Symfony实体关系无法正常工作

Question

我是Symfony的新手，我正在尝试在实体manyToOne（包含用户数据）和实体User（包含用户应用程序）之间设置Apply关系。用户可以按照他/她想要的次数申请。

在我的User实体中，我有id，我希望将其与user实体中的Apply相匹配

我使用yml格式来实现这个

这是我的User实体

            inversedBy: apply
            joinColumn:
                name: user
                referencedColumnName: id
    lifecycleCallbacks: {  }

现在已经建立了关系，我可以创建一个用户的应用程序，用户id在Apply表中得到很好的存储，所以我猜测关系设置正确。

然而，当我在我的控制器中并尝试获取应用程序时。

$applications = $this->getDoctrine()->getRepository('CoreBundle:Apply')->findAll();

使用dump（）我可以很好地看到应用程序数据，但是User对象都显示为null

不应该显示User Enity的数据吗？我为此疯狂而无法弄清楚我做错了什么。任何帮助将非常感激。

Answer 1

首先，你不需要

protected $userid;

属性和

public function setUserid(\Acme\CoreBundle\Entity\Apply userid = null)
 {
    $this->userid = $userid;

    return $this;
 }
 public function getUserid()
 {
    return $this->userid;
 }

User.php文件中的

方法。 yml文件中的配置看起来没问题。 Apply实体中userId字段的getter和setter方法应如下所示

/**
 * Set user
 *
 * @param Your\NameSpace\User  $user
 */
public function setUserid(Your\NameSpace\User $user = null)
{
    $this->userid = $user;
}

/**
 * Get user
 *
 * @return Your\NameSpace\User 
 */
public function getUserid()
{
    return $this->userid;
}

Answer 2

我最近也注意到Symfony2的这种行为。 我不得不通过运行其中一个getter方法强制对空对象进行初始化。虽然很奇怪。
