Question

나는 그들이 room_types, 객실, 요금, 나는 가격 요금 객실 및 요금과

room_types을 얻으려면 가격 (가격 room_type_id 있으며, 몇 테이블이 = room_types.id). 나는 모든 가격을 받고 임 그

 $roomTypeIds = []; 

     foreach ($hotel->rooms as $room) { 
      array_push($roomTypeIds, $room->roomtype->id); 
     } 

     $roomsByType = RoomType::with(['rooms' => function ($query) { 
      $query->with(['rates' => function($q) { 
       $q->with('policy', 'prices'); 
      }]); 
     }])->whereIn('id', array_unique($roomTypeIds))->get(); 

좋아하지만이 예에서 뭔가를 시도했지만 나는 room_type_id 현재 room_type.id 같다에만 가격하는 것을 싶어. 그래서 그것을 위해 몇 가지 시도를하려고했습니다.

 $roomsByType = RoomType::with(['rooms' => function ($query) { 
      $query->with(['rates' => function($q) { 
       $q->with(['policy', 'prices' => function($q1) { 
        $q1->where('room_type_id', ''); 
       }]); 
      }]); 
     }])->whereIn('id', array_unique($roomTypeIds))->get(); 

하지만 어디서 clouse를 넣어야할지 모르겠군요. 이렇게 할 방법이 있습니까? 내가 갖고 싶어한다는 결과가
