当我返回一个带关系的对象时,我想要排除一些属性。
例如,我有一个实体用户和相册,我只想在获得相册列表时公开用户名。
有可能吗?
这是我的相册实体:
<?php
namespace Billion\AlbumBundle\Entity;
use Billion\AlbumBundle\Entity\Media;
use Doctrine\ORM\Mapping as ORM;
/**
* Album
*
* @ORM\Table()
* @ORM\Entity
*/
class Album
{
/**
* @var integer
*
* @ORM\Column(name="id", type="integer")
* @ORM\Id
* @ORM\GeneratedValue(strategy="AUTO")
*/
private $id;
/**
* @var string
*
* @ORM\Column(name="name", type="string", length=255)
*/
private $name;
/**
* @var string
*
* @ORM\Column(name="longitude", type="string", length=255, nullable=true)
*/
private $longitude;
/**
* @var string
*
* @ORM\Column(name="latitude", type="string", length=255, nullable=true)
*/
private $latitude;
/**
* @ORM\OneToMany(targetEntity="Billion\AlbumBundle\Entity\Media", mappedBy="album")
**/
private $medias;
/**
* @ORM\OneToOne(targetEntity="Billion\UserBundle\Entity\Users")
* @ORM\JoinColumn(name="owner_id", referencedColumnName="id", nullable=false)
*/
private $owner;
/**
* @ORM\OneToOne(targetEntity="Billion\SecurityBundle\Entity\Visibility")
* @ORM\JoinColumn(name="visibility_id", referencedColumnName="id", nullable=false)
*/
private $visibility;
/**
* Constructor
*/
public function __construct()
{
$this->medias = new \Doctrine\Common\Collections\ArrayCollection();
}
}
我的用户实体:
namespace Billion\UserBundle\Entity;
use FOS\UserBundle\Model\User as BaseUser;
use Doctrine\ORM\Mapping as ORM;
/**
* Users
*
* @ORM\Table()
* @ORM\Entity
*/
class Users extends BaseUser
{
/**
* @var integer
*
* @ORM\Column(name="id", type="integer")
* @ORM\Id
* @ORM\GeneratedValue(strategy="AUTO")
*/
protected $id;
/**
* @ORM\OneToMany(targetEntity="Billion\UserBundle\Entity\Friends", mappedBy="myFriends")
**/
private $myFriends;
/**
* Get id
*
* @return integer
*/
public function getId()
{
return $this->id;
}
/**
* Constructor
*/
public function __construct()
{
$this->myFriends = new \Doctrine\Common\Collections\ArrayCollection();
}
/**
* Add myFriends
*
* @param \Billion\UserBundle\Entity\Friends $myFriends
* @return Users
*/
public function addMyFriend(\Billion\UserBundle\Entity\Friends $myFriends)
{
$this->myFriends[] = $myFriends;
return $this;
}
/**
* Remove myFriends
*
* @param \Billion\UserBundle\Entity\Friends $myFriends
*/
public function removeMyFriend(\Billion\UserBundle\Entity\Friends $myFriends)
{
$this->myFriends->removeElement($myFriends);
}
/**
* Get myFriends
*
* @return \Doctrine\Common\Collections\Collection
*/
public function getMyFriends()
{
return $this->myFriends;
}
}
以下是我对用户的排除政策:
Billion\AlbumBundle\Entity\Album:
exclusion_policy: ALL
properties:
name:
expose: true
longitude:
expose: true
latitude:
expose: true
visibility:
expose: true
medias:
expose: true
owner:
expose: true
感谢您的帮助!

我建议使用JMSSerializerBundle&#39; exclusion strategy for creating different views。这样,您可以根据视图对对象进行不同的序列化。因此,在您的情况下,您可以创建一个序列化相册的视图,该视图仅在用户对象时显示用户名。然后,您可以使用另一个视图来序列化完整的用户对象,以便在显示所有属性时使用。
以下是一个示例,我使用的是注释,但您也可以使用yaml配置。我也没有使用过FOSUserBundle,所以我的课程有点不同,但是它得到了重点。
class User implements AdvancedUserInterface
{
/**
* @Groups({"user"})
*
* @ORM\Column(name="user_id", type="integer", nullable=false)
* @ORM\Id
* @ORM\GeneratedValue(strategy="SEQUENCE")
*/
private $userId;
/**
* @Groups({"user", "album"})
* @ORM\Column(name="username", type="string", nullable=true)
*/
private $username;
/**
* @Exclude
* @ORM\Column(name="password", type="string", nullable=true)
*/
private $password;
// .......
}
在你的专辑课上,有:
class Album
{
/**
* @var integer
* @Groups({"album"})
* @ORM\Column(name="id", type="integer")
* @ORM\Id
* @ORM\GeneratedValue(strategy="AUTO")
*/
private $id;
/**
* @var string
* @Groups({"album"})
* @ORM\Column(name="name", type="string", length=255)
*/
private $name;
// ......
}
以下是如何在控制器中使用它的示例(FOSRestBundle)
/**
* Get currently logged in user
*/
public function getCurrentuserAction(){
$loggedInUser = $this->get('security.context')->getToken()->getUser();
$view = $this->view($loggedInUser , 200);
$view->setSerializationContext(
SerializationContext::create()->setGroups(array('user'))
);
return $this->handleView($view);
}
/**
* Get album
*/
public function getCurrentuserAction(){
$album = // get your album object
$view = $this->view($album , 200);
// set the group to only include the 'album' properties (including the 'album' marked username in the user object)
$view->setSerializationContext(
SerializationContext::create()->setGroups(array('album'))
);
return $this->handleView($view);
}
此方法非常灵活,您可以根据需要创建任意数量的组。
