然后我想显示一个与托儿所经理（员工role = ROLE_MANAGER）相关的所有托儿所的下拉菜单，所以我有控制器：
<?php
namespace VS\CrmBundle\Controller;

use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Symfony\Component\HttpFoundation\Request;
use VS\CrmBundle\Entity\Staff;
use VS\CrmBundle\Form\StaffType;
class ManagerController extends Controller
{
public function dashboardAction($nursery_id)
{
$currentUser = $this->get('security.token_storage')->getToken()->getUser();
$nurseryRepo = $this->getDoctrine()->getRepository('VSCrmBundle:Nursery');
$nursery = $nurseryRepo->findOneBy(array(
'id' => $nursery_id,
'staff' => $currentUser
));
if(!$nursery)
{
throw $this->createNotFoundException("The nursery has not been found or you are not allowed to access it.");
}
return $this->render("VSCrmBundle:Manager:dashboard.html.twig", array(
'nursery' => $nursery
));
}
}
我可以在视图中显示我的下拉列表：
<li class="dropdown">
<a href="#" class="dropdown-toggle" data-toggle="dropdown" role="button" aria-haspopup="true" aria-expanded="false">Dashboards<span class="caret"></span></a>
<ul class="dropdown-menu">
{% if is_granted('ROLE_MANAGER') %}
<li class="dropdown-header">Nurseries</li>
{% for nursery in app.user.nurseries %}
<li><a href="{{ path('vs_crm_manager_dashboard', {'nursery_id' : nursery.id}) }}">{{ nursery.name }} dashboard</a></li>
{% endfor %}
{% endif %}
</ul>
</li>
但是当我点击一个随机的托儿所时，我有错误：

那么我做错了什么？也许这样做是错的？
答案 0 :(得分：2)
请添加具有相对列名的joinColumns和inverseJoinColumns。
<强> Staff.php
/**
* @var ArrayCollection
*
* @ORM\ManyToMany(targetEntity="Nursery", inversedBy="staff", cascade={"persist"})
* @ORM\JoinTable(name="nursery_staff",
* joinColumns={@ORM\JoinColumn(name="nursery_id", referencedColumnName="id")},
* inverseJoinColumns={@ORM\JoinColumn(name="staff_id", referencedColumnName="id")}
* )
*/
private $nurseries;
答案 1 :(得分：1)
通过更改控制器解决了问题：
public function dashboardAction($nursery_id)
{
//$currentUser = $this->get('security.token_storage')->getToken()->getUser();
$nurseryRepo = $this->getDoctrine()->getRepository('VSCrmBundle:Nursery');
$nursery = $nurseryRepo->findOneBy(array('id' => $nursery_id));
if(!$nursery)
{
throw $this->createNotFoundException("The nursery has not been found or you are not allowed to access it.");
}
return $this->render("VSCrmBundle:Manager:dashboard.html.twig", array(
'nursery' => $nursery
));
}
如果您使用findOneBy关联中的属性进行搜索，我认为ManyToMany方法不起作用。
