title: Rails - controller to separate view
body: <p>In rails, I can say</p>
  
  <pre><code>match 'user/:id/article/:id' =&gt; 'article#show'
  </code></pre>
  
  <p>Here the article#show, would use the Article controller, in the show action. And it would present the show view in the article folder. But what if I wanted to be specific and say show action in article controller, and present the xxx view in the xxx folder.</p>
