为什么克隆具有关联的 Doctrine 实体会导致一个额外的 INSERT？
[英]Why does cloning a Doctrine entity with associations result in one extra INSERT?
问题描述

最终目标是克隆 ISV-Here\App-Name-Here\Doctrine\Entities\RmtkOrders 的实例及其关联。 我已经实现了 __clone() 如下：
class Orders
{
.....
public function __clone()
{
if ($this->ordersId) {
unset($this->ordersId);
$nonTangibleItems = new ArrayCollection();
foreach ($this->nonTangibleItems as $nonTangibleItem) {
$nonTangibleItemClone = clone $nonTangibleItem;
$nonTangibleItemClone->setOrder($this);
$nonTangibleItems->add($nonTangibleItemClone);
}
$this->nonTangibleItems = $nonTangibleItems;
}
}
}
}
我的controller如下：
/**
* @var RmtkOrders $rmtkOrder
*/
$rmtkOrder = $this->entityManager->find(DOCTRINE_ENTITIES_NAMESPACE . 'RmtkOrders', 123456);
$rmtkOrder->setOrdersId2('das' . time());
$rmtkOrder->setInvoice(null);
$rmtkOrder->setTangibleItems(new ArrayCollection());
$rmtkOrder->setVidrRecords(new ArrayCollection());
$rmtkOrder->setAddresses(new ArrayCollection());
$rmtkOrder->setScVatTaxReports(new ArrayCollection());
$rmtkOrder->setSpApiAfnRecords(new ArrayCollection());
$copy = clone $rmtkOrder;
$this->getEntityManager()->persist($copy);
try {
$this->getEntityManager()->flush($copy);
} catch (Exception $ex) {
Cli::doOutputLine($ex->getMessage());
}

2506366 Query INSERT INTO app-name-here.rmtk_orders_nontangibles (orders_id, on_id) VALUES (1893942, 1091050)
最后一个 INSERT 语句导致An exception occurred while executing a query: SQLSTATE[23000]: Integrity constraint violation: 1062 Duplicate entry '1091053' for key 'PRIMARY' 。 所有 rest 的 INSERT 语句都完全符合要求。
最后一个 INSERT 语句根本不应该存在。 您能找出问题所在以及执行最后一个 INSERT 语句的原因吗？

我不确定是否理解您的问题，因为听起来代码完全按预期工作（和失败）。 当您克隆 RmtkOrders 时，这是 doctrine 必须保留的新实体。
克隆 object 时，会设置一个具有相同属性的新对象。 所以，它失败了，因为初始实体已经有一个 id，而克隆的实体复制了这个 id。 当 Doctrine 试图存储它时，这个 id 违反了主键的唯一完整性约束。
在我看来，如果你想创建一个新的实体并存储它，你应该实现魔术方法__clone()来取消设置 RmtkOrders::id
public function __clone()
{
$this->id = null;
}
现在 doctrine 将在持久化时自动生成一个新的 id。
或者，如果需要，您可能必须以相同的方式克隆子实体。
public function __clone()
{
$this->id = null;
//the below code is necessary because __construct is NOT called by __clone
$this->setInvoice(null);
$this->setTangibleItems(new ArrayCollection());
$this->setVidrRecords(new ArrayCollection());
$this->setAddresses(new ArrayCollection());
$this->setScVatTaxReports(new ArrayCollection());
$this->setSpApiAfnRecords(new ArrayCollection());
}
你的 controller 变成：
/**
* @var RmtkOrders $rmtkOrder
*/
$rmtkOrder = $this->entityManager->find(DOCTRINE_ENTITIES_NAMESPACE . 'RmtkOrders', 123456);
$copy = clone $rmtkOrder;
$copy->setOrdersId2('das' . time()); //I don't understand this line, it could be move to __clone method
$this->getEntityManager()->persist($copy);
try {
$this->getEntityManager()->flush($copy);
} catch (Exception $ex) {
Cli::doOutputLine($ex->getMessage());
}
无论如何，我强烈建议您永远不要更新 $rmtkOrder，而只操作克隆的 $clone。 如果魔术 __clone 方法已用于另一个用例，我建议您使用 Model 模式。

您是否在克隆后尝试从实体管理器中分离您的新实例？
$this->getEntityManager()->detach($copy);
