php - Doctrine DQL 子查询给出零结果

Question

我在 Mysql 服务器上有三个相关实体:Group、GroupDefault、GroupDefaultTranslation。

• Group 实体存储用户的组。
• GroupDefault 实体定义任何用户的默认组。
• GroupDefaultTranslation 实体存储默认组的翻译。

实体之间的关系是类型: - Group 和 GroupDefault 之间的 ManyToOne - OneToManu ent GroupsDefault 和 GroupDefaultTranslation

我的目标是显示用户的组列表，并在其语言参数中显示相应的翻译。

这是我的 QueryBuilder，生成了 DQL 查询:

public function findByOwnerWithLanguage($languageCode, $ownerId)
{
        $qb = $this->createQueryBuilder('g')
            ->select('g.name')
            ->addSelect('gdt.content AS name')
            ->join('g.parent', 'gd')
            ->join('gd.translations', 'gdt')
            ->where('g.owner = :owner');

            //création de l'expression AND
            $orModule = $qb->expr()->andX();
            $orModule->add($qb->expr()->eq('g.parent', '0'));
            $orModule->add($qb->expr()->eq('gdt.locale', ':language'));
            $orModule->add($qb->expr()->eq('g.owner', ':owner'));


         //Ajout de l'expression à la requête
         $qb->orWhere($orModule)
            ->setParameter('language', $languageCode, \PDO::PARAM_STR)
            ->setParameter('owner', $ownerId)
            ->orderBy('g.isMyLightbox', 'DESC')
            ->getQuery()
            ->getResult();
    return $qb;

    // DQL Query :

    // SELECT g.name, gdt.content AS name
    // FROM Horyou\Bundle\CoreBundle\Entity\Group g
    // INNER JOIN g.parent gd
    // INNER JOIN gd.translations gdt
    // WHERE g.owner = :owner
    // OR (g.parent = 0 AND gdt.locale = :language AND g.owner = :owner)
    // ORDER BY g.isMyLightbox DESC

}

这是对象 var_dump 的输出:

  public '__CLASS__' => string 'Doctrine\ORM\QueryBuilder' (length=25)

我的问题是结果为零。 有人看到我的 QueryBuilder 中的错误是什么吗？

Answer 1

实际上这不是结果 - 它只是查询构建器对象的转储。我认为你必须做这样的事情:

...
$qb->orWhere($orModule)
        ->setParameter('language', $languageCode, \PDO::PARAM_STR)
        ->setParameter('owner', $ownerId)
        ->orderBy('g.isMyLightbox', 'DESC');
$result = $qb->getQuery()->getResult();

return $result;
