Doctrine和复合唯一键

Question

我想在学说中做复合唯一键.那些是我的领域:

/**
 * @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;

我如何展示学说,那些结合在一起的是复合的唯一关键？

Answer 1

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

Answer 2

如果有人想使用PHP 8 属性而不是 Doctrine 注释：

use Doctrine\ORM\Mapping as ORM;

#[ORM\Entity]
#[ORM\UniqueConstraint(
  name: 'video_unique_idx',
  columns: ['video_dimension', 'video_bitrate']
)]

Answer 3

我发现它只对useORM 更加冗长,然后ORM在注释中添加前缀.另请注意,您可以将注释拆分为多行以使其更具可读性,尤其是如果您有几个要提及的项目(在下面的示例中为索引).

use Doctrine\ORM\Mapping as ORM;

/**
 * VideoSettings
 *
 * @ORM\Cache(usage="NONSTRICT_READ_WRITE")
 * @ORM\Entity(repositoryClass="AppBundle\Repository\VideoSettingsRepository")
 * @ORM\Table(name="emails", uniqueConstraints={
 *      @ORM\UniqueConstraint(name="dimension_bitrate", columns={"video_dimension", "video_bitrate"})
 * }, indexes={
 *      @ORM\Index(name="name", columns={"nane"})
 * })
 */
class VideoSettings
