从父表Doctrine中删除记录

Question

我有两个实体 entityA.php和entityB.php

entityA.php

/**
 *
 * @ORM\Table(name="mytable")
 * @ORM\InheritanceType("JOINED")
 * @ORM\DiscriminatorColumn(name="discr", type="string")
 * @ORM\DiscriminatorMap({
 *          "foo"                        = "ACME\myBundle\Entity\entityB",
 * })
 * @ORM\Entity(repositoryClass="ACME\myBundle\Entity\entityARepository")
 */
class entityA
{
..more code

entityB.php

/**
 *
 * @ORM\Table(name="mytable_b")
 * @ORM\Entity(repositoryClass="ACME\myBundle\Entity\entityBRepository")
 */
class entityB extends entityA
{

我想删除对象表单entityB和（不查询）也删除entityA

如果我删除表单entityA“自动”删除表单entityB但没有反之亦然

您可以使用postRemove实体监听器设置到您的enetityB来删除父实体。 http://docs.doctrine-project.org/en/latest/reference/events.html#entity-listeners-class
