Laravel雄辩的查询构建选择最小值

[英]Laravel Eloquent query build select min value

I am having the following query (trimmed) to list the rooms to user for booking: 我正在使用以下查询(已整理)列出要预订的房间供用户使用:

$buildquery=Room::

        with(['hotel' => function ($query) {
            $query->where('status', 0);
        }])

        ->with('image')->with('amenities');

        if ($request->filled('location_id')) {
            $buildquery->Where('city', $request->location_id);
        }

        $buildquery->Where('astatus', 1)->Where('status', 0);

        $rooms = $buildquery->simplePaginate(20);

Actual query (not trimmed): 实际查询(未修剪):

select `rooms`.*, 
(select count(*) from `amenities` inner join `amenities_room` on `amenities`.`id` = `amenities_room`.`amenities_id` where `rooms`.`id` = `amenities_room`.`room_id` and `amenities_id` in (?)) as `amenities_count` 
from 
`rooms` 
where `city` = ? and `price` between ? and ? and `astatus` = ? and `status` = ? having 
`amenities_count` = ? 
limit 21 offset 100

It lists all the rooms available in hotel. 它列出了酒店所有可用的客房。 I need to select only one room for one hotel with least price. 我只需要以最低的价格为一家酒店选择一个房间。

You can use order by 您可以use order by方式use order by

$buildquery->orderBy('COL_NAME', 'DESC')->get();

if you need only one you can use take(1) 如果只需要一个,可以使用take(1)

Hotel::with('room' => function($query) {
    $query->orderBy('price', 'asc')->first();
},
'room.images',
'room.roomTypes',
'room.amenities'])
->get();

You can do something like this to get structure like: 您可以执行以下操作以获得以下结构:

{
    'Hotel': {
        'Room': {
            'Images': {
                //
            },
            'roomTypes': {
                //
            },
            'amenities': {
                //
            }
        }
    }
}

Is that what you want? 那是你要的吗?
