我有父子实体。删除所有子实体后，symfony 也删除我的父实体。我不喜欢这种行为，无论是否有孩子，父实体都必须存在。这是我的父母代码：
/**
* @OneToMany(targetEntity="Gallery", mappedBy="promotion", cascade={"persist", "remove"})
*/
private $galleries;
public function __construct() {
$this->galleries = new ArrayCollection();
}
public function getGalleries() {
return $this->galleries;
}
public function addGallery($gallery)
{
$gallery->setPromotion($this);
$this->galleries[] = $gallery;
return $this;
}
public function removeGallery($gallery)
{
$gallery->setPromotion(null);
$this->galleries->removeElement($gallery);
}
在这里为孩子：
/**
* @ManyToOne(targetEntity="Promotion", inversedBy="galleries")
*/
private $promotion;
我不知道该怎么办，我已经花了几个小时在这上面。
它由简单的管理包处理，所以它不会帮助你：
