Php 关联映射实体删除检查

我有两个具有多对一关联映射的实体

<?php

namespace AppBundle\Entity;

use Doctrine\ORM\Mapping as ORM;
use Doctrine\Common\Collections\ArrayCollection;
/**

{
    /**

     * @ORM\GeneratedValue(strategy="AUTO")
     */
    private $shtId;

    /**
     * @ORM\Column(type="string", length=255)
     */
    private $shtName;

    /**
     * @ORM\Column(type="integer")
     */
    private $shtCreateuid;

    /**

    // ...

如何将``shtdelete`标志设置为1？是否直接调用setter
setShtDelete
？是通过表单完成的吗？不确定这个答案是否是您想要的，但您可以向ShopType:hasShops（）添加一个方法{return（bool）count（$this->shids）；}
<?php

namespace AppBundle\Entity;

use Doctrine\ORM\Mapping as ORM;


/**
 * @ORM\Table(name="Shop")
 * @ORM\Entity(repositoryClass="AppBundle\Repository\ShopRepository")
 */
class Shop
{
    /**
     * @ORM\Column(type="integer")
     * @ORM\Id
     * @ORM\GeneratedValue(strategy="AUTO")
     */
    private $shId;


     /**
     * Many Features have One Product.
     * @ManyToOne(targetEntity="ShopType", inversedBy="shids")
     * @JoinColumn(name="shtId", referencedColumnName="sht_id")
     */
    private $shtId;
