Question

我一直在尝试向用户添加多辆车，但我总是会遇到此错误，我一直在网上搜索答案已有2天了，但我仍然卡住了P.S。：我是Symfony and Doctrine

的新手

<?php
namespace CarsBundleController;
use SymfonyBundleFrameworkBundleControllerController;
use SymfonyComponentHttpFoundationResponse;
use SymfonyComponentHttpFoundationRedirectResponse;
use SymfonyComponentHttpFoundationRequest;
use DoctrineORMEntityRepository;
class CarsController extends Controller
{
    public function addCarsAction($iduser,$carName,$carPrice,$carVIN)
    {
        $cars = new cars();
        $cars->setPic('')
             ->setName($carName)
             ->setModle(Null)
             ->setPrice($carPrice)
             ->setVin($carVIN)
             ->setIdUser($iduser);
        //$this->forward('acme.controller.tagclass:ParseWebsite',array($categoryid));
            $em1 = $this->forward('app.cars_controller')
                        ->getDoctrine()->getManager()
                        ->getRepository('OBCarsTest1Bundle:cars')
                        ->persist($cars)
                        ->flush();
        }
        public function addCarsToUserAction()
        {       
            $this->addCarsAction(1,'bmw',45000,'o102384');
            //$this->addCarsAction(1,'mercedes',53000,'o224384');
            //$this->addCarsAction(1,'nisan',25000,'o686495');
            //$this->addCarsAction(2,'golf',44000,'o659826');
            //$this->addCarsAction(2,'toyota',23000,'o255325');
            //test if it works
            $repository = $this->getDoctrine()
                ->getRepository('OBCarsTest1Bundle:cars');      
            $cars = $repository->findOneById(3);
            return new Response('Created cars : n '.$cars);
        }
    }

Answer 1

您对它的思考只是使用： $em1 = $this->getDoctrine()->getManager()代替

$em1 = $this->forward('app.cars_controller')->getDoctrine()->getManager()

并且为了持久性，假设您有一个propper orm映射您只需要添加： $em1->persist($cars); $em1->flush();，它将其保存在数据库
