Symfony3 error with ManyToMany with attributes - symfony

Question

We have an error when trying to create a relationship within 2 tables like this
Llamadas -||--|<- LlamadaDerivada ->|--||- PersonaDerivada
And we are trying to create an only one create form with the "LlamadaDerivada" into it.
Inside Llamada entity
<?php
namespace xxxxBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
use Doctrine\Common\Collections\ArrayCollection;
class Llamada {
/**
* #var integer
*
* #ORM\Column(name="id", type="integer")
* #ORM\Id
* #ORM\GeneratedValue(strategy="SEQUENCE")
* #ORM\SequenceGenerator(sequenceName="llamada_id_seq", allocationSize=1, initialValue=1)
*/
private $id;
/**
* #var string
* #Assert\Length(
* max = 50,
* maxMessage = "Your first name cannot be longer than {{ limit }} characters",
* )
* #ORM\Column(name="nombre", type="string", length=150, nullable=false)
*/
private $nombre;
/**
*
* #ORM\OneToMany(targetEntity="LlamadaDerivado", mappedBy="llamada")
*/
private $derivados;
function __construct() {
$this->derivados = new ArrayCollection();
}
function getId() {
return $this->id;
}
function getNombre() {
return $this->nombre;
}
function setId($id) {
$this->id = $id;
}
function setNombre($nombre) {
$this->nombre = $nombre;
}
function getDerivados(){
return $this->derivados;
}
function setDerivados($derivados){
$this->derivados = $derivados;
}
}
Then inside LlamadaDerivado Entity we have this
<?php
namespace xxxBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
/**
* LlamadaDerivado
*
* #ORM\Table(name="llamada_derivado")
* #ORM\Entity
*/
class LlamadaDerivado
{
/**
* #var \AgendaBundle\Entity\Llamada
*
* #ORM\ManyToOne(targetEntity="AgendaBundle\Entity\Llamada",inversedBy="derivados",cascade={"persist"})
* #ORM\Id
* #ORM\JoinColumns({
* #ORM\JoinColumn(name="id_llamada", referencedColumnName="id")
* })
*/
private $llamada;
/**
* #var \AgendaBundle\Entity\PersonaDerivado
*
* #ORM\ManyToOne(targetEntity="AgendaBundle\Entity\PersonaDerivado",inversedBy="llamadas",cascade={"persist"})
* #ORM\Id
* #ORM\JoinColumns({
* #ORM\JoinColumn(name="id_derivado", referencedColumnName="id")
* })
*/
private $derivado;
/**
* #var DateTime
*
* #ORM\Column(name="fecha_derivacion", type="date", nullable=false)
*/
private $fechaDerivacion;
function getLlamada(){
return $this->llamada;
}
function getDerivado(){
return $this->derivado;
}
function getFechaDerivacion() {
return $this->fechaDerivacion;
}
function setLlamada( $llamada) {
$this->llamada = $llamada;
}
function setDerivado( $derivado) {
$this->derivado = $derivado;
}
function setFechaDerivacion($fechaDerivacion) {
$this->fechaDerivacion = $fechaDerivacion;
}
}
And inside PersonaDerivado entity
<?php
namespace xxxBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
use Doctrine\Common\Collections\ArrayCollection;
/**
* ReunionLugar
*
* #ORM\Table(name="persona_derivado")
* #ORM\Entity
*/
class PersonaDerivado
{
public function __construct() {
$this->llamadas = new ArrayCollection();
}
/**
* #var integer
*
* #ORM\Column(name="id", type="integer")
* #ORM\Id
* #ORM\GeneratedValue(strategy="SEQUENCE")
* #ORM\SequenceGenerator(sequenceName="reunion_lugar_id_seq", allocationSize=1, initialValue=1)
*/
private $id;
/**
* #var string
*
* #ORM\Column(name="nombre", type="string", length=150, nullable=false)
*/
private $nombre;
/**
* #ORM\OneToMany(targetEntity="LlamadaDerivado", mappedBy="derivado")
*/
private $llamadas;
function getId() {
return $this->id;
}
function getNombre() {
return $this->nombre;
}
function setId($id) {
$this->id = $id;
}
function setNombre($nombre) {
$this->nombre = $nombre;
}
function setLlamadas($llamadas) {
$this->llamadas = $llamadas;
}
}
And the LlamadaType is
class LlamadaDto extends AbstractType {
public function buildForm(FormBuilderInterface $builder, array $options) {
$disabled = $options['disabled'];
$builder
->add('id', HiddenType::class)
->add('nombre', TextType::class, array(
'disabled' => $disabled,
'attr' => ['maxlength'=>'50']
))->add('apellido', TextType::class, array(
'disabled' => $disabled,
'attr' => ['maxlength'=>'50']
))->add('fecha', DateType::class, array(
'format' => 'dd/MM/yyyy',
'disabled' => $disabled,
'widget' => 'single_text',
'attr' => ['class' => 'datepicker']
))->add('hora', TimeType::class, array(
'disabled' => $disabled
))->add('motivo', TextareaType::class, array(
'disabled' => $disabled,
'attr' => ['maxlength'=>'400']
))->add('telefonoContacto', TextType::class, array(
'disabled' => $disabled,
'attr' => ['maxlength'=>'9']
))->add('derivados', EntityType::class, array(
'class' => 'AgendaBundle:PersonaDerivado',
'choice_label' => 'apellidoNombre',
'placeholder' => 'Seleccionar un derivado',
'multiple' => true,
));
}
public function configureOptions(OptionsResolver$resolver) {
$resolver->setDefaults(array('data_class' => Llamada::class));
}
}
Inside the controller we have this code
<?php
/**
* #Route("/Llamada/save",name="saveLlamada")
*/
public function saveLlamadaAction(Request $request) {
$llamadaService = $this->get('llamadaService');
$derivadoService = $this->get('derivadoService');
$form = $this->createForm(LlamadaDto::class);
$form->handleRequest($request);
$editar = TRUE;
$llamada = $form->getData();
$derivados = $request->request->get("llamada_dto")["derivados"];
$derivadosActuales = $derivadoService->getLlamadaDerivados($llamada->getId());
foreach ($derivados as $key1 => $d) {
foreach ($derivadosActuales as $key2 => $da) {
if($da->getDerivado()->getId()==$d){
array_splice($derivados, array_search($d, $derivados),1);
}
}
}
if ($llamadaService->saveLlamada($llamada)) {
$this->addFlash(
'exitoLlamada', 'Datos de llamada guardados exitosamente'
);
$derivadoService->saveDerivados($derivados,$llamada);
} else {
$this->addFlash(
'errorLlamada', 'Disculpe, hubo un error en el registro de la llamada'
);
}
return new RedirectResponse($this->generateUrl('listaLlamadas', array(), UrlGeneratorInterface::RELATIVE_PATH));
}
And the services called are this ones:
public function saveLlamada($llamada ){
try{
if($llamada->getId()){
$this->em->merge($llamada);
}else{
$this->em->persist($llamada);
}
$this->em->flush();
return TRUE;
} catch (Exception $ex){
return FALSE;
}
}
public function saveDerivados($derivados,$llamada){
foreach ($derivados as $key => $derivado) {
$llamadaDerivado = new LlamadaDerivado();
$personaLlamada = $this->getDerivado($derivado);
$llamadaDerivado->setLlamada($llamada);
$llamadaDerivado->setDerivado($personaLlamada);
$llamadaDerivado->setFechaDerivacion(new \DateTime('now', (new \DateTimeZone('America/Argentina/Ushuaia'))));
$this->em->persist($llamadaDerivado);
$this->em->flush();
}
}
This is the error that we are getting:
Uncaught PHP Exception Doctrine\ORM\ORMInvalidArgumentException: "Expected value of type "Doctrine\Common\Collections\Collection|array" for association field "xxxBundle\Entity\Llamada#$derivados", got "xxxBundle\Entity\PersonaDerivado" instead." at project\vendor\doctrine\orm\lib\Doctrine\ORM\ORMInvalidArgumentException.php line 206
We've been 1 week with this.
Many thanks in advance

Answer 1

You can try to use a CollectionType instead of EntityType in your formtype, although I have a piece of code in front of me that works just fine with EntityType and the multiple flag for a OneToMany relationship.

Answer 2

look at Llamada entity, $derivados is an array collection of LlamadaDerivado and in your LlamadaType you make it entityType of AgendaBundle:PersonaDerivado, that is why you got this error. Think to use Collection Type to add everytime all the object LlamadaDerivado to well respect the mapping.
