實體類有沒有現場或協會在我的數據庫命名爲喜歡

Question

我想創建，根據e.rules_id恢復了一些的請求，e.status_id

public function findStat() 
{ 
$types = $this->em 
     ->getRepository('EthanRestBundle:EthanRules') 
     ->createQueryBuilder('e') 
     ->select('e.rules_id, e.status_id, COUNT(*)') 
     ->groupBy('e.rules_id, e.status_id') 
     ->orderBy('rules_id'); 

    $types = $types->getQuery()->getSingleScalarResult(); 

    return $types; 

} 

錯誤消息：

[Semantical Error] line 0, col 9 near 'rules_id, e.status_id,': Error: Class Ethan\RestBundle\Entity\EthanRules has no field or association named rules_id"

我制定的Symfony 2 FosrestBundle默認名稱與在實體類，但with_underscores在數據庫中創建首字母大寫一個REST應用

Answer 1

主義各個領域。

您需要相應地將您的rules_id和status_id更改爲rules和status。

Answer 3

因爲我們還沒有定義的屬性$rules_id主義不能選擇一個。相反，加入兩個實體，並選擇其ID：

$types = $this->em 
    ->getRepository('EthanRestBundle:EthanRules') 
    ->createQueryBuilder('e') 
    ->select('r.id AS rule_id, s.id AS status_id, COUNT(DISTINCT e.id)') 
    ->leftJoin('e.rules', 'r') 
    ->leftJoin('e.status', 's') 
    ->groupBy('r.id, s.id') 
    ->orderBy('r.id'); 

但是：您使用getSingleScalarResult()將不能與多個結果行工作！ 顯然getArrayResult()將是您的最佳選擇，因爲它看起來像你不想處理對象。
