当我创建一个映射了2个实体的表单时，我收到错误

Question

我有2个实体，Topic.php和Post.php我想有这个：

TopicType.php：

<?php

namespace BISSAP\ForumBundle\Form;

use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolverInterface;

        ;
    }

这是我的控制器的一部分，在这里我打电话并使用表格：

public function categoryAction(Request $request)
    {

    $em = $this->getDoctrine()->getManager();

        $topic = new \BISSAP\ForumBundle\Entity\Topic();
        $form = $this->createForm(new TopicType(), $topic);

        $user = $this->getUser();
        $forum = $em->getRepository('BISSAPForumBundle:Forum')->find(1);

        if ($form->handleRequest($request)->isValid()) {

            $topic->setUser($user);
            $topic->setForum($forum);
            $topic->setViewCount(23);
            $topic->setReplyCount(123);
            $topic->setLastPost(25);
            $topic->setSlug('slug_sluggg');
            $topic->setGenre('genre');
            $em->persist($topic);
            $em->flush();


            return $this->render('BISSAPForumBundle:F:topic-forum.html.twig', array('user' => $user, 'topic' => $topic));
        }
            return $this->render('BISSAPForumBundle:F:category-forum.html.twig', array('listTopics' => $listTopics, 'catId' => $catId, 'form' => $form->createView(), 'user' => $user));

    }

我有这个错误：属性＆＃34; subForm＆＃34;也不是其中一种方法＆＃34; getSubForm（）＆＃34;，＆＃34; isSubForm（）＆＃34;，＆＃34; hasSubForm（）＆＃34;，＆＃34; __ get（）＆＃ 34;在课堂上存在且具有公共访问权限＆＃34; BISSAP \ ForumBundle \ Entity \ Topic＆＃34;。

苏尔的方式是错的，因为我认为，我需要给出＆＃34; $ topic objexct＆＃34;和＆＃34; $ post object＆＃34;我用的时候： $ form = $ this-＆gt; createForm（new TopicType（），$ topic）;

我尝试过，添加（收藏）我得到类似的错误！

谢谢你。

Answer 1

您得到的错误是因为您的主题类中没有“子表单”属性。该名称应与主题类中属性的名称相对应。

所以这个：

->add('subForm', new PostType())

应改为

$builder->add('posts','collection', array(  'type' => new PostType()))
