Laravel雄弁とクエリビルダイーガーロード複数の関係where句

Question

私は、彼らがroom_types、部屋、料金、私は価格と料金で部屋や料金と

room_typesを取得したい価格（価格room_type_idあり、いくつかのテーブルを持っています= room_types.id）。私はその

 $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(); 

ような何かをしようとしましたが、この例では、イムは、すべての価格を取得しますが、私はroom_type_id価格が現在のroom_type.idに等しいことのみを取得したいです。だから私はこのような考えをしようとしました

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

しかし、私はどこにclouseを入れるべきかわかりません。だからこれを行う方法はありますか？ そして、私は持ちたいという結果が
