我只是想知道(id = 1)的学生通过了多少测试。 在我的数据库中,id = 1的学生已通过一次测试。
DB和下面链接中的运行结果:
TestRepository中的GetAvg()方法做了学生1已经通过的测试计数。
NoteMatiereController:
public function showMarksByStudentAction($idMat)
{ $iduser=$this->getUser()->getId();
$em = $this->getDoctrine()->getManager();
$notes = $em->getRepository("AcmeMyBundle:NoteMatiere")
->showMarksByStudent($iduser, $idMat);
$moys = $em->getRepository("AcmeMyBundle:Test")
->GetAVG();
print_r ($moys);
return($this->render("AcmeMyBundle:NoteMatiere:listNotes.html.twig", array("notes" => $notes,"moys"=>$moys)));
}
NoteMatiereRepository:
public function showMarksByStudent($student_id,$mat_id)
{
$query=$this->getEntityManager()
->createQuery("SELECT n from AcmeMyBundle:Etudiant e ,AcmeMyBundle:NoteMatiere n,AcmeMyBundle:Test t,AcmeMyBundle:MatiereProf m WHERE n.idEt=?1 and t.idTest = n.idTest and t.idMatProf = m.id and m.idMat=?2")
->setParameter(1, $student_id)
->setParameter(2, $mat_id);
return $query->getResult();
}
TestRepository:
public function GetAVG()
{
$qb = $this->createQueryBuilder('m');
$qb->select('n.idEt,t.idTest,t.coefTest,count(t.coefTest) as ts')
->from('AcmeMyBundle:Test', 't')
->from('AcmeMyBundle:NoteMatiere', 'n')
->where('n.idEt=1 and t.idTest = n.idTest');
// -> and where(t.idTest = n.idTest) ; is the same
return $qb->getQuery()->getResult();
}
不添加条件t.idTest = n.idTest计数结果为16!
ListNote.html.twig:它将帮助您了解视图的工作原理。
<table border=1>
<tr>
<!-- <th>Description</th>
<th>Note</th>
!-->
<th>Liste des Tests</th>
<th>Note</th>
</tr>
{% for note in notes %}
<tr>
<td>{{ note.idTest }}</td>
<td>{{ note.note }}</td>
</tr>
{%endfor%}
</table>
<table>
{% for moy in moys %}
<td>id Test ==>{{ moy.idTest }}</td>
<td>Coef Test ==>{{ moy.coefTest }}</td>
<td>Count Coef Test ==>{{ moy.ts }}</td>
{%endfor%}
</table>

我的陈述是如此之久,但经过长时间的测试,问题就在那里,我真的很累。感谢帮助!
答案 0 :(得分:0)
试试这个:
public function GetAVG()
{
$qb = $this->createQueryBuilder('test');
$qb->select('nota.idEt,test.idTest,test.coefTest,count(test.coefTest) as ts')
->join('test.noteMaterie', 'nota', Join::WITH. 'test.idTest=nota.idTest') //You can skip the 4 param here if its the regular realtionship parameter
->where('nota.idEt = 1');
return $qb->getQuery()->getResult();
}
请改变关系,因为它们在您的情况下命名!
