title: Sentry/Sentinel if user is in role
body: <p>I am trying to run a check to see if the current user is in a certain role with Cartalyst's Sentinel/Sentry package.</p>
  
  <p>I have found <code>Sentinel::inRole('admin')</code> but can't seem to get it to work. I want something like this:</p>
  
  <p><code>if(Sentinel::getUser()->hasRole('admin'){ // do some stuff }</code></p>
  
  <p>I've searched and searched for this and can't find an example to work with. Should I be looking more into permissions or something?</p>
  
  <p>Hopefully someone out there can point me in the right direction.</p>
  
  <p>Cheers</p>
