How to get associations in Doctrine entity? - doctrine-orm

Question

I hope it's possible in Doctrine2. I know Propel does that automatically. What I want to do is this:
I have two tables:
workflow (id, name)
inbox (id, workflow_id, name)
And two entities:
Workflow and Inbox
In my Inbox entity I, of course, have this (to relate two tables):
/**
* #ORM\ManyToOne(targetEntity="Workflow")
* #ORM\JoinColumn(nullable=false)
*/
protected $workflow;
Everything works great. However, I want to be able to get inboxes from the Workflow entity that are associated with that workflow. I can't find how to do it.
Propel does that very simple, you would just do something like this:
$workflow = WorkflowQuery::create()
->filterById(1)
->findOne(1);
$inboxes = $workflow->getInboxs()
//Propel just addes 's' to methods that return associations
How, similar this can be done in Doctrine2? Something like this:
$workflow = $this->getRepository('MyBundle:Workflow')->findById(1);
$inboxes = $workflow->getInboxes();
So, is there a way to do this? Thank you.

Change in controller:
$workflow = $this->getDoctrine()->getRepository('MyBundle:Workflow')->find(1);
$inboxes = $workflow->getInboxes();
Don't forget that you need
// Workflow entity
public function __construct()
{
// make `use` statement for this, not long
$this->inboxes = new \Doctrine\Common\Collections\ArrayCollection() ;
}
and
/**
* #ORM\OneToMany(targetEntity="Inbox", mappedBy="workflow", cascade={"persist"})
*/
protected $inboxes ;
public function getInboxes() { return $this->inboxes ; }
// setInboxes(), addInbox(), removeInbox() here
