default value for entity widget in a formbuilder - forms

Question

I have seen a lot of topics concerning how to set default data on a form in Symfony2, but I didn't find anything about how to set default data in an entity widget with a query builder. I explain my problem :
I have two entities, communication and Status, with a relation ManyToOne.
Here is my Communication class :
class Communication{
/**
* #ORM\Id
* #ORM\Column(name="Comm_CommunicationId")
* #ORM\Column(type="integer")
* #ORM\GeneratedValue(strategy="IDENTITY")
*/
protected $id;
/**
* #ORM\ManyToOne(targetEntity="Test\DatabaseBundle\Entity\Statut", inversedBy="communication")
* #ORM\JoinColumn(name="Comm_Status", referencedColumnName="Capt_Code")
*/
private $statut;}
And here is my Status class:
class Statut{
/**
* #ORM\Id
* #ORM\Column(name="Capt_CaptionId")
* #ORM\Column(type="integer")
* #ORM\GeneratedValue(strategy="IDENTITY")
*/
protected $id;
/**
* #ORM\Column(name="Capt_Code", type="string")
*/
private $code;
/**
* #ORM\Column(name="Capt_FR", type="string")
*/
private $codefr;}
I have built a CommunicationType form to allow me to modify a communication entity:
public function buildForm(FormBuilder $builder, array $options)
{
$builder -> add('caseid','text')
-> add('statut','entity', array('class' => 'Test\DatabaseBundle\Entity\Statut',
'query_builder' => function(\Test\DatabaseBundle\Entity\StatutRepository $sr){
$res = $sr->getCodeOnly();
return $res; },
'property' => 'CodeFr',
'preferred_choices' => array(1),
));}
Here is my controller:
public function ModifierAction($commid){
$comm = $this -> getDoctrine()
-> getEntityManager()
-> getRepository('Test\DatabaseBundle\Entity\Communication')
-> find($commid);
$form = $this -> createForm(new CommunicationType($em), $comm);
....
}
I give you the setter and the getter of my entities :
communication :
/**
* Set id
*
* #param integer $Id
*/
public function setId($Id)
{
$this -> id = $Id;
}
/**
* Get id
*
* #return integer
*/
public function getId()
{
return $this->id;
}
Status entity :
/**
* Set id
*
* #param integer $id
*/
public function setId($id)
{
$this->id = $id;
}
/**
* Get id
*
* #return integer
*/
public function getId()
{
return $this->id;
} /**
* Set code
*
* #param string $code
*/
public function setCode($code)
{
$this->code = $code;
}
/**
* Get code
*
* #return string
*/
public function getCode()
{
return $this->code;
} /**
* Add communication
*
* #param Acme\StoreBundle\Entity\Communication $communication
*/
public function addCommunication(\Test\DatabaseBundle\Entity\Communication $communication)
{
$this->communication[] = $communication;
}
/**
* Get communication
*
* #return Doctrine\Common\Collections\Collection
*/
public function getCommunication()
{
return $this->ccommunication;
} public function __construct()
{
$this->communication = new ArrayCollection();
}
you said doctrine automatically check the object. Do you that , normally, doctrine execute the query and search, in the database, the current value of the object and pass it as the default choice?
With this I can modify my entity, but I don't know how to put my current entity Status value as the default value for the widget "entity". The method "getCodeOnly" search in the database the value of the attibut code of status (Complete, Cancelled, InProgress, Deleted) and always passed Complete as the default value. For exemple, if an entity as the value Cancelled, I want to put Cancelled as the default value when I use this form to modify my entity.
I cannot use getData and preferred_choice to have access to the status value because preferred_choice needs an array as parameter and not an entity.
I also tried to build an array with the different values of status and passed it to my form but du to several problem with my database, it failed.
If anyone have any infomation to solve this problem, i would be happy to see it.
