Rails 3 具有变量命名空间的路由资源

是否可以有一个变量命名空间？我有如下的宁静资源：

resources :articles
resources :persons

但我需要将它们限定在变量命名空间内，以便它响应以下形式的 URL：

':edition/:controller/:action/:id' 

例如：

/foobar/article/edit/123 or /bazbam/person/edit/345

对于每个资源。这可能吗？resources方法，还是我必须手工制作这些？我不知道可能的值:edition提前时间;这些会在a中查找before_filter in my ApplicationController.

这就是我需要做的全部吗？

scope ':edition' do
  resources :articles
  resources :matches
  resources :teams
end

更新：当使用上面的范围指令时，我得到了我想要的路由：

    articles GET    /:edition/articles(.:format)          {:action=>"index", :controller=>"articles"}
             POST   /:edition/articles(.:format)          {:action=>"create", :controller=>"articles"}
 new_article GET    /:edition/articles/new(.:format)      {:action=>"new", :controller=>"articles"}
edit_article GET    /:edition/articles/:id/edit(.:format) {:action=>"edit", :controller=>"articles"}
     article GET    /:edition/articles/:id(.:format)      {:action=>"show", :controller=>"articles"}
             PUT    /:edition/articles/:id(.:format)      {:action=>"update", :controller=>"articles"}
             DELETE /:edition/articles/:id(.:format)      {:action=>"destroy", :controller=>"articles"}
     matches GET    /:edition/matches(.:format)           {:action=>"index", :controller=>"matches"}
             POST   /:edition/matches(.:format)           {:action=>"create", :controller=>"matches"}
   new_match GET    /:edition/matches/new(.:format)       {:action=>"new", :controller=>"matches"}
  edit_match GET    /:edition/matches/:id/edit(.:format)  {:action=>"edit", :controller=>"matches"}
       match GET    /:edition/matches/:id(.:format)       {:action=>"show", :controller=>"matches"}
             PUT    /:edition/matches/:id(.:format)       {:action=>"update", :controller=>"matches"}
             DELETE /:edition/matches/:id(.:format)       {:action=>"destroy", :controller=>"matches"}
       teams GET    /:edition/teams(.:format)             {:action=>"index", :controller=>"teams"}
             POST   /:edition/teams(.:format)             {:action=>"create", :controller=>"teams"}
    new_team GET    /:edition/teams/new(.:format)         {:action=>"new", :controller=>"teams"}
   edit_team GET    /:edition/teams/:id/edit(.:format)    {:action=>"edit", :controller=>"teams"}
        team GET    /:edition/teams/:id(.:format)         {:action=>"show", :controller=>"teams"}
             PUT    /:edition/teams/:id(.:format)         {:action=>"update", :controller=>"teams"}
             DELETE /:edition/teams/:id(.:format)         {:action=>"destroy", :controller=>"teams"}

我现在可以参考:edition in my ApplicationController:

class ApplicationController < ActionController::Base
  protect_from_forgery

  before_filter :authenticate_user!
  before_filter :get_edition

  def get_edition
    @edition = Edition.first(:conditions => { :FriendlyName => params[:edition] } )
  end

end

现在我只想确保这是实现这一目标的最佳方法。

实际上，您可以执行以下操作：

my_var = "persons"
resources my_var.to_sym

The to_sym字符串上的方法将其更改为符号
