查找所有 post 并按 post 中的最新消息排序。 Doctrine2 和 ZF2

Question

我有一个问题我想了很久，不知道怎么解决...你能指导我正确的方向或者给我一些解决问题的建议吗？

我有一个咨询table，每一行都有很多消息。我想检索符合特定条件的所有咨询，然后 return 按标签排序的列表，以及 OneToMany 关系中的最后一项...

这是我现在的代码：

public function indexAction()
{
    $em = $this->getEntityManager();
    /** @var EntityRepository $repo */
    $repo = $em->getRepository('Common\Entity\Konsultasjon');
    $meldinger = $repo->findBy([
            'kundeid' => '1',
            'state' => '1',
            'skjult' => '0'
            ],[
                'tag' => 'ASC',
            ]
        );


    return new ViewModel(['meldinger' => $meldinger]);
}

这是我的 Konsultasjon 实体：

Answer 1

虽然希望有一个正确的方法来解决这个问题（在我的数据库中对其进行排序），但这里有一个对其进行排序的技巧：

/**
 * @param \Common\Entity\Meldinger[] $meldinger
 * @return \Common\Entity\Meldinger[]
 */
public function sortMeldinger(array $meldinger)
{
    $sort = array();
    /**
     * @var \Common\Entity\Konsultasjon $v
     */
    foreach ($meldinger as $k => $v) {
        $sort['tag'][$k] = $v->getTag();
        /** @var \Common\Entity\Meldinger $last */
        $last = $v->getMeldinger()->last();
        $sort['dato'][$k] = $last->getDato(); //end($v['meldinger'])['dato'];
    }
    array_multisort($sort['tag'], SORT_ASC, $sort['dato'], SORT_ASC, $meldinger);

    return $meldinger;
}

这是按我的消息日期排序的，但我也可以按 ID 排序...

Answer 2

而不是基础 entity repository, I would write a DQL 的内置 findBy() 方法来完成这样的工作。

例如：

$em = $this->getEntityManager();
$dql = 'SELECT K, M
        FROM Common\Entity\Konsultasjon K
        LEFT JOIN Common\Entity\Meldinger M
        WHERE K.kundeid = :kid AND
              K.state = :st AND
              K.skjult = :skj
        ORDER BY K.tag DESC,
                 M.dato DESC';

$query = $em->createQuery($dql);
$query->setParameter('kid', 1)
      ->setParameter('st', 0)
      ->setParameter('skj', 0);

 $pagination = new \Doctrine\ORM\Tools\Pagination\Paginator($query);
 $adapter    = new \DoctrineORMModule\Paginator\Adapter\DoctrinePaginator($pagination);
 $paginator  = new \Zend\Paginator\Paginator($adapter);

 $paginator->setCurrentPageNumber(1)
           ->setDefaultItemCountPerPage(50);

 return new ViewModel(['paginator' => $paginator]);

在这里使用分页器并将其传递到视图层是一项要求，因为您在两个表中都有很多记录。将此逻辑移动到自定义存储库（例如 KonsultasjonRepository）也是一种很好的做法。

希望对您有所帮助。
