學說2查詢返回的對象沒有屬性或方法

Question

我正在使用Doctrine 2和Zend Framework 1.11。我已經建立了我的學說集成體系，並且它在接下來的工作中，我能夠獲得實例經理的實例並與之合作。但是，我通過在控制器類以下行的行爲感到困惑：

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

當我做的var_dump（$ transfercurrency），我得到了一大堆屬性的對象，事實上，這不是」你看我是對的。我試圖將它張貼在pastie上，但它不會讓我因爲它超過100kb。因此，我只是粘貼了大約四分之一enter link description here。同樣使用Netbeans，似乎沒有返回對象的屬性或方法，因此當我調用代碼完成時，我什麼也得不到。當我做var_dump（$ transfercurrency [0] - > id）時，我得到以下錯誤;

公告：未定義的屬性： Gesmoney \實體\國家::在線55 NULL在 /shared/www/dev.gesmoneylatest.com/library/Gesmoney/Entity/Country.php $財產

這是一個相當長的帖子，但我希望有人對我的問題有答案。謝謝。

Controller類

<?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); 
} 

} 

實體

<?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; 
} 

}

你忘了你的屬性$爲__get和__set

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

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