Symfony2:缺少分配的ID [英] Symfony2 : missing an assigned ID

问题描述

我有一个Place和一个Placetype实体.我的位置实体的id属性设置为AUTO:

I have a Place and a Placetype entity. My Place entity have his id attribute set to AUTO:

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

但是当我要保留一个对象时，出现以下错误:

But when I want to persist an object, I got the following error :

blabla \ Entity \ Place类型的实体缺少分配的ID.这该实体的标识符生成策略需要ID字段在调用EntityManager#persist()之前填充.如果你想自动生成的标识符，而您需要调整元数据映射.

Entity of type blabla\Entity\Place is missing an assigned ID. The identifier generation strategy for this entity requires the ID field to be populated before EntityManager#persist() is called. If you want automatically generated identifiers instead you need to adjust the metadata mapping accordingly.

您知道如何解决此问题吗?

Do you know how to fix this?

感谢您的帮助

推荐答案

它可以通过替换以下内容来实现:

It works by replacing this :

/**
 * @var integer $uid
 *
 * @ORM\Column(name="id", type="integer", nullable=false)
 * @ORM\Id
 * @ORM\GeneratedValue(strategy="AUTO")
 */
private $id;

对此:

/**
 * @var integer $uid
 *
 * @ORM\Column(name="id", type="integer", nullable=false)
 * @ORM\Id
 */
private $id;
