title: Twig CamelCase Filter in Symfony2
body: <p>So I'm pretty new to Symfony2 and I'm trying to use the <code>camelize</code> filter in a twig template. However when I request the page I get an error saying that the filter doesn't exist:</p>
  
  <blockquote>
    <p>The filter "camelize" does not exist in ::base.html.twig</p>
  </blockquote>
  
  <p>Here's the line from my template file:</p>
  
  <blockquote>
    <p>{{ 'hello world' | camelize }}</p>
  </blockquote>
  
  <p>The filter is listed on Twig's <a href="https://github.com/vito/chyrp/wiki/Twig-Reference" rel="nofollow">quick reference page</a>. </p>
  
  <p>I'm confused, doesn't Symfony2 support all of twig's filters? There seem to be quite a few missing, why? And if it doesn't support them, then is there any way to add the missing ones in?</p>
  
  <p>Thanks in advance!</p>
  
  <p><strong>edit</strong> Ok, so it turns out I'm retarded and I need to remember to check that I've actually got the right git project. No wonder I was confused. Thanks replies!</p>
