TYPO3 Extbase 1:n视图中未显示的关系对象

我目前正在学习extbase和fluid。我阅读了这篇SO文章，以便在我的分机中建立关系。我有角色和人。N人可以有M个角色。现在后端一切正常。在前端使用f:debug时，我看不到对象。我的问题是extbase没有正确地解决这个关系（我想是吧？）

这是我的关系课：

<?php
namespace Vendor\People\Domain\Model;
/**
 * Class PersonRoleRelation
 * @scope prototype
 * @entity
 * @package Vendor\People\Domain\Model
 */
class PersonRelation extends \TYPO3\CMS\Extbase\DomainObject\AbstractEntity {
    /**
     * @var \Vendor\People\Domain\Model\Person
     */
    protected $person;
    /**
     * @var \Vendor\People\Domain\Model\Role
     */
    protected $role;
    /**     
     * @param \Vendor\People\Domain\Model\Person $person
     */
    public function setPerson($person) {
        $this->person = $person;
    }
    /**
     * @return \Vendor\People\Domain\Model\Person
     */
    public function getPerson() {
        return $this->person;
    }
    /**
     * @param \Vendor\People\Domain\Model\Role $role
     */
    public function setRole($role) {
        $this->role = $role;
    }
    /**
     * @return \Vendor\People\Domain\Model\Role
     */
    public function getRole() {
        return $this->role;
    }
}

TCA配置：

tx_people_domain_model_person.php：

所以问题是我需要在前端访问那些相关的对象（或者一个人的角色）。

---

编辑：我想我现在对我需要的关系类型有点困惑。一个人可以有n个角色。无论如何，我不想把人们和角色联系起来。我只想创建角色，然后将角色分配给不同的人。所以我想这应该是1:n的关系。如果这使它变得更容易的话。

解决方案是在我的Person类中添加以下方法和变量：

/**
 * roles
 *
 * @var \TYPO3\CMS\Extbase\Persistence\ObjectStorage<\Domain\People\Domain\Model\Role>
 */
protected $roles = NULL;

/**
 * __construct
 */
public function __construct() {
    //Do not remove the next line: It would break the functionality
    $this->initStorageObjects();
}

/**
 * Initializes all ObjectStorage properties
 * Do not modify this method!
 * It will be rewritten on each save in the extension builder
 * You may modify the constructor of this class instead
 *
 * @return void
 */
protected function initStorageObjects() {
    $this->roles = new \TYPO3\CMS\Extbase\Persistence\ObjectStorage();
}

/**
 * Adds a Role
 *
 * @param \Domain\People\Domain\Model\Role $role
 * @return void
 */
public function addRole(\Domain\People\Domain\Model\Role $role) {
    $this->roles->attach($role);
}

/**
 * Removes a Role
 *
 * @param \Domain\People\Domain\Model\Role $roleToRemove The Role to be removed
 * @return void
 */
public function removeRole(\Domain\People\Domain\Model\Role $roleToRemove) {
    $this->roles->detach($roleToRemove);
}

/**
 * Returns the roles
 *
 * @return \TYPO3\CMS\Extbase\Persistence\ObjectStorage<\Domain\People\Domain\Model\Role> $roles
 */
public function getRoles() {
    return $this->roles;
}

/**
 * Sets the roles
 *
 * @param \TYPO3\CMS\Extbase\Persistence\ObjectStorage<\Domain\People\Domain\Model\Role> $roles
 * @return void
 */
public function setRoles(\TYPO3\CMS\Extbase\Persistence\ObjectStorage $roles) {
    $this->roles = $roles;
}

/**
*角色
*
*@var\TYPO3\CMS\Extbase\Persistence\ObjectStorage
*/
受保护的$roles=NULL；
/**
*_uuu构造
*/
公共函数构造（）{
//不要删除下一行：它会破坏功能
$this->initStorageObjects（）；
}
/**
*初始化所有ObjectStorage属性
*不要修改此方法！
*它将在扩展生成器中的每次保存时重写
*您可以修改此类的构造函数
*
*@返回无效
*/
受保护的函数initStorageObjects（）{
$this->roles=new\TYPO3\CMS\Extbase\Persistence\ObjectStorage（）；
}
/**
*添加一个角色
*
*@param\Domain\People\Domain\Model\Role$Role
*@返回无效
*/
公共函数addRole（\Domain\People\Domain\Model\Role$Role）{
$this->roles->attach（$role）；
}
/**
*删除角色
*
*@param\Domain\People\Domain\Model\Role$Role删除要删除的角色
*@返回无效
*/
公共函数移除OLE（\Domain\People\Domain\Model\Role$roleToRemove）{
$this->roles->detach（$roleToRemove）；
}
/**
*返回角色
*
*@return\TYPO3\CMS\Extbase\Persistence\ObjectStorage$roles
*/
公共函数getRoles（）{
返回$this->roles；
}
/**
*设置角色
*
*@param\TYPO3\CMS\Extbase\Persistence\ObjectStorage$roles
*@返回无效
*/
公共函数集合角色（\TYPO3\CMS\Extbase\Persistence\ObjectStorage$roles）{
$this->roles=$roles；
}

将类放在这里。90%的用户不会打开链接。你不需要将关系作为一个类，至少对于TYPO3是noc。如果您的应用程序需要它（例如，如果您需要关系上的属性），请创建两个关系：1:n从

RolePerson

到

Role

和1:n从

RolePerson

到

Person

。此外，请显示相应的

ext\u表。sql

文件和您的模型的TCA配置，如果你已经做了一些的话，还有任何打字稿映射。我认为这可能是缺少setter和/或命名约定的问题。此外，我获得了正确数量的关系对象，但无法访问它的角色/人员对象。。它们显然是空的。我想说明的是，基本上能够访问与该人相关的每个角色。所以我想有一个类person的对象和一个类成员role。
