为什么我的用户和优惠券对象在创建新记录时不会保存到数据库中？
我正在使用typo3 v 4.5.30并进行一些扩展（我的第一次）管理一些优惠券。当我创建优惠券时，我保存创建者（前端用户）并将其正确保存到数据库中。但是，当我为优惠券用户执行相同的操作时，用户（和优惠券）不会保存到数据库。考虑这个代码片段，它试图将用户和优惠券保存在usedcoupon表中。 usedcoupon表基本上只有2列用于用户，1列用于优惠券。
为了获得一个usedcoupon对象，我调用了objectmanagers create方法。我已经拥有的用户和优惠券对象，并在我var_dump它们时看起来正确。即使我从usedcoupon对象中获取它们，它们看起来还可以，但即使创建了新记录，它们也不会保存到db。这段代码在我的CouponController中的一个动作方法中。
$used = $this->objectManager>create('Tx_BpsCoupons_Domain_Model_UsedCoupon');
$used->setCoupon($coupon);
$used->setUser($user);
$used->setGuest("myemail@ddd.com");
$userx = $used->getUser();
$coupx = $used->getCoupon();
/// var_dumps of userx and coupx show good objects
$this->usedCouponRepository->add($used);
//after this I can examine the db and see the new record but the user and coupon fields are empty, and no errors are seen

PPPS：我尝试为电子邮件地址添加基本文本字段，但事实证明它们也没有被保存。我原以为问题是用户和优惠券提交是对其他表中行的引用，但现在事实证明，更简单的事情也不会被保存。

答案 0 :(得分：1)
如果发生这种情况，很可能您的对象不会被持久化。通常，Extbase会在请求结束后持续更改对象。但是如果你是将您的响应作为JSON返回，然后退出操作，不会调用persistenceManager。
您可以通过将persistenceManager注入控制器来手动持久保存：
/**
* @var Tx_Extbase_Persistence_Manager
*/
protected $persistenceManager;
/**
* @param Tx_Extbase_Persistence_Manager $persistanceManager
* @return void
*/
public function injectPersistenceManager(Tx_Extbase_Persistence_Manager $persistenceManager) {
$this->persistenceManager = $persistenceManager;
}
然后在添加新对象后调用它：
$persistenceManager->persistAll();
在TYPO3 4.7+中，您可以使用$ persistenceManager的doc注释中的@inject注释来注入persistenceManager，而不需要注入函数。
如果这不能解决问题，可能是您的TCA存在问题。
