Symfony - Error deserializing json from objects with relationships

Question

Using SF 2.8 and serializer component.

I have 2 entities with relationships many to one.

ENTITY USUARIO

...
class Usuario implements UserInterface
{
...
/**
 * @var int
 *
 * @ORM\Column(name="id", type="integer")
 * @ORM\Id
 * @ORM\GeneratedValue(strategy="AUTO")
 */
protected $id;

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

/**
 * @var string
 *
 * @ORM\Column(name="apellidos", type="string", length=100)
 */
private $apellidos;

...getters and setters...

ENTITY PLAN

...
class Plan
{
/**
 * @var int
 *
 * @ORM\Column(name="id", type="integer")
 * @ORM\Id
 * @ORM\GeneratedValue(strategy="AUTO")
 */
private $id;

/**
 * @ORM\ManyToOne(targetEntity="\UsuariosBundle\Entity\Usuario", cascade={"persist"})
 * @ORM\JoinColumn(name="usuario_id", referencedColumnName="id", onDelete="CASCADE")
 */
private $usuario;

/**
 * @var array
 *
 * @ORM\Column(name="json_dieta", type="json_array")
 */
private $jsonDieta;

...getters and setters...

As you can see, property $usuario (entity plan) is joined with $id (entity usuario).

My intention is to save a json in a field of the table plan of the DB to recover the data when I need them; for do that, first I have to serialize the data and save the to the DB (DONE!) but when I have to deserialize them for recovering the data and transform them to objects I get this error:

Type error: Argument 1 passed to ComponentesBundle\Entity\Receta::setUsuario() must be an instance of UsuariosBundle\Entity\Usuario, array given, called in C:\xampp7\htdocs\Dietas\vendor\symfony\serializer\Normalizer\GetSetMethodNormalizer.php on line 118

MY CONTROLLER

...
$em = $this->getDoctrine()->getManager();

    $plan =$em->getRepository('UsuariosBundle:Plan')->findOneByUsuario($user->getId());

    $serializer = new Serializer(
        array(new GetSetMethodNormalizer(), new ArrayDenormalizer()),
        array(new JsonEncoder())
        );
    $jsonDeserializado = $serializer->deserialize($plan->getJsonDieta(), 'ComponentesBundle\Entity\Receta[][][]', 'json');
    dump($jsonDeserializado);
...

Any idea how can I solve this?

First you can view here how to should be looks like correct entity and mapping for one to many bidirectional: Relationships in Doctrine And after that you use serializer anotation strategy inside entity or you can create mapping strategy for serializer what propery to serialize and which does not

thanks for your response; in this case I use unidirectional relationship and I have checked it and I think it is OK; Using annotation for groups could be a solution if I would want avoid to serialize or deserialize the conflictive property but I need to convert the complete json like the entire object – viejalospelos Apr 10 '18 at 14:29
Okey, I uderstand, But I will recommend you to use http://jmsyst.com/bundles/JMSSerializerBundle – l13 Apr 10 '18 at 16:43
