mysql - Doctrine 交响曲

Question

您好，我正在使用 symfony 的 Doctrine ，我想进行此连接

$select ="SELECT c.sku, t.title, p.stock FROM BackendBundle:CartItems c 
                LEFT JOIN BackendBundle:PartInfo p ON p.nkrCode= c.sku
                LEFT JOIN BackendBundle:PartInfoTitles t ON t.internalCode = c.sku
                WHERE c.cart=".$cart;
                $em = $this->getDoctrine()->getManager();
                $query = $em->createQuery($select);
                $part = $query->getResult();

问题是 c.cart 是一个对象，因为它有一个外键，我如何使用 Doctrine 得到它？

试试这个

$select ="SELECT c.sku, t.title, p.stock FROM BackendBundle:CartItems c 
                LEFT JOIN BackendBundle:PartInfo p ON p.nkrCode= c.sku
                LEFT JOIN BackendBundle:PartInfoTitles t ON t.internalCode = c.sku
                WHERE c.cart= :cart";
                $em = $this->getDoctrine()->getManager();
                $query = $em->createQuery($select)->setParameter('cart',$cart->getId());
                $part = $query->getResult();
