学说 2 ORM\GeneratedValue(strategy="AUTO") 不起作用

Question

我将 doctrine 2 与 symfony3 和 PostgresSQL 数据库一起使用，我在插入值时遇到问题，因为 id 没有递增 anymore.I 已更新数据库：

php app/console doctrine:database:update --dump-sql
php app/console doctrine:schema:update --force

但是：我得到了

Nothing to update - your database is already in sync with the current entity metadata.

这是我的 class 类别：

class Categorie {
/**
 * @var int
 * @ORM\Column(name="id", type="integer")
 * @ORM\Id
 * @ORM\GeneratedValue(strategy="AUTO")
 */
private $id;

/**
 * @var string
 * @ORM\Column(name="nom", type="string", length=255 , nullable=true)
 */
private $nom;

/**

 *
 * @ORM\Column(name="niveau", type="integer" , nullable=true)
 */
private $niveau;

/**

private $ordre;

}

当我尝试使用插入 sql 命令将数据插入数据库时：

INSERT INTO public.categorie(nom, niveau, ordre)
VALUES ('test',1,1);

我收到这个错误：

ERREUR: une valeur NULL viole la contrainte NOT NULL de la colonne « id »

感谢您的帮助

Answer 1

我通过在实体 class

中将 "AUTO" 更改为 "IDENTITY" 解决了我的问题

* @var int
* @ORM\Column(name="id", type="integer")
* @ORM\Id
* @ORM\GeneratedValue(strategy="IDENTITY")
*/
private $id;
