教义和复合唯一键 [英] Doctrine and composite unique keys

问题描述

我想在教义中做复合唯一键。
这些是我的字段：

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;

如何显示原则，那些组合在一起的是复合唯一键？

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

推荐答案

回答问题：

use Doctrine\ORM\Mapping\UniqueConstraint;

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

请参阅 @ UniqueConstraint
