Question

我有一个产品实体，当我添加具有多个图像的产品时，每个产品都与多个图像相关，但是如果我移除产品，则会出现错误

在删除功能中，我有以下代码：

public function delete(Request $req,Products $product){

     if($this->isCsrfTokenValid('delete'. $product->getId(),$req->get('_token'))){

            foreach ($product->getImages() as $image) {


               $product->removeImage($image);
               $this->em->remove($image);
                $this->em->persist($image);

            }
        $this->em->remove($product);
        $this->em->flush();


        $this->addFlash('success',"product deleted");

          }
         return $this->redirectToRoute("admin.index");

     }

在我进行的编辑中

  public function edit(Products $product ,Request $req):Response{

    $originalImages = array();
    if($product){

    foreach ($product->getImages() as $image) {
        $originalImages[] = $image;
    }

    $editForm = $this->createForm(ProductsTypeForm::class,$product);

           $editForm->handleRequest($req);
         if($editForm->isSubmitted()&&$editForm->isValid()){
            foreach ($product->getImages() as $image) {
                foreach ($originalImages as $key => $toDel) {
                    if ($toDel->getId() === $image->getId()) {
                        unset($originalImages[$key]);
                    }
                }
            }

            // remove the relationship between the image and the Product
            foreach ($originalImages as $image) {

                $product->removeImage($image);
                $this->em->remove($image);
                $this->em->persist($image);

            }
            $this->em->persist($product);
            $this->em->flush();

             $this->addFlash('success',"changed");
             return $this->redirectToRoute('admin.index');
    }
}

    return $this->render('pages/admin/edit.html.twig',[
        'item'=>$product,
        'form'=>$editForm->createView()
    ]);
}

在“图像”实体中，我具有双向的多对一关系。关系已正确删除，但与产品相关的图像未删除任何人都可以帮助我

我使用vichUploaderBundle我得到的错误是在属性路径“ imageName”处给出的“ string”，“ NULL”类型的预期参数
