Doctrine and composite unique keys

Question

I want to do composite unique key in doctrine. Those are my fields:

/**
 * @var string $videoDimension
 *
 * @Column(name="video_dimension", type="string", nullable=false)
 */
private $videoDimension;

/**
 * @var string $videoBitrate
 *
 * @Column(name="video_bitrate", type="string", nullable=false)
 */
private $videoBitrate;

How can I show doctrine, that those combined together are composite unique key?

Answer 1

Answer the question:

use Doctrine\ORM\Mapping\UniqueConstraint;

/**
 * Common\Model\Entity\VideoSettings
 *
 * @Table(name="video_settings", 
 *    uniqueConstraints={
 *        @UniqueConstraint(name="video_unique", 
 *            columns={"video_dimension", "video_bitrate"})
 *    }
 * )
 * @Entity
 */

See @UniqueConstraint
