Symfony2：錯誤「屬性已被聲明，但必須聲明一次」

Question

由於我是Symfony的新手，我嘗試使用Doctrine創建實體關係。我收到錯誤「[bundle/entity/file_location」中的屬性「report」已經聲明，但必須聲明一次「當我嘗試更新架構時

我遵循Symfony文檔，但無法找到解決方案。

實體/ Report.php

<?php 

namespace Aurora\ReportBundle\Entity; 

use Doctrine\ORM\Mapping as ORM; 
use Doctrine\Common\Collections\ArrayCollection; 

/**

    /** 
    * @var integer 
    */ 
    private $id; 
/** 
* @var string 
*/ 
private $name; 

/** 
* @var string 
*/ 
private $description; 

/** 
* var array 
*/ 
private $reportFiles; 


public function _construct() { 
    $this->reportFiles = new ArrayCollection(); 
} 
/** 
* Get id 
* 
* @return integer 
*/ 
public function getId() 
{ 
    return $this->id; 
} 

/**

    $this->name = $name; 

    return $this;

     return $this;

Answer 1

教義，你應該不申報關係的列字段。

從Doctrine/ReportFile.orm.yml刪除report字段，但留下manytoOne關係。學說將自行創建列。
