我已经定义了两个数据库实体
项目:
use Doctrine\ORM\Mapping as ORM;
use \Kdyby\Doctrine\Entities\MagicAccessors;
/**
* @ORM\Entity
*/
class Project extends \Kdyby\Doctrine\Entities\BaseEntity
{
/**
* @ORM\Id
* @ORM\Column(type="integer")
* @ORM\GeneratedValue
*/
public $id;
/**
* @ORM\Column(type="string")
*/
public $title;
/**
* @ORM\Column(type="text")
* @var string
*/
public $description;
/**
* @ORM\Column(type="datetime", nullable=true)
* @var DateTime
*/
public $created;
/**
* @ORM\Column(type="boolean")
* @var string
*/
public $public;
/**
* @ORM\Column(type="blob")
* @var string
*/
public $thumbnail;
public function __construct()
{
$this->created = new \DateTime();
$this->public = 0;
}
}
和人物:
use Doctrine\ORM\Mapping as ORM;
use \Kdyby\Doctrine\Entities\MagicAccessors;
/**
* @ORM\Entity
*/
class Personage extends \Kdyby\Doctrine\Entities\BaseEntity
{
/**
* @ORM\Id
* @ORM\Column(type="integer")
* @ORM\GeneratedValue
*/
public $id;
/**
* @ORM\Column(type="string")
*/
public $name;
/**
* @ORM\Column(type="text", nullable=true)
* @var string
*/
public $shortDescription;
/**
* @ORM\Column(type="text", nullable=true)
* @var string
*/
public $playerDescription;
/**
* @ORM\Column(type="datetime")
* @var DateTime
*/
public $created;
/**
* @ORM\Column(type="integer")
* @var string
*/
public $creator;
/**
* @ORM\Column(type="boolean", options={"default" = false})
* @var boolean
*/
public $inGraph;
/**
* @ORM\Column(type="boolean", nullable=false, options={"default" = 0})
* @var boolean
*/
public $deleted;
/**
* @ORM\ManyToOne(targetEntity="Project", cascade={"persist", "remove"})
* @ORM\JoinColumn(name="project", referencedColumnName="id", onDelete="CASCADE")
* @var string
*/
public $project_id;
public function __construct()
{
$this->deleted = 0;
$this->inGraph = 0;
}
}
每个Personage实体都属于某个项目。但每当我尝试以这种方式删除Personage时:
public function removeChar($id)
{
$a = $this->EntityManager->find('App\Personage', $id);
if($a->deleted)
{
$this->EntityManager->remove($a);
$this->EntityManager->flush();
}
}
或使用dql。它也会删除整个项目行。我想要的是每当项目被删除时,它会删除所有相应的字符,但不是其他方式。
我试图删除
cascade={"persist", "remove"}
部分来自Project实体声明(并通过控制台更新数据库),但它说所有内容都是同步的,什么也没做。所以我删除了整个数据库并在没有cascade={"persist", "remove"}
的情况下构建它,但问题没有解决。
答案 0 :(得分:0)
删除onDelete =" CASCADE"来自
@ORM\JoinColumn(name="project", referencedColumnName="id", onDelete="CASCADE")
并添加
@ORM\OneToMany(targetEntity="Personage", mappedBy="project_id",cascade={"remove"})
private $personages;
在项目实体中。
