  #regions: PersistentCollection {#717 ▶}
  #genre: Genre {#739 ▶}
  #language: Language {#745 ▶}
} 

here is my Movie Entity class

<?php

namespace Application\NS\AdminBundle\Entity;

use Doctrine\ORM\Mapping as ORM;
use Vich\UploaderBundle\Mapping\Annotation as Vich;
use Symfony\Component\HttpFoundation\File\File;


/**
 * Movie
 *
 * @ORM\Table(name="movie")
 * @ORM\Entity(repositoryClass="Application\NS\AdminBundle\Repository\MovieRepository")
 * @Vich\Uploadable
 */
class Movie
{



    /**
     * @Vich\UploadableField(mapping="feature_image", fileNameProperty="featureImageName")
     * @var File
     */
    private $featureImageFile;

    /**
     * @ORM\Column(type="string", length=255, nullable=true)
     * @var string
     */
    private $featureImageName; 

    /**
     * Set featureImageName
     * @param string $featureImageName
     * @return object
     */
    public function setFeatureImageName($featureImageName) {
        $this->featureImageName = $featureImageName;
        return $this;
    }

    /**
     * Get featureImageName
     * @return string
     */
    public function getFeatureImageName(){
        return $this->featureImageName;
    }

}

here is my admin class

/**
 * @param FormMapper $formMapper
 */
protected function configureFormFields(FormMapper $formMapper)
{
    $formMapper
     ->add('featureImageFile', 'vich_image', array( 'required' => false, 'allow_delete'  => true, 'download_link' => false))
}                

what i am missing can any one help ? is there any alternative method to inject uploaded file information into Entity Object

Answer 1

we need to manually refresh the doctrine object to to load updated properties (vich uploader inject file information to object property via events)

 $this->getContainer()->get('doctrine.orm.entity_manager')->refresh($movie);
