Symfony 6中的VichUploaderBundle

Question

我希望你能帮我，因为我在寻找，我迷路了。

我正在尝试上传图片在我的symfony 6项目与VichUploaderBundle。

我用的是医生：https://github.com/dustin10/VichUploaderBundle/blob/master/docs/usage.md#step-1-configure-an-upload-mapping

但我有个错误：

类"App\Entity\Client“不可上载。如果您使用注释来配置VichUploaderBundle，您可能只是忘记在实体的顶部添加@Vich\Uploadable。如果不使用注释，请检查配置文件是否位于正确的位置。在这两种情况下，清除缓存也可以解决问题。

我的vich_uploader.yaml：

vich_uploader:
    db_driver: orm


    mappings:
       clients_logo:
           uri_prefix: '%client_logo%'
           upload_destination: '%kernel.project_dir%/public%client_logo%'
           namer: Vich\UploaderBundle\Naming\SmartUniqueNamer

我的客户实体：

<?php

namespace App\Entity;

use Doctrine\ORM\Mapping as ORM;
use App\Repository\ClientRepository;
use Doctrine\Common\Collections\Collection;
use Symfony\Component\HttpFoundation\File\File;
use Doctrine\Common\Collections\ArrayCollection;
use Vich\UploaderBundle\Mapping\Annotation as Vich;

#[ORM\Entity(repositoryClass: ClientRepository::class)]
#[Vich\Uploadable]
class Client
{
    #[ORM\Id]
    #[ORM\GeneratedValue]
    #[ORM\Column(type: 'integer')]
    private $id;

    #[ORM\Column(type: 'integer')]
    private $numero_client;

    /**
    * Some fields
    */

    /**
     * NOTE: This is not a mapped field of entity metadata, just a simple property.
     */
    #[Vich\UploadableField(mapping: 'clients_logo', fileNameProperty: 'logo')]
    private ?File $imageFile = null;

    #[ORM\Column(type: 'string', length: 255, nullable: true)]
    private $logo;


    #[ORM\Column(type: 'datetime', nullable: true)]
    private ?\DateTimeInterface $updatedAt = null;

    public function __construct()
    {
        $this->applis = new ArrayCollection();
    }

    public function getId(): ?int
    {
        return $this->id;
    }

    public function getLogo(): ?string
    {
        return $this->logo;
    }

    public function setLogo(?string $logo): self
    {
        $this->logo = $logo;

        return $this;
    }

    /**
     * If manually uploading a file (i.e. not using Symfony Form) ensure an instance
     * of 'UploadedFile' is injected into this setter to trigger the update. If this
     * bundle's configuration parameter 'inject_on_load' is set to 'true' this setter
     * must be able to accept an instance of 'File' as the bundle will inject one here
     * during Doctrine hydration.
     *
     * @param File|\Symfony\Component\HttpFoundation\File\UploadedFile|null $imageFile
     */
    public function setImageFile(?File $imageFile = null): void
    {
        $this->imageFile = $imageFile;

        if (null !== $imageFile) {
            // It is required that at least one field changes if you are using doctrine
            // otherwise the event listeners won't be called and the file is lost
            $this->updatedAt = new \DateTimeImmutable();
        }
    }

    public function getImageFile(): ?File
    {
        return $this->imageFile;
    }

    public function getBddClient(): ?BaseClient
    {
        return $this->bdd_client;
    }

    public function setBddClient(?BaseClient $bdd_client): self
    {
        $this->bdd_client = $bdd_client;

        return $this;
    }

    /**
     * @return Collection<int, Applis>
     */
    public function getApplis(): Collection
    {
        return $this->applis;
    }

    public function addAppli(Applis $appli): self
    {
        if (!$this->applis->contains($appli)) {
            $this->applis[] = $appli;
        }

        return $this;
    }

    public function removeAppli(Applis $appli): self
    {
        $this->applis->removeElement($appli);

        return $this;
    }

    public function getUpdateAt(): ?\DateTimeInterface
    {
        return $this->updatedAt;
    }

    public function setUpdateAt(): self
    {
        $this->updatedAt = new \DateTimeImmutable();

        return $this;
    }
}

我的FormType：

<?php

namespace App\Form;

use App\Entity\Client;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\CallbackTransformer;
use Symfony\Component\Form\FormBuilderInterface;
use Vich\UploaderBundle\Form\Type\VichImageType;
use Symfony\Component\Validator\Constraints\File;
use Symfony\Component\OptionsResolver\OptionsResolver;
use Symfony\Component\Form\Extension\Core\Type\DateType;
use Symfony\Component\Form\Extension\Core\Type\FileType;
use Symfony\Component\Form\Extension\Core\Type\TextType;
use Symfony\Component\Form\Extension\Core\Type\EmailType;
use Symfony\Component\Form\Extension\Core\Type\ChoiceType;

class ClientType extends AbstractType
{
    public function buildForm(FormBuilderInterface $builder, array $options): void
    {
        $builder
            ->add('nom', TextType::class, [
                'label' => false,
            ])
            //Some add fields
            ->add('imageFile', VichImageType::class, [
                'required' => false
            ]);

        //Indispensable pour faire fonctionner le select du formulaire sinon erreur 500
        $builder->get('type_contrat')
            ->addModelTransformer(new CallbackTransformer(
                function ($typeContratArray) {
                    // transform the array to a string
                    return count($typeContratArray) ? $typeContratArray[0] : null;
                },
                function ($typeContratString) {
                    // transform the string back to an array
                    return [$typeContratString];
                }
            ));
    }

    public function configureOptions(OptionsResolver $resolver): void
    {
        $resolver->setDefaults([
            'data_class' => Client::class,
        ]);
    }
}

在我的形式中：

<div class="col-md-6">
    {{ form_row(form.imageFile, { 
        label: 'Logo',
        'attr': {'class': 'form-control'}
    }) }}
</div>

谁能解释这是怎么回事？

假设您使用的是Php 8+，那么将包配置为使用属性而不是注释

vich_uploader:
    metadata:
        type: attribute

参考文献文档

编辑21 11月21日2022:作为包的v2，attribute是默认值。
