Create Custom Entities

A custom entity is an entity that has no PHP class in any bundle. The definition of such an entity is created automatically in the Symfony cache. To create a custom entity, you can use ExtendExtension, as illustrated below:

<?php

namespace Acme\Bundle\TestBundle\Migrations\Schema\v1_0;

use Doctrine\DBAL\Schema\Schema;
use Oro\Bundle\EntityExtendBundle\Migration\Extension\ExtendExtension;
use Oro\Bundle\EntityExtendBundle\Migration\Extension\ExtendExtensionAwareInterface;
use Oro\Bundle\EntityExtendBundle\EntityConfig\ExtendScope;
use Oro\Bundle\MigrationBundle\Migration\Migration;
use Oro\Bundle\MigrationBundle\Migration\QueryBag;

class AcmeTestBundle implements Migration, ExtendExtensionAwareInterface
{
    protected $extendExtension;

    public function setExtendExtension(ExtendExtension $extendExtension)
    {
        $this->extendExtension = $extendExtension;
    }

    public function up(Schema $schema, QueryBag $queries)
    {
        $table = $this->extendExtension->createCustomEntityTable(
            $schema,
            'TestCustomEntity'
        );
        $table->addColumn(
            'name',
            'string',
            [
                'length' => 100,
                'oro_options' => [
                    'extend'  => ['owner' => ExtendScope::OWNER_CUSTOM],
                ]
            ]
        );
        $this->extendExtension->addManyToOneRelation(
            $schema,
            $table,
            'users',
            'oro_user',
            'first_name'
        );
    }
}

Adding fields and relationships to custom entities is the same as for extended entities. For details, see Add Entity Fields and Add Entity Relationships.
