我正在使用Symfony 3.1 Doctrine GEDMO扩展(通过StofDoctrineExtensionsBundle).我已将我的实体设置为具有可排序行为:
<?PHP
namespace AppBundle\Entity\Manual;
use AppBundle\Entity\Identifier;
use Doctrine\ORM\Mapping as ORM;
use Symfony\Component\Validator\Constraints as Assert;
use Gedmo\Mapping\Annotation as Gedmo;
/**
* @ORM\Table(name="manual_pages")

*/
class Manual
{
use Identifier;
/**
* @ORM\Column(type="string")

private $title;

private $content;

* @ORM\OrderBy({"position"="ASC"})
*/
private $images;
/**
* @Gedmo\SortablePosition
* @ORM\Column(type="integer",nullable=false)
*/
private $position;
/**
* @return mixed
*/
public function getPosition()
{
return $this->position;
}
/**
* @param mixed $position
*/
public function setPosition($position)
{
$this->position = $position;
}
/**
* @return mixed
*/
public function getTitle()
{
return $this->title;
}
/**
* @param mixed $title
*/
public function setTitle($title)
{
$this->title = $title;
}
/**

*/
public function getImages()
{
return $this->images;
}
/**
* @param ManualImage[] $images

public function setImages($images)
{
$this->images = $images;
}
/**

public function getContent()
{
return $this->content;

public function setContent($content)
{
$this->content = $content;
}
}
当我继续改变位置时,排序行为表现良好:
$entity->setPosition($entity->getPosition() + 1);
// or
$entity->setPosition($entity->getPosition() - 1);
但是当我实现JS拖放以改变位置时,整个事情变得奇怪.例如,有这个表:
id | position
1 | 0
2 | 1
3 | 2
4 | 3
5 | 4
6 | 5
当我为id为6的行做时:
$newPosition = $entity->getPosition() - 5; // = 0
$entity->setPosition($newPosition);
表格改为:
id | position
1 | 2
2 | 3
3 | 4
4 | 5
5 | 5
6 | 0
位置1没有任何东西,但位置5被占用两次.有任何想法吗?
我们很久以前就发现了这个bug.在我们的情况下,当您同时设置多个位置/刷新时出现问题.我们最终使用了没有gedmo扩展名的javascript的完整排序顺序,因为单次刷新太贵了.
