Symfony2.8 - 缺少标识符 id
Symfony2.8 - The identifier id is missing
我正在开发一个基于 symfony2.8 的网站，允许用户购买产品。我在处理购物车时一直遇到问题。这是返回的错误：

有什么建议吗？
find() 方法¹ 将 id 作为参数，因此以下代码看起来是错误的：
$commande = $em->getRepository('MainBundle:Commande')->find($session->get('commande'));
您必须检查 $session->get('commande') 返回的是一个整数，并且它对应于 Article 的 id 之一。
如果您的代码，commande 是一个实体，同时该实体的 属性 是一个数组。您可能应该重命名对象和变量以避免混淆。
的快捷方式
我发现，在 CartController::prepareCommandeAction() 中，我没有把 $em->flush() 放在正确的位置。这就是 prepareCommandeAction() 总是返回 null 的原因，因为 $commande->getId() 等于 null。以下是我应该做的：
public function prepareCommandeAction()
{
$session = $this->getRequest()->getSession();
$em = $this->getDoctrine()->getManager();
if (!$session->has('commande')) {
$commande = new Commande();
dump($commande);die();
$commande->setDate(new \DateTime());
$commande->setUser($this->container->get('security.context')->getToken()->getUser());
$commande->setValider(0);
$commande->setReference(0);
$commande->setCommande($this->facture());
$em->persist($commande);
$em->flush();
$session->set('commande', $commande->getId());
} else {
$commande = $em->getRepository('MainBundle:Commande')->find($session->get('commande'));
}
return $commande->getId();
}

有什么建议吗？
find() 方法¹ 将 id 作为参数，因此以下代码看起来是错误的：
$commande = $em->getRepository('MainBundle:Commande')->find($session->get('commande'));
您必须检查 $session->get('commande') 返回的是一个整数，并且它对应于 Article 的 id 之一。
如果您的代码，commande 是一个实体，同时该实体的 属性 是一个数组。您可能应该重命名对象和变量以避免混淆。
我发现，在 CartController::prepareCommandeAction() 中，我没有把 $em->flush() 放在正确的位置。这就是 prepareCommandeAction() 总是返回 null 的原因，因为 $commande->getId() 等于 null。以下是我应该做的：
public function prepareCommandeAction()
{
$session = $this->getRequest()->getSession();
$em = $this->getDoctrine()->getManager();
if (!$session->has('commande')) {
$commande = new Commande();
dump($commande);die();
$commande->setDate(new \DateTime());
$commande->setUser($this->container->get('security.context')->getToken()->getUser());
$commande->setValider(0);
$commande->setReference(0);
$commande->setCommande($this->facture());
$em->persist($commande);
$em->flush();
$session->set('commande', $commande->getId());
} else {
$commande = $em->getRepository('MainBundle:Commande')->find($session->get('commande'));
}
return $commande->getId();
}
