为什么我无法以typo3 扩展名将对象保存到数据库中？

Question

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typo3 v 4.5.30 并做了一个小扩展（我的第一个）来管理一些优惠券。当我创建优惠券时，我会保存创建者（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做同样的事情时，该用户（和优惠券）不会保存到数据库中。考虑这段代码片段，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，一列用于用户，一列用于优惠券。

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在我 var_dump 时看起来正确。即使我从 usedcoupon 对象中获取它们，它们看起来还不错，但即使创建了新记录，它们也不会保存到数据库中。此代码在我的 CouponController 中的一个操作方法中。

             $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

谢谢

PPPS：我尝试为电子邮件地址添加一个基本文本字段，但结果它们也没有保存。我原以为问题在于用户和优惠券文件是对其他表中行的引用，但现在事实证明更简单的东西也没有保存。

Answer 1

如果发生这种情况，很可能您的对象没有持久化。通常，Extbase 会在请求结束后保留​​对对象的更改。但是如果你例如以 JSON 格式返回您的响应，然后退出您的操作，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，可以使用$persistenceManager的doc注释中的@inject注解来注入persistenceManager，不需要注入函数。

如果这不能解决问题，则可能是您的 TCA 有问题。
