Symfony find field - php

Question

I have a Developers entity and table named CodeUserReference
class CodeUserReference
{
/**
* #var integer
*
* #ORM\Column(name="id", type="integer")
* #ORM\Id
* #ORM\GeneratedValue(strategy="AUTO")
*/
protected $id;
/**
*#ORM\ManyToOne(targetEntity="Artel\CustomerBundle\Entity\Developers", inversedBy="newreference")
*/
protected $alluser;
/**
* #ORM\Column(type="string", length=255)
*/
protected $codereference;
and Developers
class Developers extends SUser
{
/**
* #var string
*
* #ORM\Column(name="email", type="string", length=255, unique=false, nullable=false)
* #Assert\Length(min=3, max=255)
* #Assert\NotBlank
*/
protected $email;
/**
* #ORM\ManyToMany(targetEntity="Artel\CustomerBundle\Entity\CodeUserReference", inversedBy="alluser")
*/
protected $newreference;
I have get query in my Action
public function profileGetAction(Request $request)
{
$em = $this->getDoctrine()->getManager();
$code_user_reference = $em->getRepository('ArtelCustomerBundle:CodeUserReference')->findOneByCodereference($request->query->get('reference'));
$user_by_email = $em->getRepository('ArtelCustomerBundle:Developers')->findOneByEmail($request->query->get('email'));
if (!empty($code_user_reference) && empty($user_by_email))
{
$id = $code_user_reference->getAlluser()->getId();
$user_by_reference = $em->getRepository('ArtelCustomerBundle:Developers')->findOneById($id);
$user_by_reference_json = $em->getRepository('ArtelCustomerBundle:Developers')->createQueryBuilder('d')
->where('d.id= :id')
->groupBy('d.id')
->setParameter('id', $code_user_reference->getAlluser()->getId())
->getQuery()->getArrayResult();
echo json_encode( array('user' => $user_by_reference_json));
die;
}
If(empty($code_user_reference) && !empty($user_by_email))
.......
I get Id in code_user_reference, then I find Developers objects with this ID, then I create a QueryBuilder and in this QueryBuilder I find the developers objects again, for JSON table. I find this very hard, who knows easier practics ?

There is certanly mismapping.
if you have #ORM\ManyToOne from one site, there should be #ORM\OneToMany from other.
Or, if you need many-to-many relationship, there should be #ORM\ManyToMany on both entities.
Also, relation should be mapped at one side. If you have (targetEntity="Artel\CustomerBundle\Entity\Developers", inversedBy="newreference") it means it should be mapped here
something like
#ORM\ManyToOne(targetEntity="Artel\CustomerBundle\Entity\Developers", inversedBy="newreference")
#ORM\JoinColumn(name="id_developer", referencedColumnName="id")
and at the other side must be mappedBy instead of inversedBy
* #ORM\OneToMany(targetEntity="Artel\CustomerBundle\Entity\CodeUserReference", mappedBy="alluser")
