title: rails redirect_to post
body: <p>I saw an example in the book <em>The Rails 3 Way</em> that says</p>
  
  <pre><code>redirect_to post
  </code></pre>
  
  <p>Does this have some special meaning because of the <code>post</code>, or if it is just a poor choice for an example and the <code>post</code> is just a domain object and it's redirecting to the url for that object.</p>
