First of all, you are not getting a JSON response from MongoDB — you are getting an Event document object. If you want to pass it to Twig, instead of returning a response, return an array (since you're using the @Template annotation:

return array('event' => $event);

The object will be accessible in your template as event.

I'm a little bit confused. if i return the event document as an array to the twig template i'm getting an error: `Method "eventTitle" for object "Doctrine\ODM\MongoDB\LoggableCursor" does not exist in DungeonEventBundle:Event:view.html.twig at line 4`. what's wrong here? :/ – varg Dec 04 '11 at 15:47
The problem is that `$event` is not a single document, but a collection of documents. Use `find()` (or `findOneById()`) instead of `findById()`. – Elnur Abdurrakhimov Dec 04 '11 at 16:26

The best practice describe here would be to use a base.json.twig template, as described here and here, instead of Response(json_encode($data)).
