我写了一个问询,我不得不在一张带有理论的表格中发现最后插入项目的识别。
我不得不:
$this->getDoctrine()->getConnection()->prepare("SELECT MAX(id) FROM Commit");

When you flush, Doctrine will assign the entity id to your entity. Let say your entity is:
class MyEntity {
protectd $id;
public function getId() {
return $this->id;
}
public function setId($id) {
$this->id = $id;
}
}
当你做实体管理:面粉,最后插入 d 将被分配到补贴财产。 然后,你只花了两美元,然后用上了上门。
正如Cerad所言,你真的要找回自己的实体,做另一个问询。 相反,你可以让实体经理(最新)知道自己的身份。 例如。
$myEntity = new EntitiesMyEntity();
$myEntity->setProperty($someValue);
// Save my entity ($em = EntityManager)
$em->persist($myEntity);
// Flush my entity manager
try {
$em->flush();
} catch (Exception $e)
{
}
// Refresh my entity (populate the identifier)
$em->refresh($myEntity);
// Tada
echo $myEntity->getId();
理论没有这样做的任何方法,只有最近才投入使用,只有插入的使用者才能使用。 但是,如果你不想质疑这一表格,因为它是一片大事,或者是因为其他东西,你可以再做一表来储存这种id,并更新一点,即某些用户每增加一个新内容。 如果你不想这样做,那么你就必须这样做。
