php - Symfony 6 中的 VichUploaderBundle

Question

我希望你能帮助我，因为我正在寻找，我迷路了:(

我正在尝试使用 VichUploaderBundle 在我的 symfony 6 项目中上传图片。

我使用了文档:https://github.com/dustin10/VichUploaderBundle/blob/master/docs/usage.md#step-1-configure-an-upload-mapping

但我有这个错误:

The class "App\Entity\Client" is not uploadable. If you use annotations to configure VichUploaderBundle, you probably just forgot to add @Vich\Uploadable on top of your entity. If you don't use annotations, check that the configuration files are in the right place. In both cases, clearing the cache can also solve the issue.

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:

我的表单类型:

<?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\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,
        ]);
    }
}

在我的表单中:

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

任何人都可以解释发生了什么？ :(

假设您使用的是 Php 8+，请将包配置为使用 attributes 而不是 annotations

vich_uploader:
    metadata:
        type: attribute
