重用 Doctrine_Record 对象来保存模型的多个实例

我正在 Symfony 应用程序中开发某种通知模块。我正在迭代用户的Doctrine_Collection，为每个在其个人资料中具有活动标志的用户创建一个通知：

// Create and define common values of notification
$notification = new Notification();
$notification->setField1('...');
$notification->setField2('...');
...

// Post notification to users
foreach ( sfGuardUserTable::getInstance()->findByNotifyNewOrder(true) as $user ) {
  $notification->setUserId($user->getId());
  $notification->save();
}

问题是，一旦我保存了第一个通知，我就无法重用该对象以在数据库中存储新记录。我已尝试使用 null 和 '' 来 $notification->setId() ，但保存会更新对象而不是保存新对象。

有没有办法重用 $notification 对象？我想这样做，因为通知字段创建的逻辑有点复杂。

I am working on some kind of notifications module in a Symfony application. I am iterating over a Doctrine_Collection of users to create a Notification for every user that has a flag active in its profile:

// Create and define common values of notification
$notification = new Notification();
$notification->setField1('...');
$notification->setField2('...');
...

// Post notification to users
foreach ( sfGuardUserTable::getInstance()->findByNotifyNewOrder(true) as $user ) {
  $notification->setUserId($user->getId());
  $notification->save();
}

Problem is that once I have saved the first notification I cannot reuse the object to store new records in the database. I have tried $notification->setId() with null and '', but saving updates the object instead of saving a new.

Is there a way to reuse the $notification object? I would like to do that because logic of notification fields creation is a bit complex.

复制是什么你正在寻找。

// Create and define common values of notification
$notification = new Notification();
$notification->setField1('...');
$notification->setField2('...');
...

// Post notification to users
foreach ( sfGuardUserTable::getInstance()->findByNotifyNewOrder(true) as $user ) {
  $newNotification = $notification->copy();
  $newNotification->setUserId($user->getId());
  $newNotification->save();
}

Copy is what you're looking for.

// Create and define common values of notification
$notification = new Notification();
$notification->setField1('...');
$notification->setField2('...');
...

// Post notification to users
foreach ( sfGuardUserTable::getInstance()->findByNotifyNewOrder(true) as $user ) {
  $newNotification = $notification->copy();
  $newNotification->setUserId($user->getId());
  $newNotification->save();
}
