我有一个问题，我一直在思考，并且不知道如何解决......你能指导我正确的方向，还是给我任何建议来解决它？
我有一个咨询表，每行有很多消息。我想用一定的标准来检索所有的咨询，然后返回按标签排序的列表，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：

namespace Common\Entity;
use Doctrine\ORM\Mapping as ORM;
/**

我会为此作业写一个entity repository，而不是基础DQL的内置findBy()方法。
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]);
由于您在两个表中都有大量记录，因此需要使用paginator并将其传递给视图层。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。
希望它有所帮助。

虽然希望有一个正确的方法来解决这个问题（在我的数据库中对它进行排序），但这里有一个黑客可以对它进行排序：
/**
* @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;
}
按我的消息Date排序，但我也可以按ID排序......
