【问题描述】:
我想展示我拥有的每款不同游戏的最佳 5 分。所以我做了这个功能:
public function records (){
$em = $this->getDoctrine()->getManager();
$games = $em->getRepository(Game::class)->findAll();
foreach($games as $g){
$records = new ArrayCollection;
$records = $em->getRepository(Game::class)->findAllRecords($g->getId());
}
return $this->render('game/records.html.twig', [
'games' => $games,
'records' => $records,
]);
}
这里是存储库功能:
public function findAllRecords($id){
$qb = $this->createQueryBuilder('g');
$qb->select('g.name')
->innerJoin('g.Parties', 'p')
->innerJoin('p.playeds', 'y')
->innerJoin('y.joueur', 'j')
->addSelect('y.score')
->addSelect('j.nom, j.prenom')
->where('g.id = :id')
->setParameter('id', $id)
->orderBy('y.score', 'DESC')
->setMaxResults('5');
var_dump($qb->getDQL());
$query = $qb->getQuery();
return $query->getResult();
}
最后是视图:
{% for g in games %}
{{ g.name }}
<table class="table">
<tbody>
<tr>
<th>score</th>
</tr>
{% for r in records %}
<tr>
<td>{{ r.score }}</td>
</tr>
{% endfor %}
</tbody>
</table>
{% endfor %}
它并不完全有效,因为我只是从最后一个游戏 ID 中获取数据。如何显示每场比赛的数据?
