TYPO3 Extbase 1：n关系对象未在视图中公开

Question

我目前正在学习extbase和fluid。 我仔细阅读了TYPO3 extbase和IRRE的这篇文章：用'foreign_selector'添加现有记录以在我的扩展中建立关系。 我有角色和人。 N人可以担任M个角色。 现在，一切在后端正常工作。 在前端时，使用f：debug时看不到对象。 我的问题是extbase无法正确解决该关系（我认为吗？）。

这是我的关系类：

<?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;
    }
}

这是实体人：

<?php
namespace Vendor\People\Domain\Model;
/**
 * Class Person
 * @scope prototype
 * @entity
 * @package Vendor\People\Domain\Model

class Person extends \TYPO3\CMS\Extbase\DomainObject\AbstractEntity {

        $this->roles = new \TYPO3\CMS\Extbase\Persistence\ObjectStorage();
    }
    /**

    protected $roles = NULL;

    /**

     * @validate StringLength(minimum = 3, maximum = 50)
     */
    protected $firstname;

    /**
     * the person's last name
     * @var string
     * @validate StringLength(minimum = 3, maximum = 50)
     */
    protected $lastname;

    /**
     * the person's responsibilities within the company
     * @var string
     */
    protected $role;

    /**
     * Photo
     * @var \TYPO3\CMS\Extbase\Domain\Model\FileReference

    protected $photo;

    /**
     * detail text about the person
     * @var string
     * @dontvalidate
     */
    protected $description;

    /**
     * @param string $firstname
     * @return void
     */
    public function setFirstname($firstname) {
        $this->firstname = $firstname;
    }

    /**
     * @return string
     */
    public function getFirstname() {
        return $this->firstname;
    }

    /**
     * @param string $lastname
     * @return void
     */
    public function setLastname($lastname) {
        $this->lastname = $lastname;
    }

    /**
     * @return string
     */
    public function getLastname() {
        return $this->lastname;
    }

    /**
     * @param string $role
     * @return void
     */
    public function setRole($role) {
        $this->role = $role;
    }

    /**
     * @return string
     */
    public function getRole() {
        return $this->role;
    }

    /**
     * @param string $description
     * @return void
     */
    public function setDescription($description) {
        $this->description = $description;
    }

    /**
     * @return string
     */
    public function getDescription() {
        return $this->description;
    }

    /**
     * @param \TYPO3\CMS\Extbase\Persistence\ObjectStorage<\TYPO3\CMS\Extbase\Domain\Model\FileReference> $photo

    public function getRoles() {
        return $this->roles;
    }

这是角色：

<?php

/**

 * @package Vendor\People\Domain\Model
 */
class Role extends \TYPO3\CMS\Extbase\DomainObject\AbstractEntity {

    protected $name;

    public function __construct() {
    }

    /**

     * @return void

    public function setName($name) {
        $this->name = $name;
    }

    /**

    public function getName() {

所以问题是我需要在前端访问那些相关的对象（或一个人的角色）。 编辑：我认为我现在对我需要的关系类型有些困惑。 1个人可以扮演n个角色。 无论如何，我以后都不想将人们与角色联系起来。 我只想创建角色，然后再将角色分配给其他人。 因此，我猜这将是1：n的关系。 如果这样的话，那就更容易了。

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;
}
