Doctrine Query Builder, between Product and Comment [symfony2] - symfony

Question

When i'm viewing www.example.com/product/10 this product is link to a User Id. Now i would like to show only Comment that is link to the User id of the product a i'm viewing.
The table Comment is link to the table User, so each comment have is user id. The table Product (Post) is also link to the table user , each product have is user id.
For now the table Comment and Product are not yet link , i think they should be so i can perform a query, but i'm not sure.
I'm using FosCommentBundle for the comment.
Controller:
public function productAction($id, Request $request)
{
$session = $this->getRequest()->getSession();
$em = $this->getDoctrine()->getManager();
$findEntities = $em->getRepository('FLYBookingsBundle:Post')->findBy(array('id' => $id));
$entities = $this->get('knp_paginator')->paginate($findEntities, $this->get('request')->query->get('page', 1), 9
);
if ($session->has('cart'))
$cart = $session->get('cart');
else
$cart = false;
if (!$entities) {
throw $this->createNotFoundException('Unable to find Post entity.');
}
$id = 'thread_id';
$thread = $this->container->get('fos_comment.manager.thread')->findThreadById($id);
if (null === $thread) {
$thread = $this->container->get('fos_comment.manager.thread')->createThread();
$thread->setId($id);
$thread->setPermalink($request->getUri());
// Add the thread
$this->container->get('fos_comment.manager.thread')->saveThread($thread);
}
$comments = $this->container->get('fos_comment.manager.comment')->findCommentTreeByThread($thread);
return $this->render('FLYBookingsBundle:Post:product.html.twig', array('entity' => $entities,
'cart' => $cart,'comments' => $comments,
'thread' => $thread));
}

Error:
Controller
"FLY\BookingsBundle\Controller\PostController::productAction()"
requires that you provide a value for the "$post" argument (because
there is no default value or because there is a non optional argument
after this one).

Answer 1

Considering you have Many-To-One association from Comment to Product. Here is how you should write a new method in CommentRepository to get list of comments for a single product.
/**
* Get Comments for a single Product.
* #param Product $product
* #return mixed
*/
public function getCommentsForSingleProduct(Product $product)
{
$qb = $this->createQueryBuilder('c')
->where('c.product = :productId')
->setParameter('productId', $product->getId());
$query = $qb->getQuery();
return $query->execute();
}
You can add any other condition as per your requirement. or add sort, or pagination etc..
Note : I haven't added user association. Let me know if you need anything else.
