      get "/search/:term/:offset/:limit.:format", :action => "search", :constraints => { :term => /\w+/, :offset => /\d+/, :limit => /\d+/ }
    end
  end
end

resources :children do
  collection do
    get "/search/:term/:offset/:limit.:format", :action => "search", :constraints => { :term => /\w+/, :offset => /\d+/, :limit => /\d+/ }
  end
end

我认为这样做是可能的......

resources :parents do
  resources :children do
end

resources :children do
  collection do
    get "/search/:term/:offset/:limit.:format", :action => "search", :constraints => { :term => /\w+/, :offset => /\d+/, :limit => /\d+/ }
  end
end

原因是我希望能够同时使用这两条路线...

/children/search/term/0/10
/parents/1/children/search/term/0/10

Answer 1

这似乎可以解决问题

def define_children 
  resources :children do
    collection do
      get :search
    end
  end
end

define_children
resources :parents do
  define_children
end

如果使用了通过parent 的路由，则:parent_id 将设置在params 中。否则不会出现。为了清楚起见，我省略了约束。此外，您可能应该将.format 设为可选。
