title: Rails form_for select tag with option selected
body: <p>I am using a form_for to update a user profile.</p>
  
  <p>As part of the form I am using a select menu. The menu is filled from an array ie,</p>
  
  <pre><code>STATUS = [['Active', 'active'], ['In Active', 'inactive']]
  </code></pre>
  
  <p>Then in the form</p>
  
  <pre><code>&lt;%= f.select(:status, options_for_select(STATUS)) %&gt;
  </code></pre>
  
  <p>While this work's its not selecting the option which was previously selected on edit.</p>
  
  <p>Am I missing something ?</p>
