评论博客创建不工作的 symfony

Question

你好我试图在博客中添加评论一切都很好它没有显示错误但是当我点击提交时没有任何反应我的意思是它没有将它添加到数据库中我不知道我缺少什么 这就是我在控制器中所拥有的

public function addCommentAction(Request $request, $id)
    {
        $user=$this->getUser();
        if($user==null)
            return $this->redirectToRoute('fos_user_security_login');
        $add_comment = new CommentaireBlog();
        $em = $this->getDoctrine()->getManager();
        $blog = $em->getRepository(Blog::class)->find($id);
        $add_comment->setBlog($blog);
        $add_comment->setUser($user);
        $add_comment->setDate( new \DateTime());

        $form = $this->createFormBuilder($add_comment)

            ->add('contenu', TextareaType::class)
            ->getForm();

        if ($request->getMethod() == 'POST') {
            $form->handleRequest($request);

            if ($form->isSubmitted() && $form->isValid()) {
                $add_comment = $form->getData();
                $em = $this->getDoctrine()->getEntityManager();
                $em->persist($add_comment);
                $em->flush();

                return $this->redirect($this->generateUrl('blog_details'));
            }
        }

        return $this->render('blog/details.html.twig', array(
            'form' => $form->createView(),
            'comment' => $add_comment,
            'blog' => $blog,
        ));

    }

这就是我在 blog.yml 中的内容

comment_new:
    path:     /{id}/details
    defaults: { _controller: "BlogBundle:Blog:addComment" }
    methods:  [GET, POST]

最后这是树枝页面

<div class="comments-form">
                                <h4 class="comments-title">Leave A Reply</h4>

                                    <!-- .row -->
                                    <form action="{{ path('comment_new', { 'id': blog.id }) }}" method="post" >

                                        <textarea id="form_comment" name="form[comment]" required="required" class="form-control comments-textarea" placeholder="Comments*"></textarea>

                                        <input type="submit" class="btn btn-default" />


                                </form>
                            </div>
                        </div>

我刚刚修复了它，我用 detailsaction 显示博客，并且表单处于 addcomment 操作中（我使用 {{form(form)}} 进行了检查，但它没有工作，所以我现在必须在细节操作中完成所有工作看起来像这样

public function detailsAction(Request $request,Blog $blog){

        $user=$this->getUser();
        if($user==null)
            return $this->redirectToRoute('fos_user_security_login');
        $add_comment = new CommentaireBlog();
        $em = $this->getDoctrine()->getManager();

        $add_comment->setBlog($blog);
        $add_comment->setUser($user);
        $add_comment->setDate( new \DateTime());

        $form = $this->createFormBuilder($add_comment)

            ->add('contenu', TextareaType::class)
            ->add('ajouter',SubmitType::class)
            ->getForm();

        if ($request->getMethod() == 'POST') {
            $form->handleRequest($request);

            if ($form->isSubmitted() && $form->isValid()) {
                $add_comment = $form->getData();
                $em = $this->getDoctrine()->getEntityManager();
                $em->persist($add_comment);
                $em->flush();

            }
        }

        return $this->render('blog/details.html.twig', array(
            'form' => $form->createView(),
            'comment' => $add_comment,
            'blog' => $blog,
        ));

    }

树枝看起来像这样：

  {{ form_start(form) }}
                                <div class="row form-group">

                                    <div class="col col-md-3"><label class=" form-control-label">Votre Commentaire  </label></div>
                                    <div class="col-12 col-md-9">{{ form_widget(form.description) }}<small class="form-text text-muted"></small></div>
                                    <div class="col-12 col-md-9">
                                    </div>
                                </div>
                                    {{ form_end(form) }}

无论如何感谢您的帮助

可能有错别字：

->add('contenu', TextareaType::class) // Should be 'comment'

以您使用过的形式：

 <textarea id="form_comment" name="form[comment]" required="required" class="form-control comments-textarea" placeholder="Comments*"></textarea>

好像有映射错误，你可以通过在你的模板中渲染{{ form(form) }}来检查
