Doctrine postLoad event for associations

Question

I currently have an entity which I would like to modify slightly upon load. This modification will be a one time change which will then be persisted in a new field along wit

Answer 1

I was able to load the associated Location objects within the postLoad event by using the initializeObject() method on the Entity Manager.

/**
 * Upon loading the object, if the location text isn't set, set it
 * @param \Doctrine\ORM\Event\LifecycleEventArgs $args
 */
public function postLoad(\Doctrine\ORM\Event\LifecycleEventArgs $args)
{
    $this->em = $args->getEntityManager();
    $entity = $args->getEntity();

    if ($entity instanceof \Entities\Location)
    {
        if (is_null($entity->getPathText()))
        {
            $entity->setPathText("new value");
            $this->em->flush($entity);
        }
    } elseif ($entity instanceof {parent Entity})
    {
        $location = $entity->getLocation();
        // This triggers the postLoad event again, but this time with Location as the parent Entity
        $this->em->initializeObject($location);
    }
}
