title: Symfony2 call controller from another controller
body: <p>I'm new to symfony2 and I've been trying to find the best way to call a controller from within another.</p>
  
  <p>I have a list of events and I need an action to get all events and another action to get an event by ID but I don't want to keep repeating the doctrine calls each time I need to do this.</p>
  
  <p>I thought about making a controller with all event actions and then calling the needed action from within other controllers each time I need it, if there is a better way to do it, I'm open for any suggestions.</p>
  
  <p>thanks in advance.</p>
