我正在开发一个基于symfony2.8的网站，允许用户购买产品。我一直遇到一个试图处理购物车的问题。这是返回的错误：
MainBundle \ Entity \ Commande
的查询缺少标识符ID

这里你有CartController类，我的MainBundle \ CartController只有相关的方法：
<form action="{{ path('validation') }}" method="POST">
<h4>Adresse de livraison</h4>
{% for address in currentUser.addresses %}
<label class="radio">
<input type="radio" name="shipping" value="{{ address.id }}" {% if loop.index0 == 0 %} checked="checked"{% endif %} />
{{ address.streetnumber }} {% if address.streetextension is defined and address.streetextension is not null %}{{ address.streetextension }}{% endif %} {{ address.streettype }} {{ address.streetname }}, {{ address.zipcode }} {{ address.city }} - {{ address.country }}<a href="{{ path('deleteAddress', {'id':address.id}) }}"><i class="glyphicon glyphicon-trash"></i></a>
</label>
{% endfor %}
<br><br>
<h4>Adresse de facturation</h4>
{% for address in currentUser.addresses %}
<label class="radio">
<input type="radio" name="billing" value="{{ address.id }}" {% if loop.index0 == 0 %} checked="checked"{% endif %} />
{{ address.streetnumber }} {% if address.streetextension is defined and address.streetextension is not null %}{{ address.streetextension }}{% endif %} {{ address.streettype }} {{ address.streetname }}, {{ address.zipcode }} {{ address.city }} - {{ address.country }}<a href="{{ path('deleteAddress', {'id':address.id}) }}"><i class="glyphicon glyphicon-trash"></i></a>

{% endfor %}
<button class="btn btn-primary">Valider mes adresses</button>
</form>
这是从中调用validationAction（）方法的twig代码：

有什么建议吗？
答案 0 :(得分：1)
find()方法¹将id作为参数，因此以下代码看起来不正确：
$commande = $em->getRepository('MainBundle:Commande')->find($session->get('commande'));
您必须检查$session->get('commande')返回的整数是否与id的{{1}}之一相对应。
如果您的代码是Article，则它是一个实体，同时也是该实体的属性，它是一个数组。您应该重命名对象和变量，以避免混淆。
答案 1 :(得分：0)
我发现在CartController :: prepareCommandeAction（）中，我没有将$em->flush()放在正确的位置。这就是为什么prepareCommandeAction（）总是返回null的原因，因为$ commande-> getId（）等于null。以下是我应该做的事情：
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();
}
