Final part which consist of just some "incomplete" thoughts on how to deal with Circular reference exception when using the Symfony Serializer Component, this goes through how you would use the MaxDepth annotation to avoid the Circular Reference Exception, also the CircularReferenceHandler which you can use to return whatever you want instead of returning the same object and be stuck in an infinite loop, the last thing is the ignore attributes option which as you saw i didn't show anything useful in that area, you HAVE to figure that one out by yourself.
