Symfony/ VichUploaderBundle: DirectoryNamer

Question

我正在尝试实现一个DirectoryNamer，但不幸的是，这会导致一个错误消息，我不知道下一步该做什么。

财务主任(节选)：

if ($form->isSubmitted() && $form->isValid()) {

        $em = $this->getDoctrine()->getManager();
        $em->persist($image);
        $em->flush();
        //...
}

DirectoryNamer服务类：

use Vich\UploaderBundle\Naming\DirectoryNamerInterface;

class ArtistDirectoryNamer implements DirectoryNamerInterface
{
    public function directoryName($image, PropertyMapping $mapping) {   
        return $image->getArtist()->getId();
    }
}

VichUploader配置：

vich_uploader:
db_driver: orm
mappings:
    upload_artists:
        uri_prefix:         /upload/artists
        upload_destination: %kernel.root_dir%/../web/upload/artists
        directory_namer:    macms_admin.artist_directory_namer
        namer:              vich_uploader.namer_uniqid
        inject_on_load:     false
        delete_on_update:   true
        delete_on_remove:   true

..。以及重发错误消息：

编译错误: ArtistDirectoryNamer::directoryName()声明必须与Vich\UploaderBundle\Naming\DirectoryNamerInterface::directoryName($object，Vich\UploaderBundle\ must \PropertyMapping$mapping兼容

我的密码怎么了？在我实现DirectoryNamer之前，上传工作正常，文件存储在'/ upload /artists‘中。

有什么暗示吗？提前感谢！

Answer 1

也许您忘记了use类的Vich\UploaderBundle\Mapping\PropertyMapping语句？

Answer 2

由于K-Phoen -这是工作解决方案：

namespace Acme\Project\AdminBundle\Services;

use Vich\UploaderBundle\Naming\DirectoryNamerInterface;
use Vich\UploaderBundle\Mapping\PropertyMapping;

class ArtistDirectoryNamer implements DirectoryNamerInterface
{
    public function directoryName($image, PropertyMapping $mapping) {   
        return $image->getArtist()->getId();
    }
}
