8. Sortable behavior in admin listing

This is a full working example of how to implement a sortable feature in your Sonata admin listing

8.1. Background

A sortable behavior is already available for one-to-many relationships (https://docs.sonata-project.org/projects/SonataDoctrineORMAdminBundle/en/4.x/reference/form_field_definition/#advanced-usage-one-to-many). However there is no packaged solution to have some up and down arrows to sort your records such as showed in the following screen

8.2. Pre-requisites

8.2.1. Configuration

you already have SonataAdmin and DoctrineORM up and running
you already have an Entity class for which you want to implement a sortable feature. For the purpose of the example we are going to call it Client.
you already have an Admin set up, in this example we will call it ClientAdmin

8.2.2. Bundles

install gedmo/doctrine-extensions bundle in your project (check stof/doctrine-extensions-bundle for easier integration in your project) and enable the sortable feature in your config
install runroom-packages/sortable-behavior-bundle at least version ^0.16 and enable it in config/bundles.php

8.3. The recipe

First of all we are going to add a position field in our Client entity:

#[Gedmo\SortablePosition]
#[ORM\Column(type: Types::INTEGER)]
private ?int $position = null;

Then we need to inject the Sortable listener. If you only have the Gedmo bundle enabled, you only have to add the listener to your services.yaml file and skip this step.

# config/services.yaml

services:
    gedmo.listener.sortable:
        class: Gedmo\Sortable\SortableListener
        calls:
            - [setAnnotationReader, ['@annotation_reader']]
        tags:
            - { name: doctrine.event_subscriber, connection: default }

If you have the stof/doctrine-extensions-bundle, you only need to enable the sortable feature in your configuration such as

# config/packages/stof_doctrine_extensions.yaml

stof_doctrine_extensions:
    orm:
        default:
            sortable: true

In our ClientAdmin we are going to add a custom action in the configureListFields method and use the default twig template provided in the RunroomSortableBehaviorBundle:

$list
    ->add(ListMapper::NAME_ACTIONS, ListMapper::TYPE_ACTIONS, [
        'actions' => [
            'move' => [
                'template' => '@RunroomSortableBehavior/sort.html.twig'
            ],
        ]
    ]);

In order to add new routes for these actions and to apply right sorting use Runroom\SortableBehaviorBundle\Admin\SortableAdminTrait

// src/Admin/ClientAdmin.php

namespace App\Admin;

use Runroom\SortableBehaviorBundle\Admin\SortableAdminTrait;
use Sonata\AdminBundle\Admin\AbstractAdmin;

final class ClientAdmin extends AbstractAdmin
{
    use SortableAdminTrait;
}

Define Admin in services.yaml

# config/services.yaml

services:
    app.admin.client:
        class: App\Admin\ClientAdmin
        tags:
            - { name: sonata.admin, model_class: App\Entity\Client, manager_type: orm, label: 'Clients' }

Now we need to define sortable action:

// src/Admin/ClientAdmin.php

namespace App\Admin;

use Runroom\SortableBehaviorBundle\Admin\SortableAdminTrait;
use Sonata\AdminBundle\Admin\AbstractAdmin;
use Sonata\AdminBundle\Datagrid\ListMapper;

final class ClientAdmin extends AbstractAdmin
{
    use SortableAdminTrait;

    protected function configureListFields(ListMapper $list): void
    {
        $list
            ->addIdentifier('name')
            ->add('enabled')
            ->add(ListMapper::NAME_ACTIONS, ListMapper::TYPE_ACTIONS, [
                'actions' => [
                    'move' => [
                        'template' => '@RunroomSortableBehavior/sort.html.twig'
                    ],
                ],
            ])
        ;
    }
}
