Does Doctrine's createQueryBuilder bypass the Entities getter methods? - doctrine-orm

Question

I'm very new to Symfony coming from a Kohana background and am having a rough time getting used to Doctrine.
Currently I have a product table which I am inner joining some other tables using the createQueryBuilder and need add some extra logic in the getter method for the product Entity. However it would seem that the getter methods aren't even being used. Here is some snippets of my code :
//From AppBundle\Controller\ProductController
$repository = $this->getDoctrine()->getRepository('AppBundle:Product');
$products = $repository->findWithLimitNew(24);
//From AppBundle\Repositories\ProductRepository
public function findWithLimitNew($limit=1)
{
$em = $this->getEntityManager();
$qb = $em->createQueryBuilder();
$qb->select( 'p.name', 'p.id', 'p.slug', 'pc.name AS catname' )
->from('AppBundle\Entity\Product', 'p')
->innerJoin(
'AppBundle\Entity\ProductAttributes',
'pa',
\Doctrine\ORM\Query\Expr\Join::WITH,
'p.id = pa.productId'
)
->innerJoin(
'AppBundle\Entity\ProductCategories',
'pc',
\Doctrine\ORM\Query\Expr\Join::WITH,
'pa.value = pc.id'
)
->where('pa.type = 1')
->where('pa.default = 1')
->setMaxResults($limit);
return $qb->getQuery()->getResult();
}
// From AppBundle\Entity\Product
/**
* Get name
*
* #return string
*/
public function getName()
{
#return $this->name; //<--Commenting this out for now
return 'Some stupid string';
}
// From index.twig.html
{% for product in products %}
<h1>{{product.name}}</h1>
{% endfor %}
Now as you can see I have the getter method getName() returning a string, but when the view is rendered I get the product name, not the string I'm returning. What gives?

#Cerad has a point. At first glance your query looks like DQL not QB. However now I realize your code is correct, you can simplify your QueryBuilder (QB) code quite a bit:
$qb->select( 'p' )
->from('AppBundle:Product', 'p')
->innerJoin(
'AppBundle:ProductAttributes',
'pa',
'WITH',
'p.id = pa.productId'
)
->innerJoin(
'AppBundle:ProductCategories',
'pc',
'WITH',
'pa.value = pc.id'
)
->where('pa.type = 1')
->andWhere('pa.default = 1')
->setMaxResults($limit);
Notice I use a "andWhere", but your original had a additional "where". I'm surprised that works and didn't throw and error.
Also, I think the main problem is that you just need to understand the returned results. Then in your twig, you don't call the attribute, but instead call the getter like so:
// From index.twig.html
{% for product in products %}
<h1>{{ product.getName }}</h1>
{% endfor %}
Can you try these changes? I think calling the getter in the Twig template is the problem.
This might not work. Let us know if it doesn't.
