Question

我尝试连接两个表并使用doctrine查询构建器获取列值。

这是我的代码

public function getLatestProduct($amount) {
        $em = $this->container->get('doctrine.orm.entity_manager');

        $qb = $em->createQueryBuilder();

        $qb->select('p.id, p.category, p.productTitle, p.price, p.description, pi.imgUrl')
                ->from('EagleShopBundle:Products', 'p')
                ->leftJoin('EagleShopBundle:ProuctImage', 'pi', \Doctrine\ORM\Query\Expr\Join::WITH, 'pi.productId = p.id')
                ->orderBy('p.id', 'DESC')
                ->groupBy('p.id')
                ->setMaxResults($amount);

        return $qb->getQuery()->getResult();
    }

这就是我所说的

public function indexAction() {
        $latest = $this->getLatestProduct(8);
        $isfeatured = $this->getfeaturedProduct(8);

        return $this->render("EagleShopBundle:global:home.html.twig", array(
                    'image_path' => '/bundles/eagleshop/images/',
                    'latest_products' => $latest,
                    'isfeatured' => $isfeatured
        ));
    }

但是当我尝试称这种方法时，我遇到了这个问题，

[语义错误]第0行，第15列附近＆＃39;类别，p.productTitle，＆＃39;：错误：无效的PathExpression。必须是StateFieldPathExpression。

我认为此代码与问题有关，

$ qb-＆gt;选择（＆＃39; p.id，p.category，p.productTitle，p.price，p.description， pi.imgUrl＆＃39）

这是我的产品实体
