i simply try to update/delete a file in sonata admin with VichUploader bundle.
But in both cases i have this error : Expected argument of type "string", "null" given at property path "filename".
note :
- on delete, the entity is delete anyway and the file is correctly moved to trash after this error, but update is impossible, there is just this error
- on update, the media->setFile() is called and the media->updatedAt is modified before triggering the error
Here is my entity :
<?php
namespace My\CoreBundle\Entity;
use Doctrine\DBAL\Types\Types;
use My\CoreBundle\Repository\MediaRepository;
use Doctrine\ORM\Mapping as ORM;
use Knp\DoctrineBehaviors\Contract\Entity\TimestampableInterface;
use Knp\DoctrineBehaviors\Model\Timestampable\TimestampableTrait;
use Vich\UploaderBundle\Mapping\Annotation as Vich;
use Symfony\Component\HttpFoundation\File\File;
#[ORM\Table(name: 'my_media')]
#[Vich\Uploadable]
#[ORM\Entity(repositoryClass: MediaRepository::class)]
class Media implements TimestampableInterface
{
use TimestampableTrait;
#[Vich\UploadableField(mapping: 'media', fileNameProperty: 'filename')]
private ?File $file = null;
#[ORM\Id]
#[ORM\GeneratedValue]
#[ORM\Column]
private ?int $id = null;
#[ORM\Column(length: 255, unique: true)]
private ?string $name = null;
#[ORM\Column(type: Types::TEXT)]
private ?string $caption = null;
#[ORM\Column(length: 255, unique: true)]
private ?string $filename = null;
// ##################### Custom methods #####################
public function __toString()
{
return $this->name;
}
public function getUrl(): ?string
{
return sprintf('/uploads/images/%s', $this->filename);
}
public function setFile(?File $file = null): void
{
$this->file = $file;
if (null !== $file) {
// 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 getFile(): ?File
{
return $this->file;
}
// ##################### generated methods #####################
public function getId(): ?int
{
return $this->id;
}
public function getName(): ?string
{
return $this->name;
}
public function setName(string $name): self
{
$this->name = $name;
return $this;
}
public function getCaption(): ?string
{
return $this->caption;
}
public function setCaption(string $caption): self
{
$this->caption = $caption;
return $this;
}
public function getFilename(): ?string
{
return $this->filename;
}
public function setFilename(string $filename): self
{
$this->filename = $filename;
return $this;
}
}
The admin controller :
// [...]
final class MediaAdmin extends AbstractAdmin
{
protected function configureFormFields(FormMapper $formMapper): void
{
$formMapper
->add('name')
->add('caption')
->add('file', VichImageType::class, ['required' => false])
->end();
}
// [...]
}
Vich config :
vich_uploader:
db_driver: orm
storage: flysystem
mappings:
media:
uri_prefix: /uploads/images
upload_destination: default.storage
namer: Vich\UploaderBundle\Naming\SmartUniqueNamer
SOLUTION
the entity's "filename" property NEEDS to be nullable if using vichuploader.
WARNING : don't forget to edit the setter allowing nullable parameter with ?
correct entity :
<?php
namespace My\CoreBundle\Entity;
// […]
#[ORM\Table(name: 'my_media')]
#[Vich\Uploadable]
#[ORM\Entity(repositoryClass: MediaRepository::class)]
class Media implements TimestampableInterface
{
use TimestampableTrait;
#[Vich\UploadableField(mapping: 'media', fileNameProperty: 'filename')]
private ?File $file = null;
//[…]
#[ORM\Column(length: 255, nullable: true)]
private ?string $filename = null;
//[…]
public function setFilename(?string $filename): self // <<<<<< IMPORTANT : DONT FORGET '?' or doctrine will trigger not nullable error !
{
$this->filename = $filename;
return $this;
}
}
