我有一个实体 "支持"，我想链接一个文件（PDF，DOC，...）。我已经按照文档和一些视频的帮助，但我总是有这个错误。
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。

这里是我的 "newAction"，用于从控制器中创建一个新的 "Support"：`。
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]);
}`
这里是我的 "SupportType "来生成表单： `。
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.这里是我的实体 "Support".这里是我的 "newAction".创建一个新的 "Support "从控制器:`这里是我的 "SupportType".生成Form:`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">

</div>
{% endif %}
{% for message in app.flashes('success') %}
<div class=" alert alert-success" style="font-size: 1.7rem;">

</div>
{% endfor %}</p>

</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>
尽管我使用的视频和论坛，我没有找到任何解决方案。我需要你的帮助thanks :-)
输入的 "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')
;
}
...
}
