（ZF2 + Doctrine2）Find，FindBy不會返回任何結果或錯誤消息

Question

我正在使用ZF2 + Doctrine2的一個小項目。 我有蒙山下面的描述中學說實體：

    } 

    public function setEstEmprunter($estEmprunter) 
    { 
     $this->estEmprunter = $estEmprunter; 
    } 




} 

並與下面的代碼庫：

<?php 
namespace Akplanu\Repository; 

use Akplanu\Entity\Exemplaire; 

use Doctrine\ORM\EntityRepository; 

class ExemplaireRepository extends EntityRepository 
{ 

    /** 
    * add or update an exemplaire 
    */ 
    public function save(Exemplaire $exemplaire) 
    { 
     $this->getEntityManager()->persist($exemplaire); 
     $this->getEntityManager()->flush(); 
    } 

    /** 
    * delete a list exemplaire base on ids array 
    */ 
    public function delete($idsExemplaire) 
    { 
     $dql = "DELETE FROM Akplanu\Entity\Exemplaire d WHERE d.id IN (:idsExemplaire)"; 
     $query = $this->getEntityManager()->createQuery($dql); 
     $query->setParameter('idsExemplaire',$idsExemplaire); 
     $query->execute(); 
    } 

    /** 
    * find Exemplaire by id 
    */ 
    public function findById($id) 
    { 
     return $this->find((int)$id);     
    } 

    /** 
    * find exemplaire by name 
    */ 
    public function findByNumeroEntree($numeroEntree) 
    { 
     return $this->findBy(array('numeroEntree'=>$numeroEntree),array('numeroEntree'=>'asc')); 
    } 

    /** 
    * retrieve list of all exemplaire 
    */ 
    public function getAll() 
    { 
     return $this->findAll(); 
    } 

    public function getListExemplairesPouvantEtreEmprunter() 
    { 
     $dql = "SELECT e,l FROM Akplanu\Entity\Exemplaire e 
       JOIN e.livre l 
       WITH e.estEmprunter = false"; 
     $query = $this->getEntityManager()->createQuery($dql); 
     return $query->getResult(); 
    } 
} 

?> 

當我通過我在控制器上的服務調用ExemplaireRepository :: findById（）方法（通過使用AJAX請求），請求不返回任何結果，即使我編輯方法如下：

/** 
* find Exemplaire by id 
*/ 
public function findById($id) 
{ 

    $dql = "SELECT e,l,d,o,t FROM Akplanu\Entity\Exemplaire e 
      JOIN e.livre l 
      JOIN e.donateur d 
      JOIN e.origine o 
      JOIN e.etat t 
      WHERE e.id=:id"; 
    $query = $this->getEntityManager()->createQuery($dql); 
    $query->setParameter('id', $id); 
    return $query->getResult(); 

} 

在螢火控制檯我有一個wainting IC在比沒有任何錯誤消息無限期顯示，但ExemplaireRepository :: getListExemplairesPouvantEtreEmprunter（）運行良好！

有人已經面對這樣的問題嗎？它可能導致哪裏？我該如何解決它。 預先感謝您。

Answer 1

這很可能是代碼中的設置錯誤。我會建議使用學說模塊Zend框架2.

https://github.com/doctrine/DoctrineModule

的自述文件解釋瞭如何使用作曲家安裝模塊。
