Database 为什么在typo3扩展中将对象保存到数据库时遇到问题？

为什么在创建新记录时，我的用户和优惠券对象不会保存到数据库中

我正在使用Typo3V4.5.30，并做了一些扩展（我的第一次）来管理一些优惠券。当我创建优惠券时，我保存创建者（frontenduser）并将其正确保存到DB。但是当我为优惠券用户做同样的事情时，用户（和优惠券）不会被保存到数据库中。考虑这个代码FRAG，它试图在使用的优惠券表中保存用户和优惠券。UsedConon表基本上只有两列，一列用于用户，另一列用于优惠券

为了获得UsedCoon对象，我调用了ObjectManager创建方法。我已经拥有的用户和优惠券对象，在我将它们转储时看起来是正确的。即使当我从UsedCoon对象获取它们时，它们看起来还可以，但即使创建了新记录，它们也不会保存到数据库中。此代码位于我的CouponController中的action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

谢谢

PS这是我从usedcoon.php获得的TCA

购买力平价：我试着为电子邮件地址添加一个基本的文本字段，但结果证明它们也没有被保存。我原以为问题在于用户和优惠券字段是对其他表中行的引用，但现在发现更简单的东西也不会被保存

如果发生这种情况，很可能您的对象没有持久化。通常，Extbase会在请求结束后保存对对象的更改。但是，如果您以JSON的形式返回响应，然后退出操作，则不会调用persistenceManager

您可以通过将persistenceManager注入控制器来手动持久化：

/**
* @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，您可以在$persistenceManager的文档注释中使用@inject注释来注入persistenceManager，而不需要注入函数

---

如果这不能解决问题，那么您的TCA可能有问题。

您是否在UsedCupons表中为您的字段设置了propper TCA配置？可能没有，但我尝试过调整它，我无法将其添加到extension builder中的扩展中，因为每当我尝试保存时，它都会崩溃。所以我在一个新的扩展中创建了这个模型，并试图复制它。我将用TCA更新我的Q。在Q中更新了一点我的TCA。但仍然不工作。直到明天…最好向我们展示您的

Tx\u bpshopons\u Domain\u Model\u usedcoon

作为一般性评论：您认为有必要拥有一个模型“优惠券”和“usedcoon”吗？如果只有一个模型的“优惠券”带有使用过的布尔值或使用过的日期和“使用过的用户”不是更好吗？嗨，Lorenz，现在尝试了，但仍然没有运气。记录会像以前一样保存，并且用户和优惠券字段为空。是的，它在我的UsedCoon tca中，拼写错误-tx_bpshoupon。。。应该是tx_BPSChopons。。。
