Error service symfony : A namer must be configured - symfony

Question

I want to use create folder function with vich considering id.
My service:
<?php
namespace App\Service\Namers;
use Vich\UploaderBundle\Mapping\PropertyMapping;
use Vich\UploaderBundle\Naming\DirectoryNamerInterface;
use App\Entity\Users;
class VichNamer implements DirectoryNamerInterface {
public function directoryName(object $object, PropertyMapping $mapping): string {
return 'test';
}
}
my vich_uploader.yaml:
vich_uploader:
db_driver: orm
metadata:
type: attribute
mappings:
tattoo_images:
uri_prefix: /images/
upload_destination: '%kernel.project_dir%/public/images/'
directory_namer: App\Service\Namers\VichNamer
My services.yaml:
parameters:
images_directory: '%kernel.project_dir%/public/uploads'
services:
# default configuration for services in *this* file
_defaults:
autowire: true # Automatically injects dependencies in your services.
autoconfigure: true # Automatically registers your services as commands, event subscribers, etc.
# makes classes in src/ available to be used as services
# this creates a service per class whose id is the fully-qualified class name
App\:
resource: '../src/'
exclude:
- '../src/DependencyInjection/'
- '../src/Entity/'
- '../src/Kernel.php'
# add more service definitions when explicit configuration is needed
# please note that last definitions always *replace* previous ones
App\EventSubscriber\EasyAdminSubscriber:
tags:
- { name: 'doctrine.event_subscriber', event: preUpdate }
App\Service\Namers\VichNamer:
public: true
tags:
- { name: 'vich.namedirectory' }
My error:
A namer must be configured.

The namer is used to name the files and directories it saves to the filesystem
You can add nammer by default like this in your config:
vich_uploader:
.....
mappings:
tattoo_images:
uri_prefix: /images/
upload_destination: '%kernel.project_dir%/public/images/'
directory_namer: App\Service\Namers\VichNamer
namer:
service: Vich\UploaderBundle\Naming\PropertyNamer
options: { property: 'slug' }
You can see all options working with namer here : namers
