模板渲染期间抛出异常（"Parameter "id" for route "url" must match "[^/]++" ("" given) to generate a corresponding URL."

Question

我在这里创建了一个删除按钮：

_delete_form.html.twig

<form method="post" action="{{ path('finals_delete', {'id': final.id}) }}" onsubmit="return confirm('Are you sure you want to delete this item?');">
<input type="hidden" name="_token" value="{{ csrf_token('delete' ~ final.id) }}">
<button class="btn btn-success" style="margin-top: 10px">Verwijderen</button>

我将其包含在编辑页面中，如下所示：

   {{ include('finals/_form.html.twig', {'button_label': 'Opslaan'}) }}

    <button class="btn btn-success"><a href="{{ path('finals_index') }}">Terug naar lijst</a>  </button>

   {{ include('finals/_delete_form.html.twig') }}

删除的控制器操作：

    /**
 * @Route("/{id}", name="finals_delete", methods={"POST"})
 */
public function delete(Request $request, Finals $final): Response
{
    if ($this->isCsrfTokenValid('delete'.$final->getId(), $request->request->get('_token'))) {
        $entityManager = $this->getDoctrine()->getManager();
        $entityManager->remove($final);
        $entityManager->flush();
    }

    return $this->redirectToRoute('finals_index');
}

编辑的控制器操作：

/**
 * @Route("/{id}/edit", name="finals_edit", methods={"GET","POST"})
 */
public function edit(Request $request, Finals $final): Response
{
    $final = new Finals();
    $form = $this->createForm(FinalsType::class, $final);
    $form->handleRequest($request);

    $imageFile = $form->get('imageTeam1')->getData();

    //If function to only process an imagine if its uploaded
    if ($imageFile) {

        $originalFilename = pathinfo($imageFile->getClientOriginalName(), PATHINFO_FILENAME);

        //Remove unwanted characters from filename
        $safeFilename = transliterator_transliterate('Any-Latin; Latin-ASCII; [^A-Za-z0-9_] remove; Lower()', $originalFilename);
        $newFilename = $safeFilename.'-'.uniqid().'.'.$imageFile->guessExtension();


        //Move file to image dir
        try {
            $imageFile->move($this->getParameter('images_directory'),$newFilename);
        }   catch (FileException $e) {
            $this->addFlash('danger', 'Er is iets fout gegaan probeer het opnieuw');
        }

        $final->setImageTeam1($newFilename);


        $this->getDoctrine()->getManager()->flush();
        return $this->redirectToRoute('finals_index');
    }

    return $this->render('finals/edit.html.twig', [
        'final' => $final,
        'form' => $form->createView(),
    ]);
}

所有这些都是使用 bin/console make:crud 命令创建的，我用完全相同的按钮和代码制作了多个这样的页面，但由于某种原因只有这个出现此错误：

An exception has been thrown during the rendering of a template ("Parameter "id" for route "finals_delete" must match "[^/]++" ("" given) to generate a corresponding URL.").

在 C:\xampp\htdocs\Freulepartij\templates\finals_delete_form.html.twig（第 1 行）

我一点击我的编辑页面就抛出错误（当删除按钮刚刚被渲染并且它背后的功能没有被执行时？）我觉得很奇怪。当我删除包含时，我可以进入我的编辑页面但是我的编辑表单也不会更新记录，所以它不知道如何处理数据？我真的很困惑，因为当我单击没有删除按钮的编辑页面时，id 就在 url 中

更新 1

按照 Gary Houbre 的建议，我替换了

 {{ include('finals/_delete_form.html.twig' }}

和

{{ include('finals/_delete_form.html.twig' , {'final': final.id}) }}

现在出现此错误：

Impossible to access an attribute ("id") on a null variable.

但是我正在查看我的数据库，并且在这个 table 中只有 2 条记录都有 id，所以我不知道它是如何得到空值的？

更新 2

我在 symfony 日志中找到了这个，它确认了正确的 ID“7” 所以这让我更加困惑..

SELECT t0.id AS id_1, t0.team1 AS team1_2, t0.team2 AS team2_3, t0.image_team1 AS image_team1_4, t0.image_team2 AS image_team2_5, t0.paragraph AS paragraph_6, t0.eersten_p1 AS eersten_p1_7, t0.eersten_p2 AS eersten_p2_8, t0.punten_p1 AS punten_p1_9, t0.punten_p2 AS punten_p2_10 FROM finals t0 WHERE t0.id = ?

[ "7" ]

Answer 1

进入你的edit.html.twig，你的包含文件所在的行_delete.html.twig

您需要添加参数'id'。例如：

{% include 'template.html' with {'foo': 'bar'} %}

我在这个 link

中遵循此文档 Twig

Answer 2

正如加里评论中指出的那样，我在编辑功能中有一个新调用，显然不属于那里，所以这就是我的问题所在

模板渲染期间抛出异常（"Parameter "id" for route "url" must match "[^/]++" ("" given) to generate a corresponding URL."

Exception thrown during the rendering of a template("Parameter "id" for route "url" must match "[^/]++" ("" given) to generate a corresponding URL.")
