How to add an id automatically to a related entity

I have a OneToOne relation between 2 entities. One Molecule and one ConcGenotox (conclusion about genotoxicity).

I come from a page where all imformations about one Molecule are displayed and the id of the Molecule is in the address bar.

There is a button to edit a new ConcGenotox about this molecule witch id is always in the address bar.

My question is : How to add automatically the id from the molecule in the id_molecule relation of ConcGenotox when adding a new ConcGenotox ?

ConcGenotox Entity:

class ConcGenotox
{
    /**
     * @var \Molecule
     *
     * @ORM\OneToOne(targetEntity="Molecule")
     * @ORM\JoinColumns({
     *   @ORM\JoinColumn(name="id_molecule", referencedColumnName="id")
     * })
     *
     */
    private $idMolecule;

Molecule Entity :

class Molecule
{
   /**
    * @ORM\OneToOne(targetEntity="NcstoxBundle\Entity\ConcGenotox", mappedBy="idMolecule")
    */
   private $concGenotox;

Contrôler:

/**
 * Creates a new concGenotox entity.
 *
 * @Route("/new/{id}", name="concgenotox_new")
 * @Method({"GET", "POST"})
 */
public function newAction(Request $request, $id)
{
    $concGenotox = new Concgenotox();
    $form = $this->createForm('NcstoxBundle\Form\ConcGenotoxType', $concGenotox);
    $form->handleRequest($request);

    if ($form->isSubmitted() && $form->isValid()) {
        $em = $this->getDoctrine()->getManager();

        var_dump($id);
        $concGenotox->setIdMolecule($id);
        $em->persist($concGenotox);
        $em->flush();

        return $this->redirectToRoute('concgenotox_show', array('id' => $concGenotox->getId()));
    }

    return $this->render('concgenotox/new.html.twig', array(
        'concGenotox' => $concGenotox,
        'form' => $form->createView(),
        'id' => $id,
    ));
}

I tried to ->setIdMolecule($id) but it give me an error :

Expected value of type "NcstoxBundle\Entity\Molecule" for association field "NcstoxBundle\Entity\ConcGenotox#$idMolecule", got "string" instead.

Relationship property should be entity, not id.

Change:

class ConcGenotox
{
    /**
     * @var \Molecule
     *
     * @ORM\OneToOne(targetEntity="Molecule")
     * @ORM\JoinColumns({
     *   @ORM\JoinColumn(name="id_molecule", referencedColumnName="id")
     * })
     *
     */
    private $idMolecule;

to:

class ConcGenotox
{
    /**
     * @var \Molecule
     *
     * @ORM\OneToOne(targetEntity="Molecule", cascade={"persist"})
     */
    private $molecule;

and change your action to:

/**
 * Creates a new concGenotox entity.
 *
 * @Route("/new/{molecule}", name="concgenotox_new")
 * @Method({"GET", "POST"})
 */
public function newAction(Request $request, Molecule $molecule)
{
    $concGenotox = new Concgenotox();
    $form = $this->createForm(ConcGenotoxType::class);
    $form->handleRequest($request);

    if ($form->isSubmitted() && $form->isValid()) {
        $concGenotox = $form->getData();

        $molecule->setConcGenotox($concGenotox);

        $this->getDoctrine()->getManager()->flush();

        return $this->redirectToRoute('concgenotox_show', array('id' => $concGenotox->getId()));
    }

    return $this->render('concgenotox/new.html.twig', array(
        'concGenotox' => $concGenotox,
        'form'        => $form->createView(),
        'id'          => $id,
    ));
}

try this:

$em = $this->getDoctrine()->getManager();
$molecule = $em->getRepository('YourBundle:Molecule')
                    ->find($id);

$concGenotox->setIdMolecule($molecule);

You need to set the entity not the Id
