title: Rails 3, create a new route for every resource
body: <p>In a project I'm working on I'd like to add the same route for multiple resources. I know I can do this</p>
  
  <pre><code>resources :one do
    collection do
      post 'common_action'
    end
  end
  resources :two do
    collection do
      post 'common_action'
    end
  end  
  </code></pre>
  
  <p>I have at least 10 different resources which all need the same route, as each controller will have the same action. Is there a way to define this less repetitively?</p>
