在獲取數據時symfony2中的語義錯誤

Question

我正在嘗試編寫一個Web服務以嵌套數組方式獲取該類別下的所有業務。

我得到一個語義錯誤說：

{ 
    code: 500 
    message: "[Semantical Error] line 0, col 14 near 'StreetBumbApiBundle:Buss_owner': Error: Class 'StreetBumb\ApiBundle\Entity\Buss_owner' is not defined." 
} 

我已經在控制器中定義的實體，我不知道爲什麼它顯示此錯誤。

這是我的控制器的功能看起來像：

public function getCategoryAction(){ 

    $em = $this->getDoctrine()->getEntityManager(); 
    $pro = $em->getRepository('StreetBumbApiBundle:Category') 
     ->getBusinessByCategory(); 
    //return $pro; 
    $i = 0; 
    foreach($pro as $p) 
    { 
     $data['category'][$i]['id'] = $p->getId(); 
     $data['category'][$i]['Name'] = $p->getCatName(); 
     //$result[$i] = $p->getId(); 

     $catId = $p->getId(); 

     $business = $em->createQuery('SELECT b FROM StreetBumbApiBundle:Buss_owner b WHERE b.catId = :catId')->setParameter('catId', $catId); 
     $result = $business->getResult(); 
     foreach($result as $r) 
     { 
      $data['business'][$i]['id'][] = $r->getId(); 
     } 
     $i++; 

    } 
    return $data; 
} 

請指導，如果任何人有想法..感謝名單

我相信問題是實體名稱中的下劃線。

Doctrine的命名約定是使用CamelCase，然後將其轉換爲數據庫中的下劃線。由於這種幕後魔法，下劃線會導致實體名稱出現問題。

嘗試更改實體類名稱爲BussOwner並在控制器中調用此名稱。如果您無法更改表名，則可以通過修改實體註釋來處理此問題：

@ORM\Table(name="buss_owner")
