如何在symfony 2中呈现复选框窗体

symfony 2中有2个实体与联接表的多对多关系。第一个是certificate，第二个是mayag，联接表是certificate_mayag。证书有许多带有isAvailable、startDate和endDate字段的mayag。mayag有许多证书

我想以复选框形式呈现此关系。该表单包括证书信息和带有复选框的mayag列表以及startdate、enddate和isavailable字段。如何做这个解决方案，哪一个是最好的开发方法

<?php
/**
* Created by PhpStorm.
* User: Mendbayar
* Date: 12/8/13
* Time: 1:00 PM
*/

namespace Mnd\SrdBundle\Entity;

use Doctrine\ORM\Mapping as ORM;

/**
* @ORM\Entity(repositoryClass="Mnd\SrdBundle\Repository\CertifyRepository")
* @ORM\Table(name="Certify")
*/
class Certify {
/**
 * @var integer
 *
 * @ORM\Column(name="id", type="integer")
 * @ORM\Id
 * @ORM\GeneratedValue(strategy="AUTO")
 */
private $id;

/**
 * @ORM\Column(type="string", unique=true, length=50)
 */
protected $certificate_number;
/**
 * @ORM\ManyToOne(targetEntity="CertificateOwner", inversedBy="certificates")
 * @ORM\JoinColumn(name="owner_id", referencedColumnName="id")
 */
protected $owner;

/**
 * @ORM\ManyToOne(targetEntity="Document", inversedBy="certificates")
 * @ORM\JoinColumn(name="document_id", referencedColumnName="id")
 */
protected $document;
/**
 * @ORM\ManyToOne(targetEntity="Action", inversedBy="certificates")
 * @ORM\JoinColumn(name="action_id", referencedColumnName="id")
 */
protected $action;

/**
 * @ORM\OneToMany(targetEntity="Extension", mappedBy="certify")
 */
protected $extensions;

/**
 * @ORM\OneToMany(targetEntity="CertifyMayag", mappedBy="certify")
 */
protected $mayags;

}

}

3个实体具有自动getter setter。

显示一些努力。到目前为止你试过什么？发布一些代码。Devraj Gadhavi，我已经按类更新了我的帖子，我是Symfony 2的新开发人员，我想呈现一个带有Certify信息和复选框列表额外字段的表单，如isavailable、startdate和enddate for mayag of Certify。我的意思是jointable有其他字段，如isavailable、startdate和enddate。如果选中mayag复选框，则表明mayag与认证相关。
