title: Comma separated string to symbols
body: <p>Do you know any elegant way to achieve this in ruby plz ?</p>
  
  <pre><code> string = 'title,url'
   #expected final variable =&gt; :title,:url or 'title','url'
  </code></pre>
  
  <p>I've looked in the API documentation (both ruby and rails) and didn't find any simple method, before writing any loop I wanted to be sure I wasn't missing something.</p>
  
  <p>Thx !</p>
