vich 上传图片在删除时不能为空

Question

我有一个问题，我在我的网站上使用了 EasyAdminBundle 和 VichUploaderBundle。问题是当我删除图像时 returns 出现错误，如下所示：

Integrity constraint violation: 1048 Le champ 'image' ne peut être vide (null)

这是我的代码：

config.yml :

vich_uploader:
db_driver: orm
mappings:
        photo_images:
            uri_prefix:         %app.path.photo_images%
            upload_destination: %kernel.root_dir%/../web/uploads/images
            namer:              vich_uploader.namer_uniqid

我的 easyadmin 配置：

entities:
    Event:
        class: AppBundle\Entity\Event
        label: 'Evenements'
        new:
            title: 'Création événement'
            fields: 
                - { property: 'nom', label: 'Nom/Intitulé' }
                - { property: 'date', label: 'Date' }
                - { property: 'heure', label: 'Heure' }
                - { property: 'lieu', label: 'Lieu' }
                - { property: 'categorie', label: 'Catégorie' }
                - { property: 'prix', label: 'Prix' }
                - { property: 'imageFile', label: 'Image',type: 'vich_image' }
                - { property: 'isActive', label: 'Publié' }
        edit:
            title: 'Evenement (#%%entity_id%%)'
            fields: 
                - { property: 'nom', label: 'Nom/Intitulé' }
                - { property: 'date', label: 'Date' }
                - { property: 'heure', label: 'Heure' }
                - { property: 'lieu', label: 'Lieu' }
                - { property: 'categorie', label: 'Catégorie' }
                - { property: 'prix', label: 'Prix' }
                - { property: 'imageFile', label: 'Image', type: 'vich_image' }
                - { property: 'isActive', label: 'Publié' }

还有我的实体：

我不明白错误可能来自哪里，或者我做错了什么。我遵循了本网站上的教程：Link

在您的实体事件中添加 nullable=true in:

/**
 * @ORM\Column(type="string", length=255, nullable=true)
 * @var string
 */
private $image;
