Symfony/Doctrine:类不是有效的实体或映射的超类 [英] Symfony/Doctrine: Class is not a valid entity or mapped super class

问题描述

我收到Class PriceOrQuality\POQBundle\Entity\Tag 不是有效实体或映射的超类错误.我已经检查了类似问题的所有答案，但我似乎无法理解问题.

I'm getting the "Class PriceOrQuality\POQBundle\Entity\Tag is not a valid entity or mapped super class error. I've have checked all the answers to similar questions, but I cannot seem to grasp the problem.

错误是由我的存储库类引发的

The error is thrown by my Repository Class

<?php

namespace PriceOrQuality\POQBundle\Entity\Repository;

use Doctrine\ORM\EntityRepository as ER;
use PriceOrQuality\POQBundle\Entity\Tag;
use Doctrine\ORM\EntityManager;

/**
 * EntityTagsRepository
 *
 */
class EntityTagsRepository extends ER
{
    public function getTagsForTagCloud($entity_ids = null, $tag_id = null) {

        $em = $this->getEntityManager();

        $qb = $em->createQueryBuilder();
        $qb->select(array('IDENTITY(et.tag) as id, COUNT(et.tag) as tag_id_count, LOWER(t.tag) as tag'));
        $qb->from('PriceOrQuality\POQBundle\Entity\EntityTag', 'et');
        $qb->leftjoin('PriceOrQuality\POQBundle\Entity\Tag','t', 'WITH', 'et.tag = t.id');
        $qb->groupBy('et.tag');
        $qb->addOrderBy('tag_id_count','DESC');
        $qb->setMaxResults(20);      
        return $qb->getQuery()
                ->getResult();
    }
}

在这个文件(Tag.php)中定义了Tag类(仅限定义):

The Tag class is defined in this file (Tag.php) (definition only):

<?php

namespace PriceOrQuality\POQBundle\Entity;

// src/PriceOrQuality/POQBundle/Entity/Tag.php

use Doctrine\ORM\Mapping as ORM;
use Doctrine\Common\Collections\ArrayCollection;
use PriceOrQuality\POQBundle\Entity\EntityTag;
use PriceOrQuality\POQBundle\Entity\User;
use JMS\SerializerBundle\Serializer\Serializer;

/**
 * @ORM\Entity(repositoryClass="PriceOrQuality\POQBundle\Entity\Repository\TagsRepository")
 * @ORM\Table(name="tags")
 * @ORM\HasLifecycleCallbacks 
 */

有没有聪明人知道从哪里开始调试?

Does any of you smart guys have any idea on where to start with the debugging?

推荐答案

发现问题.

我在元定义之后和类定义之前有一个//@todo.显然，这搞砸了映射，因为它没有在学说中映射.

I had a //@todo after the meta definition and before the class definition. Apparently that screwed up the mapping, as it was not mapped in doctrine.

移动//@todo 并重新运行映射解决了问题.

Moving the //@todo and rerunning the mapping fixed the problem.

对于发现此问题具有类似问题的人，请尝试运行:

For whomever finds this question with similar problems try running:

php app/console doctrine:mapping:info

它会告诉你你在学说中的映射结构是否有问题

It will show you if you have problems in the mapping structure in doctrine

感谢您的时间.
