title: Rails - Radio Buttons for collection sets
body: <p>I have the following which outputs a select box:</p>
  
  <pre><code>&lt;%= f.label :request_type_id %&gt;&lt;br /&gt;
  &lt;% requestTypes = RequestType.all %&gt;
  &lt;%= f.collection_select :request_type_id, requestTypes, :id, :title, :prompt =&gt; true %&gt;
  </code></pre>
  
  <p>What is the rails method to instead output Radio Buttons?</p>
