当我查看www.example.com/product/10时，此产品已链接至a User Id.现在，我只想显示与该产品Comment相关联的User id我正在观看。
表Comment是表User的链接，因此每条评论都是用户ID。表Product（Post）也链接到表用户，每个产品都有用户ID。
现在，表格Comment和Product尚未链接，我认为它们应该可以执行查询，但我不确定。
我使用FosCommentBundle作为评论。

{
$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.');

添加
<?php

use Application\Sonata\UserBundle\Entity\User;
use Doctrine\ORM\EntityRepository;

从评论到帖子（产品）的关系：

*/

return $this;
}
/**

*
* @return \FLY\BookingsBundle\Entity\Post
*/
public function getPost()
{
return $this->post;
}
控制器中的修改：
public function productAction($id, Request $request, $post)
{
$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.');
}
$post = 'thread_id';
$thread = $em->getRepository('ApplicationSonataCommentBundle:Comment')->getCommentsForSinglePost($post);
if (null === $thread) {
$thread = $this->container->get('fos_comment.manager.thread')->createThread();
$thread->setId($post);
$thread->setPermalink($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,'post' => $post,
'thread' => $thread));
}
错误：
控制器 ＆＃34; FLY \ BookingsBundle \控制器\ PostController中:: productAction（）＆＃34; 要求您为＆＃34; $ post＆＃34;提供价值。争论（因为 没有默认值，或者因为存在非可选参数 在此之后）。
答案 0 :(得分：0)
考虑到Many-To-One与Comment之间存在Product关联。以下是在CommentRepository中编写新方法以获取单个产品的注释列表的方法。
/**
* 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();
}
您可以根据自己的要求添加任何其他条件。或者添加排序或分页等。
注意：我还没有添加用户关联。如果您还有其他需要，请告诉我。
