我在控制器中有这个：
$em = $this->getDoctrine()->getManager();
$repository = $this->getDoctrine()->getRepository('ProjectFrontendBundle:Item');
$item = $repository->find(3);
$item->setPosition('10');
var_dump($item->getPosition()); exit(); //this returns 10
$em->persist($item);
$em->flush();
var_dump($item->getPosition()); exit();//this returns 5
return $this->render('ProjectBackendBundle:Default:prueba.html.twig');
问题：位置（10）的新值未保存在数据库（MySQL）中。
我得到这个日志：
1207 Query SELECT t0.id AS id1, t0.position AS position2, t0.image_name AS image_name3, t0.updatedAt AS updatedAt4, t0.slug AS slug5, t0.nombre AS nombre6, t0.activado AS activado7, t0.parent_id AS parent_id8 FROM Item t0 WHERE t0.id = 3
1207 Query SELECT MAX(i0_.position) AS sclr0 FROM Item i0_
1207 Query START TRANSACTION
1207 Query UPDATE Item SET position = 5 WHERE id = 3
1207 Query commit
1207 Quit
这是我的实体Item：

我没有在apache或symfony日志中收到错误。
答案 0 :(得分：0)
问题是因为Doctrine Sortable行为。我有4个元素，当我尝试给出一个高于5（6,7,8,9等）的位置时，它将它转换为5，因为我的上一个位置是4。
