Use service in entity - php

Question

I need to use a service in one of my entities but I don't know how to get the container. My attributes $numHeure and $numSem are conversions of $dateDebut.
<?php
namespace Agnez\CoreBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
/**
* EdtHeure
*
* #ORM\Table(name="agnez_edt_heure")
* #ORM\Entity(repositoryClass="Agnez\CoreBundle\Repository\EdtHeureRepository")
*/
class EdtHeure
{
/**
*#var datetime
*#ORM\Column(type="datetime", name="dateDebut")
*/
private $dateDebut;
/**
*#var int
*#ORM\Column(type="int", name="numHeure")
*/
private $numHeure;
/**
*#var int
*#ORM\Column(type="int", name="numSem")
*/
private $numSem;
/**
* Set dateDebut
*
* #param \DateTime $dateDebut
*
* #return EdtHeure
*/
public function setDateDebut($dateDebut)
{
$this->dateDebut = $dateDebut;
$servicedate = $this->container->get('agnez_core.servicedate');
$this->numSem=$servicedate->numSem($date);
$this->numHeure=$servicedate->numHeure($date);
return $this;
}
}
I got the error:
Notice: Undefined property:
Agnez\CoreBundle\Entity\EdtHeure::$container

Answer 1

I don't think you need a service in your entity, and you should avoid it.
1) You can use a doctrine Event [documentation]
public function __construct(ServiceDate servicedate)
{
$this->servicedate = $servicedate
}
public function postUpdate(LifecycleEventArgs $args)
{
$entity = $args->getEntity();
if (!$entity instanceof EdtHeure) {
return;
}
$entityManager = $args->getEntityManager();
// Call your service here
}
2) An other way is to call the service outside your entity
public function setDateDebut($dateDebut, $numSem, $numHeure)
And to call it outside, in a service EdtHeureUpdater. Its responsability will be to call various needed services and made change to your entity.
public function __construct(ServiceDate servicedate)
{
$this->servicedate = $servicedate
}
public function updateHeure(EdtHeure $edt, \DateTime $date)
{
$numSem = $this->servicedate->numSem($date);
$numHeure = $this->servicedate->numHeure($date)
$edt->setDateDebut($dateDebut, $numSem, $numHeure)
}
