Question

我在OneToMany连接中有两个连接的实体，但是当我尝试查询它们时，我得到以下错误

注意：未定义的索引：/var/www/Pp/vendor/doctrine/orm/lib/Doctrine/ORM/Query/SqlWalker.php第887行中的Mybox

我的实体如下： Mybox（一）

<?php
namespace Pp\CoreBundle\Entity;

use Doctrine\ORM\Mapping as ORM;

use Gedmo\Mapping\Annotation as Gedmo;

/**

    public static $collectingTypeFixed = 1;
    public static $collectingTypeMinimum = 2;

    /**

    protected $id;

    protected  $PaypalPayment;


    public function __construct(){
        // set default value for paypal with an array.
        $this->PaypalPayment = new \Doctrine\Common\Collections\ArrayCollection();
    }

    /**

    public function removePaypalPayment(\Pp\CreditBundle\Entity\PaypalPayment $paypalPayment)

    public function getPayments() {
        $allPayments = Array();
        foreach ( $this->getPaypalPayment() as $paypalPayment ) {
            $allPayments[] = $paypalPayment;
        }
        return $allPayments;
    }


    /**

     *

    public function setUserId($userId)

        $this->user_id = $userId;

        return $this;
    }

    /**

     *
     * @return integer
     */
    public function getUserId()
    {
        return $this->user_id;
    }
}

PaypalPayment :(很多）

<?php

    protected $id;


    /**

     * @ORM\JoinColumn(name="user_id", referencedColumnName="id")
     */
    protected $user;

    /**

     * @ORM\JoinColumn(name="mybox_id", referencedColumnName="id")
     */
    protected $mybox;


    /**
     * Get id
     *
     * @return integer
     */
    public function getId()
    {
        return $this->id;
    }


    /**

     * @return PaypalPayment
     */
    public function setUser(\Pp\UserBundle\Entity\User $user = null)
    {
        $this->user = $user;

        return $this;
    }

    /**
     * Get user
     *
     * @return \Pp\UserBundle\Entity\User
     */
    public function getUser()
    {
        return $this->user;
    }

    /**

     *
     * @param \Pp\CoreBundle\Entity\Mybox $mybox
     * @return PaypalPayment
     */
    public function setMybox(\Pp\CoreBundle\Entity\Mybox $mybox = null)
    {
        $this->mybox = $mybox;

        return $this;

}

您的错误如下：

你的mappedBy中有一个拼写错误，你写了Mybox而不是mybox
您的OneToMany注释引用了自己

我将反转的部分添加到ManyToOne中，尽管这不是必需的！

/**
 * @ORM\ManyToOne(targetEntity="Pp\CoreBundle\Entity\Mybox", inversedBy="PaypalPayment")
 * @ORM\JoinColumn(name="mybox_id", referencedColumnName="id")
 */
protected $mybox;

/**
 * @ORM\OneToMany(targetEntity="Pp\CoreBundle\Entity\PaypalPayment", mappedBy="mybox")
 */
protected  $PaypalPayment;

Symfony2学说加入OneToMany不起作用
