在querybuilder中不使用count的原则分页器

Question

每个磁盘(d)都有一个相关的注释(n)集合。我的querybuilder是根据与Note相关的数量来获取每个Disque。

这是课堂上的一个高峰

class Disque
{
    ...

    /**
    * @ORM\ManyToMany(targetEntity="Note", cascade={"persist"})
    */
    private $notes;

    ...

}

class Note
{
    ...

    /**
     * @ORM\ManyToOne(targetEntity="NoteValeur", cascade={"persist"})
     * @ORM\JoinColumn(nullable=true)
     */
    private $noteValeur;

    ...
}

class NoteValeur
{
    ...
    /**
     * @Gedmo\Slug(fields={"titre"})
     * @ORM\Column(name="slug", unique=true, length=32)
     */
    private $slug;
}

我使用来获取结果，使用计数来设置阈值。

<?php

...

class DisqueRepository extends \Doctrine\ORM\EntityRepository
{
    public function getDisquesByNotesAndAllInfo($slug, $seuil, $page, $nbPerPage)
    {
        $q = $this->createQueryBuilder('d');
        $q
                ->select('d as infosDisque')
                ->leftJoin('d.pochettes', 'p')
                ->addSelect('p')
                ->leftJoin('d.groupes','g')
                ->addSelect('g')
                ->leftJoin('d.labelDisque', 'l')
                ->addSelect('l')
                ->leftJoin('d.chroniques','c')
                ->addSelect('c')
                ->leftJoin('d.notes', 'n')
                ->addSelect('n')
                ->innerJoin('n.noteValeur','nv')
                ->addSelect('nv')
                ->groupBy('d')
                ->addSelect('COUNT(d) as NbNotes')
                ->where('nv.slug LIKE :slug')
                ->setParameter('slug', $slug)
                ->having($q->expr()->gte('NbNotes',':seuil'))
                ->setParameter('seuil', $seuil)
                ->setFirstResult( ($page-1) * $nbPerPage)
                ->setMaxResults($nbPerPage)
                ->orderBy('d.dateSortieDisque', 'desc')
        ;

        return new Paginator($q, true);

    }
}

结果集非常好。问题是，当我更改$page值时，SQL中的偏移量不会增加。不管发生什么我都能得到相同的结果。

Symfony分析器提供了以下可执行查询

SELECT DISTINCT id_44 
FROM (
    SELECT 
        COUNT(s0_.id) AS sclr_0, s0_.id AS id_1, s0_.titre AS titre_2, s0_.datesortiedisque AS datesortiedisque_3, s0_.nombreDisque AS nombreDisque_4, s0_.remarque AS remarque_5, s0_.tracklist AS tracklist_6, s0_.lineup AS lineup_7, s0_.slug AS slug_8, s0_.coderef AS coderef_9,

    HAVING 
        sclr_0 >= 2
) dctrn_result 
ORDER BY datesortiedisque_3 DESC LIMIT 10 OFFSET 10 

无论传递给$q->setFirstResult()方法，我似乎都无法更改此查询中的偏移量。

有人有线索吗？

Answer 1

嗯，你猜怎么着，我在我的控制器中使用了一个调试值，我已经忘记了它：

$disques = $dr->getDisquesByNotesAndAllInfo($slug, $seuil, 2, $nbPerPage);

所有的工作都很好，因为我改变了这个混乱的"2“值。真对不起。感谢你们两位的帮助！
