当我将文件上传到服务器时，我遇到了这个问题。
Error: Class Prizes\PrizesBundle\Entity\Category has no field or association named order_cat
我的类别类：

这就是我构建表单的方式
public function buildForm( FormBuilder $builder, array $options )
{
$query = new QueryBuilder( $this->em);
$query->addSelect( 's' )->from( Status::getFQCN( ), 's' )->join( 's.status_entity', 'se' )->where( "se.name = 'Prize'" );
$builder->add( 'status', 'entity', array ( 'class' => 'AppStatusBundle:Status', 'property' => 'name', 'query_builder' => $query, "required" => false, 'empty_value' => ' - SELECT - ') );
$builder->add( 'name', 'text', array ( "required" => false) );
$builder->add( 'country', 'entity',array ('class' => 'CSCBundle:SystemCountry', 'property' => 'country.name', "required" => false, 'empty_value' => ' - SELECT - ') );
$builder->add( 'category', 'entity', array ('class' => 'PrizesBundle:Category', 'property' => 'name', "required" => false, 'empty_value' => ' - SELECT - ', 'query_builder' =>
function(EntityRepository $er) {
return $er->createQueryBuilder('c')->join( 'c.status', 's' )->where( "s.name = 'Alive'")
->orderBy('c.order_cat', 'ASC');
},) );
$builder->add('brand', 'entity', array ( 'class' => 'PrizesBundle:Brand', 'property' => 'name', "required" => false, 'empty_value' => ' - SELECT - ') );
}
我曾经有
return "SELECT cat FROM " . Category::getFQCN( ) . " cat
WHERE cat.status = 1 ORDER BY cat.order_cat"
而不是这个
SELECT cat FROM " . Category::getFQCN( ) . " cat
WHERE cat.status = 1
但是当我尝试时，我得到[Semantical Error] line 0, col 108 near 'order_cat AS': Error: Class Prizes\PrizesBundle\Entity\Category has no field or association named order_cat
我究竟做错了什么？我怎样才能解决这个问题？我已经删除了缓存并验证了文件。
编辑：我需要两个错误的答案。
