Php 删除一家公司的自我参照原则
你好,我对我的symfony项目有问题 我有一个监听器实体Php 删除一家公司的自我参照原则,php,symfony,testing,doctrine-orm,doctrine,Php,Symfony,Testing,Doctrine Orm,Doctrine,你好,我对我的symfony项目有问题 我有一个监听器实体 /** * Listener * * @ORM\Entity(repositoryClass="AppBundle\Entity\ListenerRepository") * @ORM\Table("listeners", uniqueConstraints={@ORM\UniqueConstraint(name="sponsor_code", columns={"sponsor_code"})}) * @ORM\HasLif
/**
* Listener
*
* @ORM\Entity(repositoryClass="AppBundle\Entity\ListenerRepository")
* @ORM\Table("listeners", uniqueConstraints={@ORM\UniqueConstraint(name="sponsor_code", columns={"sponsor_code"})})
* @ORM\HasLifecycleCallbacks()
*/
class Listener implements ListenerInterface
{
...
}
在这个类中有一个sponsoredListeners属性
/**
* @Groups({"listener_sponsored"})
*
* @ORM\OneToMany(targetEntity="Listener", mappedBy="sponsor")
*/
private $sponsoredListeners;
此属性是侦听器实体(当前类)的名称
侦听器使用此方法添加到此数组集合中
/**
* Add sponsored Listener
*
* @param \AppBundle\Entity\Listener $sponsoredListener
*
* @return Listener
*/
public function addSponsoredListener(\AppBundle\Entity\Listener $sponsoredListener)
{
if (!$this->sponsoredListeners->contains($sponsoredListener)) {
$this->sponsoredListeners[] = $sponsoredListener;
}
$sponsoredListener->setSponsor($this); // just set the sponsor property for the listener given in parameters of this function (addSponsoredListener)
return $this;
}
问题是,当我在测试期间试图从侦听器表中删除所有侦听器时,我会遇到这些错误
SQLSTATE[23000]: Integrity constraint violation: 1451 Cannot delete or update a parent row: a foreign key constraint fails (`myradio_test`.`listeners`, CONSTRAINT `FK_CEFB12DB12F7FB51` FOREIGN KEY (`sponsor_id`) REFERENCES `listeners` (`id`))

如果我知道发生了什么,他正在试图删除与其他监听器“链接”的监听器,以获得赞助的监听器
我想我需要一个级联删除,但不知道怎么做。如果有人能给我解释,那会很酷
这是listener表
列类型注释
id int(11)自动递增帐户id int(11)NULL
赞助商id int(11)NULL
站点id int(11)NULL
firstname varchar(100)NULL
性别varchar(255)NULL
出生年份整数(11)空
picture varchar(255)NULL
赞助商代码varchar(6)
在datetime为空时发起的\u
在datetime创建\u
更新了\u at datetime NULL对于类属性,您需要删除set annotation onDelete=“set NULL”并使其可为NULL如果需要更多详细信息,请告诉我
