坚持一对一关系中的实体

Question

我有一张表Quantity和Product。我试图在产品表格中保留表格数量的id。

如果产品销售时可以购买一次产品，我希望sold_id由表格数量的ID设置。

我试过这样做：

foreach ($entities as $entity) {
            $entities = new Post();
            $entities->setSold($entity);
            $em->persist($entities);
            $em->flush();
            }

不幸的是sold_id仍为null。

产品

/**
 * @ORM\OneToOne(targetEntity="Quantity", cascade={"remove"})
 * @ORM\JoinColumn(name="sold_id", referencedColumnName="id")
 */
protected $sold;

数量

    /**
     * @ORM\ManyToOne(targetEntity="Commandes", inversedBy="quantities")
     * @ORM\JoinColumn(name="order_id", referencedColumnName="id")
     */
    protected $desk1;

    /**
     * @ORM\ManyToOne(targetEntity="Post")
     * @ORM\JoinColumn(name="product_id", referencedColumnName="id")
     */
    protected $desk2;

    /** @ORM\Column(name="quantity", type="integer") */
    protected $quantity;

添加

     * @Route("/complete", name = "complete")
     * @Template()

    public function completeAction(Request $request)
    {   $session = $this->getRequest()->getSession();
        $token = $this->get('payum.security.http_request_verifier')->verify($request);
        $gateway = $this->get('payum')->getGateway($token->getGatewayName());
        $gateway->execute($status = new GetHumanStatus($token));

        $cart = $session->get('cart');
        $model = $status->getModel();
        // you have order and payment status
        // so you can do whatever you want for example you can just print status and payment details.
        if ($status->isCaptured()) {
            $this->getRequest()->getSession()->getFlashBag()->set(
                'paid',
                'Your payment has been successfully processed.Thank you! NOTE: You will receive an email shortly'
            );
            $commande->setStatuss("PAID");
            //$this->get('flyMailer')->sendSuccessMessageBuyer($commande);
            //$this->get('flyMailer')->sendSuccessMessageSeller($commande);
            $commande->setAmountpaid($model['PAYMENTREQUEST_0_AMT']);
            $commande->setIsActive(true);

            foreach ($entities as $entity) {
                $entities = new Quantity();
                $entities->setDesk2($entity);
                $entities->setDesk1($commande);
                $entities->setQuantity($cart[$entity->getId()]);
                $em->persist($entities);

            }

            $em->flush();

            }

            $commande->setAmountpaid($model['PAYMENTREQUEST_0_AMT']);
            $commande->setIsActive(true);


        }


        if ($status->isFailed() || $status->isCanceled()) {
            $this->getRequest()->getSession()->getFlashBag()->set(
                'canceled',
                'your payment has been canceled'
            );
            $commande->setStatuss("CANCELED");

            $commande->setAmountpaid($model['PAYMENTREQUEST_0_AMT']);
            $commande->setIsActive(true);

        }

        $em = $this->getDoctrine()->getManager();
