我在实习期间将Symfony 1.x的网站更新为Symfony 2.1，而且我对Doctrine的注释有一些问题。顺便说一下，我是Symfony2的新手。
我遇到了这种类型的例外：
在渲染模板期间抛出了异常 （“[语义错误]注释”@Doctrine \ ORM \ Mapping \ OrderBy“in 属性IHQS \ NuitBlancheBundle \ Entity \ SC2Profile :: $ games没有 存在，或无法自动加载。“）in “/var/www/sites/nuitblanche1/src/IHQS/NuitBlancheBundle/Resources/views/News/archives.html.twig”。
我的代码是：
<?php
namespace IHQS\NuitBlancheBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
use Symfony\Component\Validator\Constraints as Assert;

我也遇到了与自动加载或不存在的Constraint / Regex相同的问题。虽然我的所有学说捆绑都在工作。 我的问题有点简单：我做错了什么？ （我知道这不是一个非常特殊的人！）
答案 0 :(得分：1)
问题与@ORM\OrderBy({"id" = "DESC"})注释无关。这看起来是正确的，你已经包含了use Doctrine\ORM\Mapping as ORM;。
问题似乎与您的SC2Profile实体和GamePlayer实体之间的关系有关。这两个实体都在IHQS\NuitBlancheBundle\Entity命名空间中吗？
您可以尝试更新关系以使用完全限定的类名。
/**
* @ORM\OneToMany(targetEntity="\IHQS\NuitBlancheBundle\Entity\GamePlayer", mappedBy="player")
* @ORM\OrderBy({"id" = "DESC"})
*/
protected $games;
最后，请确保在ManyToOne实体中设置了相反的关系（GamePlayer）。
/**
* @ORM\ManyToOne(targetEntity="SC2Profile", inversedBy="games")
* @ORM\JoinColumn(name="id", referencedColumnName="referenced_id")
*/
protected $player;
