Symfony2 Table with 3 entity in Twig - php

Question

First of all, sorry by advance for my english which is not perfect.
I have a problem for days by reporting 3 doctrine entity in a Twig Table template.
It's a table for manage stocks at work. I have different materials which have each different sizes. Each couple (1 material + 1 size) got a number as amound to order.
So I first created 3 entity :
Stock (represent materials) ManyToMany Dimension (represent sizes)
Besoin (needs) got a ManyToOne relation with both Stock and Dimension.
Then, I created few Stocks, Dimensions and needs with my forms to get a test database.
The goal is now to create a double entry table with the dimensions list, Stocks list and in each cell the needed number.
It's in this step that I have bugs.
For now I can give you my code and hope someone can help me by giving me a tips.
Controller :
public function commandeAction()
{
$em = $this->getDoctrine()->getManager();
$materiauxlist = $em->getRepository('TGComptaBundle:Stock')->findAll();
$dimensionslist = $em->getRepository('TGComptaBundle:Dimension')->findAll();
$tab1 = array_merge($materiauxlist, $dimensionslist);
$besoins = array();
foreach ($materiauxlist as $stock) {
foreach ($dimensionslist as $dimension) {
$besoin = $em->getRepository('TGComptaBundle:Besoin')->findBesoins($stock, $dimension);
}
}
return $this->render('TGProdBundle:Projet:stocks.html.twig', array(
'materiauxlist' => $materiauxlist,
'dimensionslist' => $dimensionslist,
'besoin' => $besoin));
}
View :
{% block tgprod_body %}
<div class="well">
<table class="table table-hover table-bordered">
<thead>
<tr>
<th>#</th>
{% for dimension in dimensionslist %}
<th>{{ dimension.name }}</th>
{% endfor %}
</tr>
</thead>
{% for stock in materiauxlist %}
<tr>
<td>{{ stock.name }}</td>
{% for dimension in dimensionslist %}
{% if besoin %}
<td>{{ besoin.nombre }}</td>
{% else %}
<td>X</td>
{% endif %}
{% endfor %}
</tr>
{% endfor %}
</table>
</div>
{% endblock %}
Repository :
public function findBesoins($stock, $dimension)
{
$qb = $this->createQueryBuilder('b');
$qb
->where('b.stock = :stock')
->andwhere('b.dimension = :dimension')
->setParameter('stock', $stock)
->setParameter('dimension', $dimension);
$qb
->getQuery()
->getResult();
}
My actual problem is : I have X in all cells

Answer 1

Before I asked your help I tried :
foreach ($materiauxlist as $stock) {
foreach ($dimensionslist as $dimension) {
$besoin = $em->getRepository('TGComptaBundle:Besoin')->findBesoins($stock, $dimension);
$besoins[] = $besoin;
}
}
and :
<table class="table table-hover table-bordered">
<thead>
<tr>
<th>#</th>
{% for dimension in dimensionslist %}
<th>{{ dimension.name }}</th>
{% endfor %}
</tr>
</thead>
{% for stock in materiauxlist %}
<tr>
<td>{{ stock.name }}</td>
{% for dimension in dimensionslist %}
{% for besoin in besoins %}
{% if besoin %}
<td>{{ besoin.nombre }}</td>
{% else %}
<td>X</td>
{% endif %}
{% endfor %}
{% endfor %}
</tr>
{% endfor %}
</table>
But it was wrong result (I had like 10000 X on each row)
I thinked it's the "{% for besoin in besoins %}" which is wrong, it should be something like "{% for besoin.dimension.stock in besoins %}" but I can't write this in twig.
and I tried something like this to :
$table = array('stock' => $stock, 'dimension' => $dimension, 'besoin' => $besoin);
$besoins[] = $table;
when I do a { dump() } in Twig I have array with number of stock x number of dimension and all with a null besoin so it seems strange ... and finally I didn't find how to render this array in my table so I let this solution away :/
