我想从Sylius ProductBundle更改the spread operator。所以我创建了一个<?php
namespace App\Symfony\EventListener\Sylius;
use Sylius\Component\Product\Model\Product;
use Doctrine\Common\EventSubscriber;
use Doctrine\Common\Persistence\Mapping\ClassMetadata;
use Doctrine\ORM\Event\LoadClassMetadataEventArgs;
/**
* Remove the reference of a Variant from its parent (Product) without delete it
*/
class ProductLoadMetadataSubscriber implements EventSubscriber
{
/**
* @return array
*/
public function getSubscribedEvents()
{
return array(
'loadClassMetadata',
);
}
/**
* @param LoadClassMetadataEventArgs $eventArgs
*/
public function loadClassMetadata(LoadClassMetadataEventArgs $eventArgs)
{
/** @var ClassMetadata $metadata */
$metadata = $eventArgs->getClassMetadata();
if (Product::class !== $metadata->name) {
return;
}
// Property "variants" in "Sylius\Component\Product\Model\Product" was already declared, but it must be declared only once
$metadata->mapOneToMany([
'fieldName' => 'variants',
'targetEntity' => 'Sylius\Component\Product\Model\VariantInterface',
'mappedBy' => 'object',
'orphanRemoval' => false
]);
//$variantsMapping = $metadata->getAssociationMapping('variants');
//$variantsMapping['orphanRemoval'] = false;
}
}
事件的监听器：
orphanRemoval我的目标是将false字段的variants选项值设置为variants。
但是我没有找到更新ClassMetadataInfo实例的方法或其他东西。
目前我有这个错误：
“Sylius \ Component \ Product \ Model \ Product”中的属性“variants”是 已经声明，但必须只声明一次
这是合乎逻辑的，因为unset($metadata->associationMappings['variants']['orphanRemoval']);
// setAssociationOverride doesn't handle 'orphanRemoval' but it calls internally _validateAndCompleteOneToManyMapping
// which set orphanRemoval to false by default
$metadata->setAssociationOverride('variants', []);
字段已经存在。
编辑：
我尝试了另一件事，但没有成功：
$.ajax({
url: "testOperation.php",
async: false,
data: compareHeure,
success: function (data, statusRequest) {
})
答案 0 :(得分：0)
要设置orphanRemoval，您可以尝试以下代码段：
if (SomeClass::class === $metadata->getName()) {
if (isset($metadata->associationMappings['itemShippingTrackings'])) {
$metadata->associationMappings['itemShippingTrackings']['orphanRemoval'] = false;
}
}
