Doctrine 2 entity caching while persisting - php

Question

I am having an issue with Doctrine 2 and can not find a solution for it. It seems that when persisting an entity (and flushing it). When trying to search for it in DB using the assigned id while within the same PHP process doctrine is giving me the cached version of the entity instead of building a proper one with all correct relations. My problem with that is that my entity has some Many to many or many to one connections and if i get the the cached version all those properties come back as null instead of an instance of \Doctrine\Common\Collections\Collection.
Is there any way I can force doctrine to generate or update my entity to assign all those connections, or at least force it to serch for that entity insead of giving it to me from cache?
As requested examples:
class A extends AbstractDoctrineEntity {
/**
* #var int
* #ORM\Id
* #ORM\GeneratedValue(strategy="AUTO")
* #ORM\Column(type="integer")
*/
protected $id;
/**
* #var \Core\Entity\B
* #ORM\ManyToOne(targetEntity="Core\Entity\B")
*/
protected $relationB;
/**
* #var \Doctrine\Common\Collections\Collection
* #ORM\ManyToMany(targetEntity="Core\Entity\C", inversedBy="relationA", fetch="EXTRA_LAZY")
*
*/
protected $relationC;
//getters and setters
}
class B extends AbstractDoctrineEntity {
/**
* #var int
* #ORM\Id
* #ORM\GeneratedValue(strategy="AUTO")
* #ORM\Column(type="integer")
*/
protected $id;
/**
* #var \Core\Entity\A
* #ORM\OneToMany(targetEntity="Core\Entity\A")
*/
protected $relationA;
//getters and setters
}
class B extends AbstractDoctrineEntity {
/**
* #var int
* #ORM\Id
* #ORM\GeneratedValue(strategy="AUTO")
* #ORM\Column(type="integer")
*/
protected $id;
/**
* #var \Core\Entity\A
* #ORM\ManyToMany(targetEntity="Core\Entity\A", mappedBy="realtionC", cascade={"persist", "remove")
*/
protected $relationA;
//getters and setters
}
// Service
class SomeService implements ServiceLocatorAwareInterface, MultiRepositoryServiceInterface {
use ServiceLocatorAwareTrait, MultiRepositoryServiceTrait;
public function createA(\Core\Entity\B $b) {
$a = new \Core\Entity\A();
$a->setB($b);
$this->getRepository('a')->persist($a); // gets entity manager persists entity $a and flushes
return $a;
/**
* returns an object
* a = {
* id = 2,
* relationB = Core\Entity\B,
* ralationC = null,
*/
}
}
public function getA($id){
$a = $this->getRepository('a')->persist($a); // retrieves object manager and queries by id;
return $a;
//**
* returns an object
* a = {
* id = 2,
* relationB = Core\Entity\B,
* ralationC = \Doctrine\Common\Collections\Collection, //which is an empty collection prototype and exactly what i need to retrieve in the first case when persisting the entity.
* }
*/
}
}
EDIT:
Found a solution, this may not be the nicest way to do this, so if someone knows a better way please update, but for now it works:
-----
public function createA(\Core\Entity\B $b) {
$a = new \Core\Entity\A();
$a->setB($b);
$this->getRepository('a')->persist($a); // gets entity manager persists entity $a and flushes
$this->getRepository('a')->detatch($a); // removes entity from management
return $this->getRepository('a')->find($a->getId());
/**
* returns an object
* a = {
* id = 2,
* relationB = Core\Entity\B,
* ralationC = \Doctrine\Common\Collections\Collection,
*/
}
}
----
This has a downside of re-querying after detachment and has a negative performance impact. If someone knows of a better solution it would be much appreciated.
