作为symfony2和querybuilder的新手,我试图选择所有容器,但只将结果限制为登录用户可以访问的容器。
使用当前代码我收到此错误:
注意:未定义的索引:/var/www/biztv_symfony/vendor/doctrine/lib/Doctrine/ORM/Query/SqlWalker.php第746行中的容器
以下是我对查询的尝试(我已经尝试过这个和其他论坛网站的几个选项,但似乎仍然无法理解...)
public function indexAction()
{
//Get the requisits
$companyId = $this->container->get('security.context')->getToken()->getUser()->getCompany()->getId();
$em = $this->getDoctrine()->getEntityManager();
//Fetch the containers
$repository = $this->getDoctrine()->getRepository('BizTVContainerManagementBundle:Container');
$query = $repository->createQueryBuilder('c')
->innerJoin('c.users','u')
->where('c.company = :company')
->setParameter('company', $companyId)
->orderBy('c.name', 'ASC')
->getQuery();
$containers = $query->getResult();
我通过多对多关系跟踪访问,这是我的用户实体......
<?php
// src/BizTV/UserBundle/Entity/User.php
namespace BizTV\UserBundle\Entity;
use FOS\UserBundle\Entity\User as BaseUser;
use Doctrine\ORM\Mapping as ORM;
use BizTV\BackendBundle\Entity\company as company;
/**
* @ORM\Entity
* @ORM\Table(name="fos_user")
*/
class User extends BaseUser
{
/**
* @ORM\Id
* @ORM\Column(type="integer")
* @ORM\GeneratedValue(strategy="AUTO")
*/
protected $id;
/**
* @var object BizTV\BackendBundle\Entity\company
*
* @ORM\ManyToOne(targetEntity="BizTV\BackendBundle\Entity\company")
* @ORM\JoinColumn(name="company", referencedColumnName="id", nullable=false)
*/
protected $company;
/**
* @ORM\ManyToMany(targetEntity="BizTV\ContainerManagementBundle\Entity\Container", inversedBy="User")
* @ORM\JoinTable(name="access")
*/
private $access;
public function __construct()
{
parent::__construct();
$this->access = new \Doctrine\Common\Collections\ArrayCollection();
}
//getters and setters...
这是我的容器实体:
<?php
namespace BizTV\ContainerManagementBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
use Symfony\Component\Validator\Constraints as Assert;
use BizTV\UserBundle\Entity\User as user;
/**
* BizTV\ContainerManagementBundle\Entity\Container
*
* @ORM\Table(name="container")
* @ORM\Entity
*/
class Container
{
/**
* @var integer $id
* @ORM\Id
* @ORM\Column(type="integer")
* @ORM\GeneratedValue(strategy="AUTO")
*/
protected $id;
/**
* @var string $name
* @Assert\NotBlank(message = "Du måste ange ett namn för området")
* @ORM\Column(name="name", type="string", length=255)
*/
private $name;
//TODO: form handler assuring no name is used twice in same company
/**
* @var object BizTV\BackendBundle\Entity\company
*
* @ORM\ManyToOne(targetEntity="BizTV\BackendBundle\Entity\company")
* @ORM\JoinColumn(name="company", referencedColumnName="id", nullable=false)
*/
protected $company;
/**
* @ORM\ManyToMany(targetEntity="BizTV\UserBundle\Entity\User", mappedBy="Container")
*/
private $users;
public function __construct() {
$this->users = new \Doctrine\Common\Collections\ArrayCollection();
}
答案 0 :(得分:3)
在Container
实体中,当您指定$users
属性映射时,mappedBy
的值很重要:您需要指定名称 User
类中的反向属性。
在这里,我们有Container::$users
&lt; - &gt; User::$access
。
将注释更改为:
class User
{
/**
* @ORM\ManyToMany(targetEntity="BizTV\ContainerManagementBundle\Entity\Container", inversedBy="users")
* @ORM\JoinTable(name="access")
*/
private $access;
}
class Container
{
/**
* @ORM\ManyToMany(targetEntity="BizTV\UserBundle\Entity\User", mappedBy="access")
*/
private $users;
}
我建议您阅读doctrine orm documentation part about associations,并在所有关联中验证并解决此问题。
