Sylius 覆盖产品完整性约束冲突

我正在尝试覆盖产品捆绑包，我成功了，但在尝试删除将产品作为子级的父实体时出现错误

这是映射文件 product.orm.xml

<?xml version="1.0" encoding="UTF-8"?>
<doctrine-mapping xmlns="http://doctrine-project.org/schemas/orm/doctrine-mapping"
                  xmlns:gedmo="http://gediminasm.org/schemas/orm/doctrine-extensions-mapping">
    <mapped-superclass name="Sylius'Component'Product'Model'Product" table="sylius_product">
        <id name="id" column="id" type="integer">
            <generator strategy="AUTO" />
        </id>
        <field name="name" column="name" type="string">
            <gedmo:versioned />
        </field>
        ...
    </mapped-superclass>
</doctrine-mapping>

这是我的产品.orm.xml文件

<?xml version="1.0" encoding="UTF-8"?>
<doctrine-mapping xmlns="http://doctrine-project.org/schemas/orm/doctrine-mapping"
                  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
                  xsi:schemaLocation="http://doctrine-project.org/schemas/orm/doctrine-mapping
                                      http://doctrine-project.org/schemas/orm/doctrine-mapping.xsd">
    <entity name="WeShop'Bundle'CoreBundle'Entity'Product" table="sylius_product">
        <many-to-one field="boutique" target-entity="WeShop'Bundle'BoutiqueBundle'Entity'Boutique" inversed-by="produits">
            <join-column name="boutique_id" referenced-column-name="id" nullable="true" onDelete="SET NULL" />
        </many-to-one>
    </entity>
</doctrine-mapping>

in WeShop''Bundle''BoutiqueBundle''Entity''Boutique 我确实有

<?php
namespace WeShop'Bundle'BoutiqueBundle'Entity;
use Sylius'Component'Core'Model'ProductInterface as ProductInterface;
use Doctrine'ORM'Mapping as ORM;
use Doctrine'Common'Collections'ArrayCollection;
class Boutique
{
    private $produits;
    public function __construct(){
        $this->produits = new ArrayCollection();
    }
    public function getProduits(){
        return $this->produits;
    }
    public function setProduits(ProductInterface $produit){
        $this->produits[] = $produit;
        return $this;
    }
}

在WeShop''Bundle''CoreBundle''Entity''Product 中，我确实有这个

<?php
namespace WeShop'Bundle'CoreBundle'Entity;
use WeShop'Bundle'CoreBundle'Model;
use WeShop'Bundle'BoutiqueBundle'Entity'BoutiqueInterface as BoutiqueInterface;
use Sylius'Component'Core'Model'Product as BaseProduct;
class Product extends BaseProduct
{
    private $boutique;
    public function getBoutique()
    {
        return $this->boutique;
    }
    public function setBoutique(BoutiqueInterface $boutique = null)
    {
        $this->boutique = $boutique;
        return $this;
    }
}

使用精品实体(商店(，我可以按照我想要的方式操纵它，现在的问题是当我尝试删除它时，我得到

An exception occurred while executing 'DELETE FROM weshop_boutique WHERE id = ?' with params [2]:
SQLSTATE[23000]: Integrity constraint violation: 1451 Cannot delete or update a parent row: a foreign key constraint fails (`sylius_dev`.`sylius_product`, CONSTRAINT `FK_677B9B74AB677BE6` FOREIGN KEY (`boutique_id`) REFERENCES `weshop_boutique` (`id`))

请注意，一家精品店(商店(

可以有多个产品，但一个产品只能是一个精品店(商店(的子产品

我确实有一个具有相同逻辑的文档包，当我尝试删除精品店时(知道在表中没有引用精品店{null}sylius_product(，文档被删除

这是我的文档 orm XML 文件

<?xml version="1.0" encoding="utf-8"?>
