title: ruby on rails descending loop increments
body: <p>How do I descent from 5 to 1 instead of going from 1 to 5? I have this...</p>
  
  <pre><code>&lt;div class="field-container rating"&gt;
    &lt;% (5..1).each do |i| %&gt;
    &lt;%= f.radio_button :rating, i, :id =&gt; "star#{i}" %&gt;
    &lt;% end %&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p><code>(1..5)</code> goes from 1, 2, 3, 4, 5. What is the correct way of going 5, 4, 3, 2, 1?</p>
