【问题描述】：

我是 symfony2 的新手。我创建了一个称为投资组合控制器的基本控制器和该控制器的一些索引视图。我也创建了一个实体类，但它给出了错误。

我的控制器是

<?php
namespace IDP\Bundle\Controller;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
 class PortfolioController extends Controller {

    public function indexAction() {
     $product = $this->getDoctrine()
      ->getRepository('IDPBundle:Portfolio')
      ->find(1);
    return $this->render('IDPBundle:Portfolio:index.html.twig');
   }

}

在 src/IDP/Bundle/Entity/Portfolio.php 里面

 <?php
 namespace IDP\Bundle\Entity;
 use Doctrine\ORM\Mapping as ORM;
 use Symfony\Component\Validator\Constraints as Assert;
 class Portfolio
 {
   private $id;
   private $user_id;
   private $portfolio_name;
   private $description;
   private $permalink;
   private $sharingCode;
   private $shared;
   private $shared_portfolio_calls;
   private $patentgroup_id;

public function __construct()
{
    $this->portfolioGroups = new \Doctrine\Common\Collections\ArrayCollection();
}
public function getId()
{
    return $this->id;
}
public function setName($portfolio_name)
{
    $this->name = $portfolio_name;
}
public function setDescription($description)
{
    $this->description = $description;
}
public function getDescription()
{
    return $this->description;
}
public function setSharingCode($sharingCode)
{
    $this->sharingCode = $sharingCode;
}
public function getSharingCode()
{
    return $this->sharingCode;
}
public function setShared($shared)
{
    $this->shared = $shared;
}
public function getShared()
{
    return $this->shared;
}
public function getUser()
{
    return $this->user;
}
}

我的表格名称是 pm_portfolios，它包含我在投资组合类中提到的所有字段。

谁能告诉我我做错了什么？

【解决方案1】：

您的实体缺少所有 ORM 元数据，例如类本身的 @ORM\Entity 和其属性的其他元数据。见the example from the docs。

【解决方案2】：

您的实体类没有任何 ORM 元数据。试试这样的

 <?php

namespace IDP\Bundle\Entity;

 use Doctrine\ORM\Mapping as ORM;
 use Symfony\Component\Validator\Constraints as Assert;
 /**
 * IDP\Bundle\Entity\Portfolio
 * @ORM\Table(name="pm_portfolios")
 */
class Portfolio
{
/**
 * @var integer $id
 */
private $id;

/**
 * @var integer $user_id
 */
private $user_id;

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

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

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

/**

 */
private $sharing_code;

/**

 */
private $shared;

/**

private $shared_portfolio_calls;

/**

 */
private $patentgroup_id;


/**

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

/**

public function setUserId($userId)
{
    $this->user_id = $userId;

    return $this->user_id;
}

/**

public function getPortfolioName()
{
    return $this->portfolio_name;
}

/**

public function setDescription($description)
{
    $this->description = $description;
}

/**

 */
public function getDescription()
{
    return $this->description;
}

/**

 *

 */
public function setPermalink($permalink)
{
    $this->permalink = $permalink;
}

/**

{
    return $this->permalink;

{
    $this->sharing_code = $sharingCode;
}

public function getSharingCode()
{
    return $this->sharing_code;
}

/**

 */
public function setShared($shared)
{
    $this->shared = $shared;
}

/**
 * Get shared
 *
 * @return boolean 
 */
public function getShared()
{
    return $this->shared;
}

/**
 * Set shared_portfolio_calls
 *
 * @param integer $sharedPortfolioCalls
 */
public function setSharedPortfolioCalls($sharedPortfolioCalls)
{
    $this->shared_portfolio_calls = $sharedPortfolioCalls;
}

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

/**
 * Set patentgroup_id
 *
 * @param integer $patentgroupId
 */
public function setPatentgroupId($patentgroupId)
{
    $this->patentgroup_id = $patentgroupId;
}

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

}
