Symfony2 - Count row / Joined Tables - symfony

Question

I'm a begginer in Symfony2...
I have a table "TUTORIEL" and an other table 'Groupe_de_categories' linked by 'id_groupe_categorie'
TABLE Tutoriels :
TABLE Groupe_de_categories
I need to count for each "titre_categorie_nv1" (here in my example 'Maison', 'Art&Loisir', 'Enseignement'...) how many "TUTORIEL" I have where "tutoriel_controle" = 'no'
Before to use Synfony2, I hade this code in PHP (works nice):
<?php
$query_nb_cat = "SELECT CATEGORIE, COUNT(*)
FROM Tutoriels
INNER JOIN Groupe_de_categories
ON TUTORIEL.id_groupe_categorie = Groupe_de_categories.id_groupe_categorie
WHERE tutoriel_controle='no'
GROUP BY CATEGORIE_TITLE";
$nb_cat = mysqli_query($BDD_connect, $query_nb_cat)or die(log_mysql($query_nb_cat));
$row_nb_cat = mysqli_fetch_assoc($nb_cat);
do {
$tableau_nb_cat[]=array(
'titre_cat_nv1'=>$row_nb_cat['titre_categorie_nv1'],
'compte_cat_nv1'=>$row_nb_cat['COUNT(*)'],
);
} while ($row_nb_cat = mysqli_fetch_assoc($nb_cat));
$val_cat=array(
'valeur_retour'=>$tableau_nb_cat
);
mysqli_free_result($nb_cat);
mysqli_close($BDD_connect);
?>
The result was something like that :
Maison => 3
Art&Loisir => 9
Enseignement => 14
...
How can I do this with Symfony2 ?
Here is my ORM :

Answer 1

You can do it by using createQueryBuilder in your repository, or you can use your current query as NativeQuery
Here is a sample (I assume the name of your entities are Tutoriels and GroupeDeCategories)
$em = $this->getDoctrine()->getManager();
$query = $em->getRepository('YourBundle:Tutoriels')
->createQueryBuilder('T')
->join('T.idGroupeCategorie', 'GC')
-->select('COUNT(GC.titreCategorieNv1) AS CT1')
->where("T.tutorielControle = 'no'")
->groupBy('GC.titreCategorieNv1')
->getQuery();
$result = $query->getScalarResult(); //This will return an array of the counts
In your entity I could not find CATEGORIE_TITLE to use in GroupBy and CATEGORIE to add in the selection; so I grouped them by titreCategorieNv1. You can add more fields for your select.
Maybe this link helps you more Symfony CreateQueryBuilder

Answer 2

I did that :
public function updateAction($type_update)
{
$request = Request::createFromGlobals();
$result = $request->isXmlHttpRequest();
if ($result === true) {
switch ($type_update) {
case "compteur_menu":
$em = $this->getDoctrine()->getManager();
$result = $em->createQuery("
SELECT TC.titreCategorieNv1, COUNT(TC.titreCategorieNv1) AS num
FROM Video2LearnBddBundle:Tutoriels T
INNER JOIN T.idGroupeCategorie GC
INNER JOIN GC.titreCategorieNv1 TC
WHERE T.tutorielControle='non'
GROUP BY TC.titreCategorieNv1"
)
->getResult();
$response = new Response();
$response->setStatusCode(Response::HTTP_OK);
$response->setContent(json_encode($result));
$response->headers->set('Content-Type', 'application/json');
return $response;
default:
break;
}
}
}

You can do a repository (more infos here : http://symfony.com/fr/doc/current/book/doctrine.html )
And you could use Doctrine Query Language.
But I think your struture is wrong and it wold be better to have a category, this category has a parent category, ...
So you'll have for example a rootcatégory who has childs named "Bricolage", "Sport", ...
"Bricolage" would have, for exemple a category "Peinture" as child, and so on ;)
