传递给 App\Entity\MyOrders::setOrderstatus() 的参数 1 必须是 App\Entity\OrderStatus 的实例或 null，给定整数

问题描述

拜托，我是 symfony 的新手，我正在尝试将引用 ID 保存到表中，但收到这些错误“传递给 App\Entity\MyOrders::setorderstatus() 的参数 1 必须是 App\Entity\OrderStatus 的实例或 null，给定整数，在 C:\xampp\htdocs\symphonycrud\src\Repository\MyOrdersRepository.PHP 第 69 行中调用” 请不要说此代码基于 symfony 5+，我尝试了很多选项但无济于事。 提前致谢。

我有一个 MyOrders 实体

namespace App\Entity;

use App\Repository\MyOrdersRepository;
use Doctrine\ORM\Mapping as ORM;

/**
 * @ORM\Entity(repositoryClass=MyOrdersRepository::class)
 */
class MyOrders
{
    /**
     * @ORM\Id
     * @ORM\GeneratedValue
     * @ORM\Column(type="integer")
     */
    private $id;

    /**
     * @ORM\Column(type="string",length=50)
     */
    private $order_code;

    /**
     * @ORM\Column(type="decimal",precision=10,scale=2)
     */
    private $order_total;

    /**
     * @ORM\Column(type="decimal",scale=2)
     */
    private $order_discount;

    /**
     * @ORM\Column(type="string",length=255)
     */
    private $order_items;

    /**
     * @ORM\Column(type="string",length=255)
     */
    private $shipping_details;

    /**
     * @ORM\ManyToOne(targetEntity=OrderStatus::class,inversedBy="myOrders")
     * @ORM\JoinColumn(nullable=false)
     */
    private $orderstatus;


    public function getId(): ?int
    {
        return $this->id;
    }

    public function getorderCode(): ?string
    {
        return $this->order_code;
    }

    public function setorderCode(string $order_code): self
    {
        $this->order_code = $order_code;

        return $this;
    }

    public function getorderTotal(): ?string
    {
        return $this->order_total;
    }

    public function setorderTotal(string $order_total): self
    {
        $this->order_total = $order_total;

        return $this;
    }

    public function getorderdiscount(): ?string
    {
        return $this->order_discount;
    }

    public function setorderdiscount(string $order_discount): self
    {
        $this->order_discount = $order_discount;

        return $this;
    }

    public function getorderItems(): ?string
    {
        return $this->order_items;
    }

    public function setorderItems(string $order_items): self
    {
        $this->order_items = $order_items;

        return $this;
    }

    public function getShippingDetails(): ?string
    {
        return $this->shipping_details;
    }

    public function setShippingDetails(string $shipping_details): self
    {
        $this->shipping_details = $shipping_details;

        return $this;
    }

    public function getorderstatus(): ?OrderStatus
    {
        return $this->orderstatus;
    }

    public function setorderstatus(?OrderStatus $orderstatus): self
    {
        $this->orderstatus = $orderstatus;

        return $this;
    }

  


}

我的第二个实体是 OrderStatus

 namespace App\Entity;

use App\Repository\OrderStatusRepository;
use Doctrine\Common\Collections\ArrayCollection;
use Doctrine\Common\Collections\Collection;
use Doctrine\ORM\Mapping as ORM;

/**
 * @ORM\Entity(repositoryClass=OrderStatusRepository::class)
 */
class OrderStatus
{
    /**
     * @ORM\Id
     * @ORM\GeneratedValue
     * @ORM\Column(type="integer")
     */
    private $id;

    /**
     * @ORM\Column(type="string",length=255)
     */
    private $statusdescription;

    /**
     * @ORM\OnetoMany(targetEntity=MyOrders::class,mappedBy="orderstatus")
     */
    private $myOrders;

    public function __construct()
    {
        $this->myOrders = new ArrayCollection();
    }

   
  
    public function getId(): ?int
    {
        return $this->id;
    }

public function getStatusdescription(): ?string
{
    return $this->statusdescription;
}

public function setStatusdescription(string $statusdescription): self
{
    $this->statusdescription = $statusdescription;

    return $this;
}


/**
 * @return Collection|MyOrders[]
 */
public function getMyOrders(): Collection
{
    return $this->myOrders;
}

public function addMyOrder(MyOrders $myOrder): self
{
    if (!$this->myOrders->contains($myOrder)) {
        $this->myOrders[] = $myOrder;
        $myOrder->setorderstatus($this);
    }

    return $this;
}

public function removeMyOrder(MyOrders $myOrder): self
{
    if ($this->myOrders->removeElement($myOrder)) {
        // set the owning side to null (unless already changed)
        if ($myOrder->getorderstatus() === $this) {
            $myOrder->setorderstatus(null);
        }
    }

    return $this;
}

public function __toString()
{
    return $this->statusdescription;
}
 

}

这是我的存储库 MyordersRepository

namespace App\Repository;

use App\Entity\MyOrders;
use App\Entity\OrderStatus;
use Doctrine\ORM\EntityManagerInterface;
use Doctrine\Persistence\ManagerRegistry;
use Doctrine\Bundle\DoctrineBundle\Repository\ServiceEntityRepository;

/**
 * @method MyOrders|null find($id,$lockMode = null,$lockVersion = null)
 * @method MyOrders|null findOneBy(array $criteria,array $orderBy = null)
 * @method MyOrders[]    findAll()
 * @method MyOrders[]    findBy(array $criteria,array $orderBy = null,$limit = null,$offset = null)
 */
class MyOrdersRepository extends ServiceEntityRepository
{
    private $manager;
    public function __construct(ManagerRegistry $registry,EntityManagerInterface $manager)
    {
        parent::__construct($registry,MyOrders::class);
        parent::__construct($registry,OrderStatus::class);
        $this->manager=$manager;
       
    }

    // /**
    //  * @return MyOrders[] Returns an array of MyOrders objects
    //  */
    /*
    public function findByExampleField($value)
    {
        return $this->createqueryBuilder('m')
            ->andWhere('m.exampleField = :val')
            ->setParameter('val',$value)
            ->orderBy('m.id','ASC')
            ->setMaxResults(10)
            ->getQuery()
            ->getResult()
        ;
    }
    */

    /*
    public function findOneBySomeField($value): ?MyOrders
    {
        return $this->createqueryBuilder('m')
            ->andWhere('m.exampleField = :val')
            ->setParameter('val',$value)
            ->getQuery()
            ->getoneOrNullResult()
        ;
    }
    */

    
    public function createorder($order_code,$order_total,$order_discount,$order_items,$shipping_details,$order_status)
    {
        //$entityManager = $this->getDoctrine()->getManager();
        $neworders=new MyOrders();
        //$os=new OrderStatus();
        $neworders
        ->setorderCode($order_code)
        ->setorderTotal($order_total)
        ->setorderdiscount($order_discount)
        ->setorderItems($order_items)
        ->setShippingDetails($shipping_details)
        ->setorderstatus($order_status);

        $this->manager->persist($neworders);
        //$this->manager->persist($os);

        $this->manager->flush();
    }

这是我的控制器 MyOrdersController

 /**
 * @Route("/ordeRSS",methods={"GET"})
 */
public function ordeRSS(EntityManagerInterface $em,Request $request)//: JsonResponse
{
    //$data = json_decode($request->getContent(),true);
    $OrderStatus=new OrderStatus();
    //$orders = new MyOrders();
    $orderstatusss=$em->getRepository(OrderStatus::class)->findAll(['myOrders'=>$this->getUser()->getId()]);
    //$orderstatusss=$em->getRepository(OrderStatus::class)->findAll();
    //return new Response(array('hello'=>$orderstatusss));
    $as = $orderstatusss['0'];
    //dump();
  
    
    //die();
    $entityManager = $this->getDoctrine()->getManager();
    $order_code='003';
    $order_total=500;
    $order_discount='0';
    $order_items='dresss';
    $shipping_details='test shipping';
    $order_status=(8);
    //$entityManager->persist($order_status);
    $this->myordersrepository->createorder($order_code,$order_status);
}

解决方法

这不是 symfony 问题，您在方法 setOrderstatus 中指定只有 OrderStatus 对象或 null 可以作为参数传递，但是您在那里传递整数，因此如果您想加载对象，您需要从 DB 加载订单状态

$this->manager->getRepository(OrderStatus::class)->find($order_status);

或者由于您不需要来自该实体的所有数据，您可以只创建 reference。 所以你的创建函数看起来像这样

    public function createorder($order_code,$order_total,$order_discount,$order_items,$shipping_details,$order_status)
{
    //$entityManager = $this->getDoctrine()->getManager();
    $neworders=new MyOrders();
    //$os=new OrderStatus();
    $neworders
    ->setOrderCode($order_code)
    ->setOrderTotal($order_total)
    ->setOrderDiscount($order_discount)
    ->setOrderItems($order_items)
    ->setShippingDetails($shipping_details)
    ->setOrderstatus($this->manager->getReference(OrderStatus::class,$order_status));

    $this->manager->persist($neworders);
    //$this->manager->persist($os);

    $this->manager->flush();
}
