POValidation error on ManyToMany form
text
Body
copied!<p>I want to build a form to store some data. A "Tarea" could have many "Material" and a "Material" coul belong to one or more "Tarea". The "Material" entity has a image property, with picture upload.</p> <p>I can create a new "Material" with a picture with no problem. The problem becomes when I tried to create a new "Tarea", when I submit the form, I´m getting "The file could not be found" error.</p> <p>This is my Material entity with the file upload function:</p> <pre><code>/** * Gitek\HotelBundle\Entity\Material * * @ORM\Table() * @ORM\Entity(repositoryClass="Gitek\HotelBundle\Entity\MaterialRepository") */ class Material { /** * @var integer $id * * @ORM\Column(name="id", type="integer") * @ORM\Id * @ORM\GeneratedValue(strategy="AUTO") */ private $id; /** * @var string $nombre * * @ORM\Column(name="nombre", type="string", length=100) */ private $nombre; /** * @ORM\Column(type="string", nullable="true") * * @Assert\Image(maxSize = "500k") */ protected $imagen; /** * @var datetime $created_at * * @ORM\Column(name="created_at", type="datetime") */ private $created_at; /** * @var datetime $updated_at * * @ORM\Column(name="updated_at", type="datetime") */ private $updated_at; /** * @ORM\ManyToMany(targetEntity="Tarea", mappedBy="materiales") */ protected $tareas; public function __construct() { $this->created_at = new \DateTime(); $this->updated_at = new \DateTime(); } public function __toString() { return $this->getNombre(); } /** * Sube la foto de la incidencia copiándola en el directorio que se indica y * guardando en la entidad la ruta hasta la foto * * @param string $directorioDestino Ruta completa del directorio al que se sube la foto */ public function subirImagen($directorioDestino) { if (null === $this->imagen) { return; } $nombreArchivoImagen = uniqid('material-').'-1.'.$this->imagen->guessExtension(); $this->imagen->move($directorioDestino, $nombreArchivoImagen); $this->setImagen($nombreArchivoImagen); } </code></pre> <p>This is my Tarea entity:</p> <pre><code>/** * Gitek\HotelBundle\Entity\Tarea * * @ORM\Table() * @ORM\Entity(repositoryClass="Gitek\HotelBundle\Entity\TareaRepository") */ class Tarea { /** * @var integer $id * * @ORM\Column(name="id", type="integer") * @ORM\Id * @ORM\GeneratedValue(strategy="AUTO") */ private $id; /** * @var string $nombre * * @ORM\Column(name="nombre", type="string", length=100) */ private $nombre; /** * @var datetime $created_at * * @ORM\Column(name="created_at", type="datetime") */ private $created_at; /** * @var datetime $updated_at * * @ORM\Column(name="updated_at", type="datetime") */ private $updated_at; /** @ORM\ManyToOne(targetEntity="Gitek\HotelBundle\Entity\Tipotarea") */ protected $tipotarea; /** * @ORM\ManyToMany(targetEntity="Material", inversedBy="tareas") * @ORM\JoinTable(name="material_tarea", * joinColumns={@ORM\JoinColumn(name="tarea_id", referencedColumnName="id")}, * inverseJoinColumns={@ORM\JoinColumn(name="material_id", referencedColumnName="id")} * ) */ protected $materiales; </code></pre> <p>And this my MaterialType form type:</p> <pre><code><?php namespace Gitek\BackendBundle\Form; use Symfony\Component\Form\AbstractType; use Symfony\Component\Form\FormBuilder; class MaterialType extends AbstractType { public function buildForm(FormBuilder $builder, array $options) { $builder ->add('nombre') ->add('imagen') ; } public function getName() { return 'gitek_hotelbundle_materialtype'; } } </code></pre> <p>As I said, when I upload de form I get "The file could not be found" error. It´s seems like the validation fails.</p> <p>Any help or clue?</p> <p>UPDATE: If in my TareaController I comment the validation line it works correctly. Any clue?</p>
