Symfony 4 - VichUploaderBundle - 文件名未保存在数据库中

Question

我有一个实体“支持”关于我想链接文件（PDF、DOC、...）的女巫。我已经按照文档和一些视频来提供帮助，但我总是遇到这个错误：

SQLSTATE[23000]: Integrity constraint violation: 1048 The field 'filename' can't be empty (null)

而且我的数据库中没有任何持久性。 这是我的实体“支持”：`

            {
                return $this->supportFile;

            {
                $this->supportFile = $supportFile;
                if (null !== $supportFile) {
                    // 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();
                }
                return $this; 
            }  

            public function setFileSize(?int $fileSize): void
            {
                $this->fileSize = $fileSize ;
            }

            public function getFileSize(): ?int
            {
                return $this->fileSize;
            }

        }

在这里我的“newAction”从控制器创建一个新的“支持”：`

public function new(Request $request, $type, $salle, $matiere): Response
{
    $user = $this->getUser();
    if ($user->getRoles()==array('ROLE_PROF')) {
        $support = new Support();
        $type_de_support = $this->typedeSupportRepository->findOneBy(['intitule'=>$type]);
        $salle_de_support = $this->salleRepository->findOneBy(['nom'=>$salle]);
        $matiere_de_support = $this->matiereRepository->findOneBy(['intitule'=>$matiere]);
        $support->setTypedeSupport($type_de_support)
                ->addSalle($salle_de_support)
                ->setMatiere($matiere_de_support);
        $form = $this->createForm(SupportType::class, $support);
        $form->handleRequest($request);

        if ($form->isSubmitted() && $form->isValid()) {
            dump($support);
            $entityManager = $this->getDoctrine()->getManager();
            $entityManager->persist($support);
            $entityManager->flush();

            return $this->redirectToRoute('support_index',["type"=>$type,"salle"=>$salle ,"matiere"=>$matiere]);
        }`

这是我生成表单的“SupportType”：`

        namespace App\Form;

        use App\Entity\Support;
        use Symfony\Component\Form\AbstractType;
        use Symfony\Component\Form\Extension\Core\Type\FileType;
        use Symfony\Component\Form\FormBuilderInterface;
        use Symfony\Component\OptionsResolver\OptionsResolver;

        class SupportType extends AbstractType
        {
            public function buildForm(FormBuilderInterface $builder, array $options)
            {
                $builder
                    ->add('titre')
                    ->add('supportFile', FileType::class)
                    ->add('desciption')
                ;
            }

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

然后是配置文件： vich_uploader: db_driver: orm mappings: support_file: uri_prefix: /supports/teste upload_destination: '%kernel.project_dir%/public/supports/teste' namer: vich_uploader.namer_uniqid

视图： <div class="col-md-4"> <div class="card text-white bg-primary mb-3"> <div class="card-header text-center" style="font-size: 2.3rem;">Modifier le support</div> <div class="card-body"> <p class="card-text">
{% if error is defined and error %} <div class=" alert alert-danger" style="font-size: 1.3rem;"> {{error}} </div> {% endif %} {% for message in app.flashes('success') %} <div class=" alert alert-success" style="font-size: 1.7rem;"> {{message}} </div> {% endfor %}</p> <form method="post" action="" accept-charset="UTF-8"> <input type="hidden" name="action" value="users/send-password-reset-email"> <div class="form-group"> {{form_row(form.titre)}} </div> <div class="form-group"> {{form_row(form.supportFile)}} </div> <div class="form-group"> {{form_row(form.desciption)}} </div> {{ form_rest(form) }} <input type="submit" value="{{ button_label|default('Save') }}" class="btn btn-success col-12"> </form> <br><br> </div> </div>
</div>

尽管我使用了视频和论坛，但我没有找到任何解决方案。我需要你的帮助 谢谢:-)

输入“supportFile”需要是 VichFileType::class 而不是 FileType::class

class SupportType extends AbstractType
{
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder
        ->add('titre')
        ->add('supportFile', VichFileType::class)
        ->add('desciption')
        ;
    }
...
}
