Symfony2的學說加入一對多不工作

Question

我在一對多連接的兩個連接實體，但是當我試圖讓查詢出來，我收到以下錯誤

注意：未定義指數：myBox上在/ var/WWW/PP /供應商/教義/ ORM/LIB /學說/ ORM /查詢/ SqlWalker.php線887

我的實體是如下所示： myBox上（一個）

<?php

     $this->PaypalPayment = new \Doctrine\Common\Collections\ArrayCollection();

     return $allPayments; 
    }

    */ 
    public function getUserId() 
    {

PaypalPayment：（很多）

    protected $id; 


    /**

    protected $user; 

    /**

    protected $mybox; 


    /**

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


    /**

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

     return $this; 
    } 

    /**

    */ 
    public function getUser() 
    {

    } 

    /**

} 

Answer 1

你的錯誤有以下幾條：

1. 你在你的mappedBy有一個錯字，你寫Mybox，而不是mybox
2. 你OneToMany註釋引用本身

我將inversedBy部分加入了ManyToOne，但是沒有必要！

/** 
* @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;
