【问题描述】：
我有几张桌子，它们是 room_types、房间、价格、价格我想要得到的
room_types 房间的价格和价格的价格 where(price room_type_id = room_types.id) 。我试图做类似的事情
$roomTypeIds = [];
foreach ($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();
但在此示例中，我获取所有价格，但我只想获取 room_type_id 等于当前 room_type.id 的价格。因此，为此我尝试了一些这样的想法
$roomsByType = RoomType::with(['rooms' => function ($query) {
$query->with(['rates' => function($q) {
$q->with(['policy', 'prices' => function($q1) {
$q1->where('room_type_id', '');
}]);
}]);
}])->whereIn('id', array_unique($roomTypeIds))->get();
但我不知道该放在哪里 clouse。那么有没有办法做到这一点？ 我想要的结果是
