Symfony Form Error: "Expected argument of type "DoctrineORMQueryBuilder", "DoctrineORMQuery" given"

我在控制器中有两个表单，第一个表单工作正常，但我的第二个表单无法按预期工作。

我的控制器：

// Second Form
$formTwo = $this->get('form.factory')->createNamedBuilder('form2name', new CarType(), null, array())
        ->getForm();
if('POST' === $request->getMethod()) {
if ($request->request->has('form1name')) {
    // handle the first form  
}
if ($request->request->has('form2name')) {
    // handle the second form 
    // get the id value of the selected value. 
  }
}

我的车型：

public function buildForm(FormBuilderInterface $builder, array $options){
   $builder->add('makename','entity',array(
                    'class'=> 'MyTestBundle:Car'CarModel',
                    'query_builder'=>function(EntityRepository $er){
                        return $query = $er->createQueryBuilder('s')
                                    ->select('s.makename')
                                    ->distinct()
                                    ->orderBy('s.makename','ASC');
                }
   ));
  $builder->add('search','submit',array());
}

错误："给定类型为"Doctrine''ORM''
QueryBuilder"、"Doctrine''ORM''Query"的预期参数"

Symfony版本：2.7

在query_builder（用于构建表单）中，您必须返回一个QueryBuilder对象。当前，您返回一个Query对象。

只需删除getQuery()

 $builder->add('makename','entity',array(
                    'class'=> 'MyTestBundle:Car'CarModel',
                    'query_builder'=>function(EntityRepository $er){
                        return $er->createQueryBuilder('s')
                                    ->select('s.makename')
                                    ->distinct()
                                    //->getQuery(); remove this line
                }
