Customizing the Installation Process¶

To customize the installation process and modify the database structure and/or data that are loaded in the OroCommerce after installation, you can:

Execute Custom Migrations
Load Custom Data Fixtures

Execute Custom Migrations¶

You can create your own migrations that can be executed during the installation. A migration is a class which implements the Migration interface:

// src/Acme/DemoBundle/Migration/CustomMigration.php
namespace Acme\DemoBundle\Migration;

use Doctrine\DBAL\Schema\Schema;
use Oro\Bundle\MigrationBundle\Migration\Migration;
use Oro\Bundle\MigrationBundle\Migration\QueryBag;

class CustomMigration implements Migration
{
    public function up(Schema $schema, QueryBag $queries)
    {
        // ...
    }
}

In the up(), you can modify the database schema and/or add additional SQL queries that are executed before and after the schema changes.

The MigrationsLoader dispatches two events when migrations are being executed, oro_migration.pre_up and oro_migration.post_up. You can listen to either event and register your own migrations in your event listener. Use the addMigration() method of the passed event instance to register your custom migrations:

// src/Acme/DemoBundle/EventListener/RegisterCustomMigrationListener.php
namespace Acme\DemoBundle\EventListener;

use Acme\DemoBundle\Migration\CustomMigration;
use Oro\Bundle\MigrationBundle\Event\PostMigrationEvent;
use Oro\Bundle\MigrationBundle\Event\PreMigrationEvent;

class RegisterCustomMigrationListener
{
    // listening to the oro_migration.pre_up event
    public function preUp(PreMigrationEvent $event)
    {
        $event->addMigration(new CustomMigration());
    }

    // listening to the oro_migration.post_up event
    public function postUp(PostMigrationEvent $event)
    {
        $event->addMigration(new CustomMigration());
    }
}

Tip

You can learn more about custom event listeners in the Symfony documentation.

Migrations registered in the oro_migration.pre_up event are executed before the main migrations while migrations registered in the oro_migration.post_up event are executed after the main migrations have been processed.

Load Custom Data Fixtures¶

To load your own data fixtures, you will need to implement Doctrine’s “FixtureInterface”:

// src/Acme/DemoBundle/Migrations/Data/ORM/CustomFixture.php
namespace Acme\DemoBundle\Migrations\Data\ORM;

use Doctrine\Common\DataFixtures\FixtureInterface;
use Doctrine\Common\Persistence\ObjectManager;

class CustomFixture implements FixtureInterface
{
    public function load(ObjectManager $manager)
    {
        // ...
    }
}

Caution

Your data fixture classes must reside in the “Migrations/Data/ORM” sub-directory of your bundle to be loaded automatically during the installation.

Tip

Read the doctrine data fixtures documentation to learn more about the Doctrine Data Fixtures extension.
