我正在使用带有 symfony4 的 easy-admin 的 vich-uploader 捆绑包。设置后，我在尝试删除或更新实体时收到此错误
属性路径“imageName”中给出的“字符串”类型的预期参数，“NULL”。
对于这种常见情况，应用程序的配置是最容易的。矿山测试实体：
<?php
namespace App\Entity;
use Doctrine\ORM\Mapping as ORM;
use Symfony\Component\HttpFoundation\File\File;
use Vich\UploaderBundle\Mapping\Annotation as Vich;
/**
* @ORM\Entity(repositoryClass="App\Repository\TestRepository")
* @Vich\Uploadable
*/
class Test
{
/**
* @ORM\Id()
* @ORM\GeneratedValue()
* @ORM\Column(type="integer")
*/
private $id;
/**
* @ORM\Column(type="string", length=255)
*/
private $imageName;
/**
* @Vich\UploadableField(mapping="test_images", fileNameProperty="imageName")
* @var File
*/
private $imageFile;
/**
* @ORM\Column(type="datetime")
* @var \DateTime
*/
private $updatedAt;
public function getId()
{
return $this->id;
}
public function getImageName()
{
return $this->imageName;
}
public function setImageName(string $image)
{
$this->imageName = $image;
return $this;
}
public function setImageFile(File $image = null)
{
$this->imageFile = $image;
if ($image) {
$this->updatedAt = new \DateTime('now');
}
}
public function getImageFile()
{
return $this->imageFile;
}
public function getUpdatedAt()
{
return $this->updatedAt;
}
public function setUpdatedAt(\DateTime $datetime)
{
$this->updatedAt = $datetime;
return $this;
}
}
我的简单管理 yaml 配置
easy_admin:
entities:
Test:
class: App\Entity\Test
form:
fields:
- { property: 'imageFile', type: 'vich_image' }
# ...
list:
fields:
- { property: 'image', type: 'image', base_path: '%app.path.banner_images%' }
# ...
show:
fields:
- { property: 'image', type: 'image', base_path: '%app.path.banner_images%' }
