Я создаю сайт, который показывает проект, который я сделал. Поэтому, когда я добавляю новый проект, я не хочу сам изменять свою базу данных. Поэтому с пакетом easyAdmin я создаю форму администратора для управления ими. Для загрузки файла я использую пакет vichuploader. До сих пор проблем не было, но когда я хочу удалить этот проект или изменить файл, я получил эту ошибку 'Ожидаемый аргумент типа "строка", "NULL", заданный в пути свойства "name".'
Я даже не знаю, откуда возникла ошибка.
Мой объект Project, содержащий файл:
/**
* @ORM\Entity(repositoryClass="App\Repository\ProjectRepository")
* @ApiResource
* @Vich\Uploadable
*/
class Project
{
/**
* @ORM\Id()
* @ORM\GeneratedValue()
* @ORM\Column(type="integer")
*/
private $id;
/**
* @ORM\Column(type="string", length=255)
*/
private $name;
/**
* @Vich\UploadableField(mapping="projects", fileNameProperty="name")
* @var File
*/
private $projectFile;
/**
* @ORM\Column(type="string", length=255)
*/
private $url;
/**
* @ORM\Column(type="datetime")
*/
private $updateAt;

$this->url = '%app.path.projects%' . $this->name;
}
}

{
return $this->updateAt;
}
public function setUpdateAt(\DateTimeInterface $updateAt): self

$this->updateAt = $updateAt;
return $this;
}
}
Мой файл easy_admin.yaml:
easy_admin:
entities:
# List the entity class name you want to manage
Project:
class: App\Entity\Project
form:
fields:
- { property: 'name' }
- { property: 'projectFile', type: 'file' }
Файл My services.yaml:
parameters:
locale: 'fr'
app.path.projects: /projects
Мой файл vich_uploader.yaml:
vich_uploader:
db_driver: orm
mappings:
projects:
uri_prefix: '%app.path.projects%'
upload_destination: '%kernel.project_dir%/public%app.path.projects%'
Вот ошибка, которую я получил:
