Sylius覆蓋產品完整性約束違規

Question

我正在嘗試覆蓋產品捆綁包，但成功完成，但是在嘗試刪除將產品作為子產品的父實體時遇到錯誤

這是映射文件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>

這是我的product.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>

在WeShop \\ Bundle \\ BoutiqueBundle \\ Entity \\ Boutique中，我確實有

<?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，我確實有這個

<?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;
    }
}

與精品實體（商店）合作，我可以按照我希望一切正常的方式進行操作，現在的問題是當我嘗試刪除它時

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`))

請注意，一家精品店（商店）可以有多個產品，但是一個產品只能是一個精品店（商店）的子產品

我確實有一個具有相同邏輯的文檔包，並且當我嘗試刪除精品店時（知道表sylius_product中沒有引用精品店{null}的行），文檔被刪除了

這是我的文檔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">

    </id>
    <field name="intitule" type="string" column="intitule" length="255"/>
    <field name="url" type="string" column="url" length="255"/>
    <many-to-one field="boutique" target-entity="WeShop\Bundle\BoutiqueBundle\Entity\Boutique" inversed-by="documents">

    </many-to-one>
  </entity>
</doctrine-mapping>

先感謝您

Answer 1

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`))如果我理解現在，這是針對此錯誤的解決方案。

1. 您在sylius_product <=> weshop_boutique之間有關系。 因此，當您創建產品時， weshop_boutique id weshop_boutique到sylius_product表。

2. 所以，當你想刪除的東西weship_boutique這與關系sylius_product那么首先你要刪除產品sylius_product這與關系weship_boutique后，它會正常工作。

3. 例如

     => you have one field in "weship_boutique" table where "id = 1". => you have one field in "sylius_product" table where "boutique_id = 1". => so when you would like to delete field from "weship_boutique" table where "id = 1" at the same time "sylius_product" need it because you have foreign key relation between (boutique_id) of table sylius_product and (id) of table "weship_boutique". 

因此，首先從sylius_product中刪除產品（標識為weship_boutique），然后嘗試從weship_boutique中刪除字段。
