Question

我正在尝试使用VichUploaderBundle上传我的图片但是当我尝试创建新产品时出现以下错误

找不到字段“imageName”的映射

我按照https://github.com/dustin10/VichUploaderBundle/blob/master/Resources/doc/usage.md

            $em = $this->getDoctrine()->getManager();
            $em->persist($product);
            $em->flush($product);

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

我无法弄清问题是什么。

Answer 1

我只是在表单构建器中更改：

$builder->add('**imageName**', VichFileType::class, array(
          'required' => false,
          'allow_delete' => true, // not mandatory, default is true
          'download_uri' => true, // not mandatory, default is true
      ));

到

$builder->add('**imageFile**', VichFileType::class, array(
          'required' => false,
          'allow_delete' => true, // not mandatory, default is true
          'download_uri' => true, // not mandatory, default is true
      ));

它的工作，非常奇怪....;）

我认为问题来自于将您的产品实体与您的文件实体混合在一起。它们应该不同（这就是我自己使用Vich的方式）。

您应该拥有ProductImage实体：

namespace Car\MaintenanceBundle\Entity;
use Symfony\Component\HttpFoundation\File\File;
use Vich\UploaderBundle\Mapping\Annotation as Vich;
use Doctrine\ORM\Mapping as ORM;

/**
 * Product
 *
 * @ORM\Table(name="product_image")
 * 
 * @ORM\Entity()
 * @Vich\Uploadable
 */
class ProductImage
{
/**
 * @var int
 *
 * @ORM\Column(name="id", type="integer")
 * @ORM\Id
 * @ORM\GeneratedValue(strategy="AUTO")
 */
private $id;

/**
* NOTE: This is not a mapped field of entity metadata, just a simple property.
*
* @Vich\UploadableField(mapping="product_image", fileNameProperty="imageName")
*
* @var File
*/
private $imageFile;

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

/**
 * @var \DateTime
 *
 * @ORM\Column(name="update_at", type="datetime")
 */
private $updateAt;

/**
 * Get id
 *
 * @return int
 */
public function getId()
{
    return $this->id;
// ...

然后在您的产品实体中添加一个属性$ image

/**
 * @ORM\OneToOne(targetEntity="Car\MaintenanceBundle\Entity\ProductImage", cascade={"persist"})
 * @ORM\JoinColumn(name= "image", referencedColumnName="id", nullable=true, onDelete="SET NULL")
 */
private $image;

最后，在你的ProductType班级

$builder
  ->add('productName', TextType::class)
  ->add('brochure', TextType::class)
  ->add('image', ProductImageType::class, array(
    'required'      => false,
  ))
;

使用ProductImageType：

// ...
use Symfony\Component\Form\Extension\Core\Type\FileType;

class ProductImageType extends AbstractType
{
    /**
     * @param FormBuilderInterface $builder
     * @param array $options
     */
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder
            ->add('imageFile', FileType::class, array(
                'label' => false
            ));
    }

    /**
     * @param OptionsResolverInterface $resolver
     */
    public function configureOptions(OptionsResolver $resolver)
    {
        $resolver->setDefaults(array(
            'data_class' => 'CarMaintenanceBundle\Entity\ProductImage'
        ));
    }
