Question

我正在使用带有symfony3和PostgresSQL数据库的doctrine 2，我在插入值时遇到问题，因为id不再增加。我已用以下内容更新数据库：

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.

这是我的班级类别：

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

/**

}

我尝试使用insert sql命令将数据插入数据库：

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

我收到了这个错误：

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

感谢您的帮助

Answer 1

我通过改变＆＃34; AUTO＆＃34;解决了我的问题。通过＆＃34; IDENTITY＆＃34;在实体类

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

Doctrine 2 ORM \ GeneratedValue（策略=＆＃34; AUTO＆＃34;）不起作用
