OneToMany 无效映射

Question

我正在尝试创建 oneToMany 关系。由于 Doctrine 仅提供 ManyToOne 单向 im 使用它。不知何故，映射验证失败，我无法发现我的错误：

验证错误：

[映射] 失败 - 实体类 'Strego\TippBundle\Entity\BetRound' 映射无效： * 关联 Strego\TippBundle\Entity\BetRound#userStatus 指的是拥有方字段 Strego\TippBundle\Entity\UserBetRoundStatus#betRound 没有 存在。

我的第一个实体（BetRound）：

<?php 
namespace Strego\TippBundle\Entity;

use Doctrine\ORM\Mapping as ORM;

use Doctrine\Common\Collections\Collection as Collection;
use Strego\AppBundle\Entity\Base as BaseEntity;


/**
 * Strego\TippBundle\Entity\BetRound
 *
 * @ORM\Table()
 * @ORM\Entity
 */
class BetRound extends BaseEntity {

    //......

    /**
     *
     * @var Collection
     * @ORM\OneToMany(targetEntity="UserBetRoundStatus", mappedBy="betRound", cascade={"all"})
     */
    protected $userStatus;

}

我的相关实体（UserBetRoundStatus）

<?php
namespace Strego\TippBundle\Entity;

use Doctrine\ORM\Mapping as ORM;
use Symfony\Component\Validator\Constraints as Assert;
use Strego\AppBundle\Entity\Base as BaseEntity;

/**
 * Strego\TippBundle\Entity\Game
 *
 * @ORM\Table
 * @ORM\Entity
 * @UniqueEntity(fields={"user", "betRound"}, message="Unique Entity Validator Fails for UserStatus", groups="unique")
 * 
 */
class UserBetRoundStatus extends BaseEntity {
    // .....

    /*
     * @var BetRound
     * @ORM\ManyToOne(targetEntity="BetRound", inversedBy="userStatus")
     * @ORM\JoinColumn(name="betround_id", referencedColumnName="id", nullable=false)
     * @Assert\NotNull()
     */
    protected $betRound;
}

我找到了问题：

/**  <---------  you need two *
 * @var BetRound
 * @ORM\ManyToOne(targetEntity="BetRound", inversedBy="userStatus")
 * @ORM\JoinColumn(name="betround_id", referencedColumnName="id", nullable=false)
 * @Assert\NotNull()
 */
protected $betRound;
