sonata: Dealing with sonata_type_model (one-to-many)

Question

1- I have an Entity:

EmployeeMedicalService

/**
 * @ORM\Entity
 * @ORM\Table(name="employee_medical_file")
 */
class EmployeeMedicalService extends BaseEntity
{

   //
   // Some
   // Fields
   //


    /**
     * @Assert\NotBlank
     * @ORM\ManyToOne(targetEntity="PersonnelBundle\Entity\Lookup\Lookup")
     * @ORM\JoinColumn(name="medical_service_id", referencedColumnName="id")
     */
    private $medicalService;

   //
   // getters
   // & setters
   //

---

2- Another Entity:

Lookup

/**
 * @ORM\Entity
 * @ORM\Table(name="lookup")
 * @UniqueEntity(fields="name")
 */
class Lookup extends BaseEntity
{
    // const ...
    const TYPE_MEDICAL_SERVICE = 'medical_service';
    // more constants ...

    public function __construct($type)
    {
        $this->type = $type;
    }

     //
     // Some Fields
     //

    /**
     * @var string
     * --stuff--
     */
    private $name;

    /**
     * @var string
     * 
     * @ORM\Column(name="type", type="string", length=50)
     * @Assert\NotBlank
     */
    private $type;

    //getters
    // &setters

---

Now in the

EmployeeMedicalServiceAdmin

protected function configureFormFields(\Sonata\AdminBundle\Form\FormMapper $formMapper)
    {

        $msquery = $this->getModelManager()
                ->getEntityManager('PersonnelBundle:Lookup\Lookup')
                ->createQueryBuilder();

        $msquery->select('l')->from('PersonnelBundle:Lookup\Lookup', 'l')->where('l.type = :type')
                ->orderBy('l.name', 'ASC')
                ->setParameter('type', 'medical_service');

        $formMapper
                ->add(..)

                ->add('medicalService', 'sonata_type_model', array(
                    'label' => 'personnel.employee.medical_service.form.medical_service',
                    'property' => 'name',
                    'placeholder' => '',
                    'required' => false,
                    'query' => $msquery,
                ))

                ->add(..)
        ;
    }

** My Problem: **

I need the form for add new lookup(medical service) from inside the EmployeeMedicalService Admin Form to be preloaded with the field Type value set to 'medical_service' When I attempt to add a new Medical Service from inside the EmployeeMedicalService Admin Form or else a new lookup is added without the value if Type set to NULL

---

This is the

LookupAdmin

protected function configureFormFields(FormMapper $formMapper)
    {
        $formMapper
                ->add('name', 'text', array(
                    'label' => 'personnel.lookup.form.name'
                ))
                ->add('type', 'hidden', array(
                    'label' => 'personnel.lookup.form.type',
                ))
        ;
    }

Answer 1

If you inspect ajax request for the popup form you will notice extra query parameters, such as pcode. You could check if this parameter exists and equals EmployeeMedicalServiceAdmin admin class code then set lookup type to medical_service.

UPDATE

Add this king of logic in the getNewInstance() method:

public function getNewInstance()
{
    $type = isset($_GET['pcode']) ? 'medical_service' : '';
    $instance = new \PersonnelBundle\Entity\Employee\EmployeeMedicalService($type);

    return $object;
}
