Symfony Error when trying to get data in a relationship - php

Question

Symfony is tormenting my head right now. I'm trying to get data from a table where the column associates a relationship with an id from another table. Thats my controller function:
/**
* #Route("/proposta/{id}", defaults={"id"=null})
*/
public function mostraAction($id) {
$model = $this->getDoctrine()->getManager();
$lista = $model->getRepository('AppBundle:Propostes')->find($id);
$em = $this->getDoctrine()->getManager();
$listaVotacions = $em->getRepository('AppBundle:Votacions')->findByIdProposta($id);
return $this->render(':Proposta:index.html.php',
array('lista'=>$lista,'listaVotacions'=>$listaVotacions));
}
That's not working, when I execute this function, my server falls and I get this error:
[ERROR] Built-in server terminated unexpectedly.
That's my class of Votacions:
<?php
namespace AppBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
/**
* Votacions
*
* #ORM\Table(name="votacions")
* #ORM\Entity(repositoryClass="AppBundle\Repository\VotacionsRepository")
*/
class Votacions
{
/**
* #var int
*
* #ORM\Column(name="id", type="integer")
* #ORM\Id
* #ORM\GeneratedValue(strategy="AUTO")
*/
private $id;
/**
* #ORM\ManyToOne(targetEntity="Propostes")
*/
private $idProposta;
/**
* #ORM\ManyToOne(targetEntity="Usuaris")
*/
private $idUsuari;
/**
* #var bool
*
* #ORM\Column(name="vot", type="boolean", nullable=true)
*/
private $vot;
/**
* Get id
*
* #return int
*/
public function getId()
{
return $this->id;
}
/**
* Set idProposta
*
* #param integer $idProposta
*
* #return Votacions
*/
public function setIdProposta($idProposta)
{
$this->idProposta = $idProposta;
return $this;
}
/**
* Get idProposta
*
* #return int
*/
public function getIdProposta()
{
return $this->idProposta;
}
/**
* Set idUsuari
*
* #param integer $idUsuari
*
* #return Votacions
*/
public function setIdUsuari($idUsuari)
{
$this->idUsuari = $idUsuari;
return $this;
}
/**
* Get idUsuari
*
* #return int
*/
public function getIdUsuari()
{
return $this->idUsuari;
}
/**
* Set vot
*
* #param boolean $vot
*
* #return Votacions
*/
public function setVot($vot)
{
$this->vot = $vot;
return $this;
}
/**
* Get vot
*
* #return bool
*/
public function getVot()
{
return $this->vot;
}
}
And this my repository Votacions:
namespace AppBundle\Entity;
use Doctrine\ORM\EntityRepository;
class VotacionsRepository extends EntityRepository
{
public function findByIdProposta($id)
{
return $this->getEntityManager()
->createQuery(
'SELECT * FROM AppBundle:Votacions WHERE idProposta ='.$id
)->getResult();
}
}
Someone could help me :(?
Thank you so much.

Call only one time the "GetDoctrine"
-> find your lista object
-> Access idProposta from $lista object
-> the id from Proposta Entity
public function mostraAction($id) {
$model = $this->getDoctrine()->getManager();
$lista = $model->getRepository('AppBundle:Votacions')->find($id);
$lista->getIdProposta()->getId();
//..
return $this->render(':Proposta:index.html.php',
array('lista'=>$lista,'listaVotacions'=>$listaVotacions));
}
