Doctrine 2 查询返回的对象没有属性或方法

Question

我正在使用 Doctrine 2 和 Zend Framework 1.11。我已经建立了我的 Doctrine 集成，并且它似乎可以在其中工作，我能够获取并实例化一个实体管理器来使用。但是，我对控制器类中以下行的行为感到困惑：

$transfercurrency = $this->entityManager->getRepository('Gesmoney\Entity\Country')->findBy(array('countrycode' => $transfercountry));

当我执行 var_dump($transfercurrency) 时，我得到一个具有一大堆属性的对象，事实上，它对我来说看起来不正确。我试图把它贴在馅饼上，但它不会让我，因为它超过 100kb。因此，我只粘贴了大约四分之一的enter link description here。同样使用 Netbeans，返回的对象似乎没有属性或方法，因此当我调用代码完成时，我什么也得不到。当我执行 var_dump($transfercurrency[0]->id) 时，出现以下错误；

注意：未定义的属性： Gesmoney\Entity\Country::$property in /shared/www/dev.gesmoneylatest.com/library/Gesmoney/Entity/Country.php 第 55 行 NULL

这是一个相当长的帖子，但我希望有人能回答我的问题。谢谢。

控制器类

<?php

class Systemadmin_ExchangerateController extends Zend_Controller_Action
{
/**
 * @var Bisna\Application\Container\DoctrineContainer
 */
protected $doctrine;

/**
 * @var Doctrine\ORM\EntityManager
 */
protected $entityManager;

public function init()
{
    $this->doctrine = Zend_Registry::get('doctrine');
    $this->entityManager = $this->doctrine->getEntityManager();
}

public function indexAction()
{
    // action body
}


public function getexchangerateAction($transfercountry = 'GB') {

    $this->_helper->layout()->disableLayout();
    $this->_helper->viewRenderer->setNoRender(true);

    $transfercurrency = $this->entityManager->getRepository('Gesmoney\Entity      \Country')->findBy(array('countrycode' => $transfercountry));
    var_dump($transfercurrency);
}

}

实体

<?php

 namespace Gesmoney\Entity;
 /**
 * @Entity @Table(name="countries")
 */
 class Country {
/**
 * @Id @Column(type="integer", length=3, nullable=false) 
 * @GeneratedValue(strategy="IDENTITY")
 * @var integer
 * 
 */
private $id;

/**
 * @Column(type="string", length=25)
 * @var string
 */
private $countryname;

/**
 * @Column(type="datetime")
 * @var string
 */
private $lastupdate;

/**
 * @Column(type="string", length=2)
 * @var string
 */
private $countrycode;

/**
 * @Column(type="string", length=20)
 * @var string
 */
private $countrycurrency;

/**
 * @Column(type="string", length=3)
 * @var string
 */
private $currencycode;


/**
 * @param \Doctrine\Common\Collections\Collection $property
 * @OneToMany(targetEntity="Region", mappedBy="country", cascade={"persist", "remove"})
 */
private $region;


public function __get($property) {
    return $this->property;
}

public function __set($property, $value) {
    $this->property = $value;
}

}

您忘记了__get 和__set 属性上的$

public function __get($property) {
    return $this->$property;
}

public function __set($property, $value) {
    $this->$property = $value;
}
