Sonata admin with a2lix_translatable. How to do relationships? - symfony

Question

I want to create table Pracownik which can contain zero or few instances of Zaklady and control it using Sonata Admin. Both of tables are translated using a2lix_translatable.
So I have classes:
<?php
namespace JCuryllo\InstituteBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
use Knp\DoctrineBehaviors\Model as ORMBehaviors;
/**
* Pracownik
*
* #ORM\Table()
* #ORM\Entity
*/
class Pracownik
{
use ORMBehaviors\Translatable\Translatable;
public function __call($method, $arguments)
{
return $this->proxyCurrentLocaleTranslation($method, $arguments);
}
/**
* #ORM\ManyToOne(targetEntity="ZakladyTranslation")
**/
private $zaklady;
/**
* #var integer
*
* #ORM\Column(name="id", type="integer")
* #ORM\Id
* #ORM\GeneratedValue(strategy="AUTO")
*/
private $id;
/**
* and other properties
*/
/**
* Get id
*
* #return integer
*/
public function getId()
{
return $this->id;
}
/* and other getters and setter */
}
And Translation:
<?php
namespace JCuryllo\InstituteBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
use Knp\DoctrineBehaviors\Model as ORMBehaviors;
/**
* #ORM\Entity
*/
class PracownikTranslation
{
use ORMBehaviors\Translatable\Translation;
public function __toString()
{
return $this->getTitle();
}
/**
* #var string
*
* #ORM\Column(name="name", type="string", length=255)
*/
private $name;
/* and other properties */
/**
* Set name
*
* #param string $name
* #return Pracownik
*/
public function setName($name)
{
$this->name = $name;
return $this;
}
/**
* Get name
*
* #return string
*/
public function getName()
{
return $this->name;
}
/* and other getters and setter *.
}
I've used very similar code in Zaklady and ZakladyTranslation. Then in PracownikAdmin I try to do sth like:
protected function configureFormFields(FormMapper $formMapper)
{
$formMapper
->add('zaklady', 'many_to_one',array(
'required' => false,
))
->add('translations', 'a2lix_translations')
;
}
but it doesn't work (error: Could not load type "many_to_one").

Answer 1

many_to_one is not an available form type for Sonata, you have to use sonata_type_model or sonata_type_model_list for a many to one relation.
Example:
protected function configureFormFields(FormMapper $formMapper)
{
$formMapper
->add('zaklady', 'sonata_type_model_list',array(
'required' => false,
))
->add('translations', 'a2lix_translations');
}

Answer 2

Ok, I have done it.
In Zaklady I added:
public function __toString()
{
return $this->getTitle(); // getTitle is in ZakladyTranslation!
}
In Pracownik I changed:
/**
* #ORM\ManyToOne(targetEntity="ZakladyTranslation")
**/
private $zaklady;
to:
/**
* #ORM\ManyToOne(targetEntity="Zaklady")
**/
private $zaklady;
and PracownikAdmin:
protected function configureFormFields(FormMapper $formMapper)
{
$formMapper
->add('translations', 'a2lix_translations')
->add('zaklady', 'sonata_type_model', array(
'multiple' => true,
'by_reference' => false,
'required' => false
))
;
}
