ZF2 Doctrine2 : How to implement form with relation? - doctrine-orm

Question

I have found a tutorial to implement a form with entities annotations.
Doctrine entity with zend form
I want to know how to implement with a relation.
This is my code...
My entity :
/**
* Account
*
* #ORM\Table(name="account", indexes={#ORM\Index(name="IDX_7D3656A4C6798DB", columns={"account_type_id"})})
* #ORM\Entity(repositoryClass="Application\Repository\Account")
* #Annotation\Name("account")
*/
class Account extends EntityAbstract implements InputFilterAwareInterface, UserInterface
{
/**
* #var Zend\InputFilter\InputFilter
*/
protected $inputFilter;
/**
* #var integer
*
* #ORM\Column(name="id", type="bigint", nullable=false, options={"input" = "hidden"})
* #ORM\Id
* #ORM\GeneratedValue(strategy="SEQUENCE")
* #ORM\SequenceGenerator(sequenceName="account_id_seq", allocationSize=1, initialValue=1)
* #Annotation\Attributes({"type":"hidden"})
*/
protected $id;
/**
* #var string
*
* #ORM\Column(name="code", type="string", nullable=false, unique=true, options={"input" = "text"})
* #Annotation\Attributes({"type":"text", "class":"test"})
* #Annotation\Options({"label":"Code"})
*/
protected $code;
/**
* #var string
*
* #ORM\Column(name="password", type="string", nullable=false, options={"input" = "password"})
* #Annotation\Attributes({"type":"text"})
* #Annotation\Options({"label":"Mot de passe"})
*/
protected $password;
/**
* #var string
*
* #ORM\Column(name="password_key", type="string", nullable=false, options={"input" = "password"})
* #Annotation\Exclude()
*/
protected $passwordKey;
/**
* #var boolean
*
* #ORM\Column(name="active", type="boolean", nullable=false, options={"input" = "checkbox"})
* #Annotation\Attributes({"type":"checkbox"})
* #Annotation\Options({"label":"Actif"})
*/
protected $active = false;
/**
* #var string
*/
protected $displayName;
/**
* #var boolean
*
* #ORM\Column(name="visible", type="boolean", nullable=false, options={"input" = "checkbox"})
* #Annotation\Attributes({"type":"checkbox"})
* #Annotation\Options({"label":"Visible"})
*/
protected $visible = false;
/**
* #var \DateTime
*
* #ORM\Column(name="start_date", type="datetime", nullable=false, options={"input" = "date"})
* #Annotation\Attributes({"type":"date"})
* #Annotation\Options({"label":"Date de début"})
*/
protected $startDate = 'now()';
/**
* #var \DateTime
*
* #ORM\Column(name="end_date", type="datetime", nullable=true, options={"input" = "date"})
* #Annotation\Attributes({"type":"date"})
* #Annotation\Options({"label":"Date de fin"})
*/
protected $endDate;
/**
* #var string
*
* #ORM\Column(name="token", type="string", nullable=false, options={"input" = "password"})
* #Annotation\Exclude()
*/
protected $token;
/**
* #var integer
*
* #ORM\Column(name="expires", type="integer", nullable=true)
* #Annotation\Exclude()
*/
protected $expires;
/**
* #var \Application\Entity\AccountType
*
* #ORM\ManyToOne(targetEntity="Application\Entity\AccountType", fetch="EAGER", inversedBy="accounts")
* #ORM\JoinColumns({
* #ORM\JoinColumn(name="account_type_id", referencedColumnName="id", nullable=false)
* })
* #Annotation\Type("DoctrineModule\Form\Element\ObjectSelect")
* #Annotation\Options({"label":"Type de compte", "object_manager":"Doctrine\Common\Persistence\ObjectManager" ,"target_class":"Application\Entity\AccountType"})
*/
protected $accountType;

My controller edit action :
public function editAction()
{
try
{
$entityManager = $this->getEntityManager();
$repository = $this->getRepository();
$id = (int)$this->params()->fromRoute('id');
$user = $repository->find($id);
$builder = new AnnotationBuilder($entityManager);
$form = $builder->createForm($user);
$form->setHydrator(new DoctrineHydrator($entityManager,'Application\Entity\Account'));
$form->bind($user);
$view = new ViewModel();
$view->setVariable('form', $form);
return $view;
}
catch(\Exception $e)
{
echo '<pre>';
print_r($e->getMessage());
echo '</pre>';
}
}
I catch this error :
Catchable fatal error: Argument 1 passed to DoctrineModule\Form\Element\Proxy::setObjectManager() must implement interface Doctrine\Common\Persistence\ObjectManager, string given, called in /Users/thibaud/Sites/api/vendor/doctrine/doctrine-module/src/DoctrineModule/Form/Element/Proxy.php on line 86 and defined in /Users/thibaud/Sites/api/vendor/doctrine/doctrine-module/src/DoctrineModule/Form/Element/Proxy.php on line 185
Ok. I know how relations works and how to build a form with doctrine with relations but don't know how to implement the same with anotations. Here is how i build form with a relation :
$this->add
(
array
(
'name' => 'accountType',
'type' => 'DoctrineModule\Form\Element\ObjectSelect',
'options' => array
(
'label' => 'Type de compte',
'object_manager' => $this->getObjectManager(),
'target_class' => 'Application\Entity\AccountType',
'label_generator' => function($target)
{
return $target->getName();
}
),
)
);

Answer 1

use Zend\Form\Annotation as Form;
/**
*
* #Form\Type("DoctrineModule\Form\Element\ObjectSelect")
* #Form\Attributes({"required":"required"})
* #Form\Required(true)
* #Form\Options({
* "label":"Account",
* "empty_option": "Please choose",
* "target_class": "Application\Entity\Whatever",
* "property": "CoolProperty",
* "find_method": {
* "name": "findBy",
* "params": {
* "criteria": {"awesomeCriteria": 0},
* "orderBy": {"letsSayDate": "ASC"}
* }
* }
* })
*/
For clarity and shorter codes sake I gave the namespace a alias called Form.
