Easyadmin 中的照片字段未显示

Question

我正在尝试在我的包中显示一些图像（使用 easyadmin 包）和 symfony 3.4 但是，由于某种原因，这些照片没有显示。这是我的代码：在 config.yml 中：

       Employee:
        class: BackofficeBundle\Entity\Employee
        role_prefix: ROLE_EMPLOYEE_MANAGER
        list:
            fields:
                - id
                - Name
                - { property: 'photo', label: 'EMPLOYEE AVATAR', type: 'image' , base_path: '/images/' }

在我的员工实体中：

 /**
 * @ORM\Column(name="photo", type="string", length=500)
 * @Assert\File(maxSize="500k", mimeTypes={"image/jpeg", "image/jpg", "image/png", "image/GIF"})
 */
private $photo;

在我的 EmployeeType.php

 $builder->add('photo', FileType::class, array('data_class'=>null, 'required'=>false
    ));

照片未显示在“列表”页面中，当我单击编辑时出现此错误：

The form's view data is expected to be an instance of class Symfony\Component\HttpFoundation\File\File, but is a(n) string. You can avoid this error by setting the "data_class" option to null or by adding a view transformer that transforms a(n) string to an instance of Symfony\Component\HttpFoundation\File\File.

对于这种情况，请考虑使用VichUploadBundle https://symfony.com/doc/master/bundles/EasyAdminBundle/integration/vichuploaderbundle.html
