Php Symfony2.3多对多形式

我有一些问题让多对多的人在我的表格上工作

我的表格如下所示：

用户（FOSUserBundle）
成员（自定义类）
区域（自定义类）

成员窗体是用户窗体的子窗体，区域窗体是成员窗体的子窗体

首先，我得到的错误是：

属性“region”或方法“setRegion（）”、“\u set（）”或“\u call（）”都不存在，并且在类“Netsite\Bundle\AdminBundle\Entity\Member”中都没有公共访问权限

当我提交表单时，它会点击：

$form->handleRequest($request);

以下是所有相关代码：

Member.orm.yml

Netsite\Bundle\AdminBundle\Entity\Member:
type:  entity
table: member
id:
    id:
        type: integer
        generator:
            strategy: AUTO
fields:
    security_question:
        type: string
        length: 255
    security_answer:
        type: string
        length: 255
----- SNIP -----
manyToMany:
    region:
        targetEntity: Region
        cascade: ["persist", "remove"]

Entity\Member.php

Entity\Region.php

<?php

namespace Netsite\Bundle\AdminBundle\Entity;

use Doctrine\ORM\Mapping as ORM;

/**
 * Region
 */
class Region
{
    /**
     * @var integer
     */
    private $id;

    /**
     * @var string
     */
    private $region;


    /**
     * Get id
     *
     * @return integer 
     */
    public function getId()
    {
        return $this->id;
    }

    /**
     * Set region
     *
     * @param string $region
     * @return Region
     */
    public function setRegion($region)
    {
        $this->region = $region;

        return $this;
    }

    /**
     * Get region
     *
     * @return string 
     */
    public function getRegion()
    {
        return $this->region;
    }
}

我想您应该在MemberType.php中替换：

$builder->add('region', new RegionType())

与

这将呈现一个带有标记为Region:：Region的复选框的区域（顺便说一句，混淆的命名方案应该只是“名称”）。多个复选标记将通过多个M2M条目反映出来

Netsite\Bundle\AdminBundle\Entity\Region:
type:  entity
table: region
id:
    id:
        type: integer
        generator:
            strategy: AUTO
fields:
    region:
        type: string
        length: 255

<?php

namespace Netsite\Bundle\AdminBundle\Entity;

use Doctrine\ORM\Mapping as ORM;

/**
 * Region
 */
class Region
{
    /**
     * @var integer
     */
    private $id;

    /**
     * @var string
     */
    private $region;


    /**
     * Get id
     *
     * @return integer 
     */
    public function getId()
    {
        return $this->id;
    }

    /**
     * Set region
     *
     * @param string $region
     * @return Region
     */
    public function setRegion($region)
    {
        $this->region = $region;

        return $this;
    }

    /**
     * Get region
     *
     * @return string 
     */
    public function getRegion()
    {
        return $this->region;
    }
}

<?php
