实体类 + Symfony2 中的 Getter & Setter答案

【问题标题】：Getter & Setter in Entity Class + Symfony2实体类 + Symfony2 中的 Getter & Setter
【发布时间】：2014-02-09 22:57:44
【问题描述】：

我有一个带有表 users 的数据库，其中字段为：user_id, username, password, ... 。我还有一张players 和player_name, player_position 的桌子，...和一个FK user_id。

我使用以下命令从我的数据库中生成了我的实体：

php app/console doctrine:mapping:import --force VolleyScoutBundle xml
php app/console doctrine:mapping:convert annotation ./src
php app/console doctrine:generate:entities VolleyScoutBundle

（没有产生任何错误...）

但在我的用户实体中，我没有属性 player 或 getPlayer() 或 setPlayer()。教义不会产生这个。所以现在我想自己创建它，这样我就可以得到 user_id = user_id 给定的播放器。

我试过这样：

private $player;

/**
 * Get player
 *
 * @return \VolleyScout\VolleyScoutBundle\Entity\Players
 */

public function getPlayer() {
    return $this->player;
}
/**
 * Set player
 *
 * @param \VolleyScout\VolleyScoutBundle\Entity\Players $player
 * @return Users
 */
public function setPlayer(\VolleyScout\VolleyScoutBundle\Entity\Players $player = null){
    $this->player = $player;

    return $this;
}

但是当我尝试 $user->getPlayer 时，我总是得到空值。当用户在玩家表中时也是如此。到目前为止，我的完整用户实体是：

<?php

更新：
我试着添加这个：

 /**
 * @var \VolleyScout\VolleyScoutBundle\Entity\Players
 *
 * @ORM\OneToOne(targetEntity="VolleyScout\VolleyScoutBundle\Entity\Players")
 * @JoinColumn(name="user_id", referencedColumnName="userId")
 */
private $player;

但它什么也没做。为了澄清起见，我的表关系：

更新 2： 在我的用户实体类中，我现在拥有：

    /**
 * @var \VolleyScout\VolleyScoutBundle\Entity\Players
 *
 * @ORM\OneToMany(targetEntity="VolleyScout\VolleyScoutBundle\Entity\Players")
 * @ORM\JoinColumns({
 *   @ORM\JoinColumn(name="user_id", referencedColumnName="user_id")
 * })
 */
private $player;

但是还是不行，现在应该可以了，不是吗？

【问题讨论】：

你确定这个实体甚至是水合的吗？
是的，Players 实体存在。用实体类更新了我的开始帖子。
$players 字段的元数据呢？如果没有，那么教义就不会填充它。也许您只是没有将其包含在 sn-p 中？
元数据是什么？我真的不知道如何使用表外的 FK 而不是表内的 FK 来做到这一点。
docs.doctrine-project.org/en/2.0.x/reference/…，使用这个例子。它是自引用的，但将其更改为 2 个表中的一对多。

【解决方案1】：

从我读到的 cmets 中，您希望在 Users 和 Players 之间建立一对一的关联。您可以像这样将其设置为单向：

class Players
{
    /**
     * @ORM\OneToOne(targetEntity="VolleyScout\VolleyScoutBundle\Entity\Users")
     * @ORM\JoinColumn(name="user_id", referencedColumnName="user_id")
     */
    private $user;

    // ...
}

这意味着您可以从播放器 ($player->getUser()) 访问用户。但由于它是单向的，您将无法从用户 ($user->getPlayer()) 访问播放器。当不在Users 中创建$player 属性时，原则是正确的。

您可以反过来定义关联：

class Users
{
    /**
     * @ORM\OneToOne(targetEntity="VolleyScout\VolleyScoutBundle\Entity\Players")
     * @ORM\JoinColumn(name="player_id", referencedColumnName="player_id")
     */
    private $player;

    // ...
}

您现在可以使用$user->getPlayer()，但不能使用$player->getUser()。

如果两者都需要，则必须将其设置为双向关联：

class Players
{
    /**
     * @ORM\OneToOne(targetEntity="VolleyScout\VolleyScoutBundle\Entity\Users", inversedBy="player")
     * @ORM\JoinColumn(name="user_id", referencedColumnName="user_id")
     */
    private $user;

    // ...
}

class Users
{
    /**
     * @ORM\OneToOne(targetEntity="VolleyScout\VolleyScoutBundle\Entity\Players", mappedBy="user")
     */
    private $player;

    // ...
}

PS：我强烈建议您以单一形式（User 和 Player）命名您的类，而不是复数形式（Users 和 Players），因为这些类的实例（对象）将代表1 个用户或玩家（用户或玩家不多）。

【讨论】：

谢谢，但现在我收到错误消息：在类 'VolleyScout\VolleyScoutBundle\Entity\Users' 上找不到字段 'user' 的映射。
实体Users不应该有字段user（它应该有player），字段user应该在实体Players中。你到底做了什么？
它成功了，谢谢！只需使用我的用户映射将 Entity\Users 更改为 Entity\Players。
啊，我打错了，你已经找到了 :) 我已经编辑了我的答案！
