我在渲染模板期间的代码有问题。我正在尝试执行一对多双向，但仍然有此错误：
呈现模板期间引发异常 （"注意：未定义的索引：设备"）
我给你我的代码这是我的类"Equipe"反面：
/**
* @ORMOneToMany(targetEntity="projetchMauleonBundleEntityEquipe", mappedBy="equipe")
*/
private $services;
这是我的类"服务"拥有方：
/**
* @ORMManyToOne(targetEntity="projetchMauleonBundleEntityEquipe", inversedBy="services")
* @ORMJoinColumn(nullable=true)
*/
private $equipe;
这是我的观点：

public function menuAction()
{
$em=$this->getDoctrine()->getManager();
$repositoryEquipe = $em->getRepository('projetchMauleonBundle:Equipe');
$tabEquipes = $repositoryEquipe->findAll();
return $this->render('projetchMauleonBundle:Mauleon:menu2.html.twig', array('tabEquipes'=>$tabEquipes));
}
您在实体Equipe中的targetEntity似乎有问题
/**
* @ORMOneToMany(targetEntity="projetchMauleonBundleEntityService", mappedBy="equipe")
*/
private $services;
而不是
/**
* @ORMOneToMany(targetEntity="projetchMauleonBundleEntityEquipe", mappedBy="equipe")
*/
private $services;
