Symfony的形式與QueryBuilder的參數

我有必要建立一個下拉字段分組數據：Symfony的形式與QueryBuilder的參數

我的形式：

class RetailerDetailFilterType extends AbstractType 
{ 
    public function getActiveRetailerMetrics(): array 
    { 
     return range(25,36); 
    } 

    public function buildForm(FormBuilderInterface $builder, array $options) 
    { 
     $builder->add('month', EntityType::class, 
      [ 
       'class' => 'AppBundle:ConsolidatedOperatorCategoryLowData', 
       'query_builder' => function(ConsolidatedOperatorCategoryLowDataRepository $er){ 
        return $er->getMinMaxByMetricQueryBuilder($this->getActiveRetailerMetrics()); 
       } 
      ]); 

    } 


    public function getBlockPrefix() 
    { 
     return 'key_metric'; 
    } 
}

我的倉庫：

class ConsolidatedOperatorCategoryLowDataRepository extends \Doctrine\ORM\EntityRepository 
{ 
    public function getMinMaxByMetricQueryBuilder($metricRange) 
    { 
     $qb = $this->getEntityManager() 
      ->createQueryBuilder('d'); 
     $qb 
      ->select('d.id, YEAR(d.date) as dyear, MONTH(d.date) as dmonth') 
      ->from('AppBundle:ConsolidatedOperatorCategoryLowData','d') 
      ->where($qb->expr()->in('d.metric_id', $metricRange)) 
      ->groupBy('dyear') 
      ->addGroupBy('dmonth') 
      ->setMaxResults(10) 
      ; 
     return $qb; 

    }

我越來越

您的querybuilder返回的不僅僅是一個實體（dyear，dmonth），我不認爲FormType可以處理它。嘗試用這個替換你的select-call：'select（'d，YEAR（d.date）AS HIDDEN dyear，MONTH（d.date）HIDDEN dmonth'）'。這當然假設你實際上並不需要除了groupBy以外的其他任何地方的dmonth和dyear值。 – ccKep

我認爲它有t o關於Doctrine ORM如何處理關係。當你想通過被引用的對象的id來檢索一個實體時，比如說通過用戶id來查找所有的帖子，那麼你仍然必須將用戶對象傳遞給QueryBuilder，而不僅僅是id。這是因爲教義會解決這些實體之間的聯繫。

看來，metric_id實際上是對某種Metric-entity的引用，只是傳遞一個int數組而不是實際的對象似乎會讓Doctrine的QueryBuilder發生變化。

您可以嘗試將id映射到Metric的新實例，然後改爲傳遞該數組。

另一種解決方案 - 我更喜歡 - 就是使用Native SQL。
