Doctrine / Symfony - 实体之间的冲突。试图建立关系。我收到一个错误

我的实体总是遇到异常。我试着和他们一起玩。我检查了谷歌哪个关系最适合我的实体...但我找不到最好的配置。

我正在创建一个网站,您可以在其中创建一个简单的帖子,并在其中创建一些专辑。

3个实体:专辑/邮政/图片

在相册中我有一个图片数组,我在Poste也有一个图片数组。

用户可以拥有多个相册。 在Album Entity中,我确实让用户保留了一个参考。

/**
* Album
*
* @ORM\Table(name="album")
* @ORM\Entity(repositoryClass="Moodress\Bundle\AlbumBundle\Entity\AlbumRepository")
*/

class Album
{
/**
 * @var integer
 *
 * @ORM\Column(name="id", type="integer")
 * @ORM\Id
 * @ORM\GeneratedValue(strategy="AUTO")
 */
private $id;

/** 
 ** @ORM\ManyToOne(targetEntity="Moodress\Bundle\UserBundle\Entity\User")
 ** @ORM\JoinColumn(nullable=false) 
 */
private $user;

/**
 * @var string
 *
 * @ORM\Column(name="name", type="string", length=255)
 */
private $name;

/**
 * @var \DateTime
 *
 * @ORM\Column(name="creationDate", type="datetime")
 */
private $creationDate;

/**
 * @var \DateTime
 *
 * @ORM\Column(name="modificationDate", type="datetime")
 */
private $modificationDate;

 /**
 * @ORM\OneToMany(targetEntity="Moodress\Bundle\AlbumBundle\Entity\Picture", cascade={"persist"}, mappedBy="album")
 */
 private $pictures;

/**
 * Constructor
 */
public function __construct()
{
    $this->creationDate = new \Datetime();
    $this->modificationDate = new \Datetime();
}
 // Get and set
}

当用户在网站上订阅时,我创建了一个名为Upload的默认相册,我希望将其保留在用户类中。

这就是我试图做的事情:

/**
* User
*    
* @ORM\Entity
* @ORM\Table(name="user")
*/
class User extends BaseUser  
{
/**
* @ORM\Id
* @ORM\Column(type="integer")
* @ORM\GeneratedValue(strategy="AUTO")
*/
 protected $id;

/**
 * @ORM\OneToOne(targetEntity="Moodress\Bundle\AlbumBundle\Entity\Album", cascade={"persist"})
 */
 protected $albumUpload;

 // Get and set
}

我的Poste实体带有图片数组:

/**
 * Poste
 *
 * @ORM\Table(name="poste")
 * @ORM\Entity(repositoryClass="Moodress\Bundle\PosteBundle\Entity\PosteRepository")
 */
class Poste
{
    /**
     * @var integer
     *
     * @ORM\Column(name="id", type="integer")
     * @ORM\Id
     * @ORM\GeneratedValue(strategy="AUTO")
     */
    private $id;

    /**
     * @ORM\ManyToOne(targetEntity="Moodress\Bundle\UserBundle\Entity\User")
     * @ORM\JoinColumn(nullable=true)
     */
    private $user;

    /**
     * @var string
     *
     * @ORM\Column(name="description", type="text")
     */
    private $description;

     /**
     * @ORM\OneToMany(targetEntity="Moodress\Bundle\AlbumBundle\Entity\Picture", cascade={"persist"}, mappedBy="poste")
     */
     private $pictures;

     // Getters and setters
}

我的图片实体:

/**
 * Picture
 *
 * @ORM\Table(name="picture")
 * @ORM\Entity(repositoryClass="Moodress\Bundle\AlbumBundle\Entity\PictureRepository")
 */
class Picture
{
    /**
     * @var integer
     *
     * @ORM\Column(name="id", type="integer")
     * @ORM\Id
     * @ORM\GeneratedValue(strategy="AUTO")
     */
    private $id;

    /** 
     ** @ORM\ManyToOne(targetEntity="Moodress\Bundle\UserBundle\Entity\User")
     ** @ORM\JoinColumn(nullable=false) 
     */
    private $user;

     /**
     * @Assert\File(maxSize="6000000")
     */
    private $file;

    /**
     * @var string
     *
     * @ORM\Column(name="name", type="string", length=255)
     */
    private $name;

    /**
     * @var string
     *
     * @ORM\Column(name="path", type="string", length=255)
     */
    private $path;

    // Getters and setters
}

我有这个错误:Undefined index: album in /Users/Sandro/sites/moodress-website/Symfony/vendor/doctrine/orm/lib/Doctrine/ORM/Persisters/BasicEntityPersister.php line 1608. 当我序列化任何具有用户对象的实体时,会立即出现此错误...

在日志中:

at ErrorHandler->handle('8', 'Undefined index: album', '/Users/Sandro/sites/moodress-website/Symfony/vendor/doctrine/orm/lib/Doctrine/ORM/Persisters/BasicEntityPersister.php', 
'1608', array('assoc' => array('fieldName' => 'pictures', 'mappedBy' => 'album', 
'targetEntity' => 'Moodress\Bundle\AlbumBundle\Entity\Picture', 
'cascade' => array('persist'), 'orphanRemoval' => false, 'fetch' => '2', 
'type' => '4', 'inversedBy' => null, 'isOwningSide' => false, 'sourceEntity' => 'Moodress\Bundle\AlbumBundle\Entity\Album', 'isCascadeRemove' => false, 
'isCascadePersist' => true, 'isCascadeRefresh' => false, 'isCascadeMerge' => false, 
'isCascadeDetach' => false), 'sourceEntity' => object(Album), 'offset' => null, 
'limit' => null, 'criteria' => array())) in /Users/Sandro/sites/moodress-website/Symfony/vendor/doctrine/orm/lib/Doctrine/ORM/Persisters/BasicEntityPersister.php line 1608

我不知道我的实体有什么问题。有帮助吗?

1 个答案:

答案 0 :(得分:1)

错误:

'Undefined index: album'

来自Album类中的此注释。

/**
 * @ORM\OneToMany(
 *      targetEntity="Moodress\Bundle\AlbumBundle\Entity\Picture",
 *      cascade={"persist"}, 
 *      mappedBy="album"
 *  )
 */

您已将mappedBy设置为album,但$album类中没有Picture属性。

将其添加到Picture课程并清除缓存。

/**
 * @ORM\ManyToOne(
 *      targetEntity="Moodress\Bundle\AlbumBundle\Entity\Album",
 *      inversedBy="pictures"
 *  )
 */
protected $album;
