我有3个型号 住所 住宿 roomPricingHistory 我正在通过我的酒店模型对选择该用户的每个用户进行查询，以选择每个房间的最低价格，然后返回该价格，我想从所有房间中选择价格最低的房间，这是我现在的查询：
$data = Accommodation::with(['city','accommodationRoomsLimited.roomPricingHistorySearch' =>function($query) use($from_date,$to_date){
$query->whereDate('from_date', '<=', $from_date);
$query->whereDate('to_date', '>=', $to_date);
// here is where i want to pick the lowest price room and actually do a query on accommodationRoomsLimited based on roompricinghistorysearch result
}])
->whereIn('city_id',$city_id)
->whereIn('grade_stars',$stars)
->orWhere('accommodation_type_id',$type_id)
->get();
这是我在api中当前查询的结果输出：

您是否尝试过下面的查询显示
<?php
$data = Accommodation::with(['city', 'accommodationRoomsLimited.roomPricingHistorySearch' => function($query) use($from_date,$to_date) {
$query->whereDate('from_date', '<=', $from_date);
$query->whereDate('to_date', '>=', $to_date);
$query->OrderBy('sales_price' , 'ASC');
$query->limit(1);
}])
->whereIn('city_id',$city_id)
->whereIn('grade_stars',$stars)
->orWhere('accommodation_type_id',$type_id)
->get();
