Question

我想做一个查询来获取模型的关系，并按照查询中的关系对父模型进行排序，如下所示：

 $data = Accommodation::with([  'accommodationRoomsLimited.discount', 'accommodationRoomsLimited', 'accommodationRoomsLimited.roomPricingHistorySearch' => function ($query) use ($from_date, $to_date) {
            $query->whereDate('from_date', '<=', $from_date);
            $query->whereDate('to_date', '>=', $to_date);
        }])->when($bed_count, function ($q, $bed_count) {
            $q->with([
                'accommodationRoomsLimited' => function ($q) use ($bed_count) {
                    $q->where('bed_count', $bed_count);
                }
            ]);

因此，当用户为i发送bed_count 3时，此查询仅显示bed_count为3的房间，如果不显示，则显示住宿，但将空房间作为关系。我想这样我的结果，如果房间没有3的bed_count，它不会自动显示结果的住宿。我该如何实现？谢谢。

也许如果您使用whereHas而不是with，可以这样做：

$data = Accommodation::with([  'accommodationRoomsLimited.discount', 'accommodationRoomsLimited', 'accommodationRoomsLimited.roomPricingHistorySearch' => function ($query) use ($from_date, $to_date) {
        $query->whereDate('from_date', '<=', $from_date);
        $query->whereDate('to_date', '>=', $to_date);
    }])->when($bed_count, function ($q, $bed_count) {
        $q->whereHas('accommodationRoomsLimited', function($query) use ($bed_count) {
            $query->where('bed_count', $bed_count);
        });

更新

if ($bed_count !== null) {
    $data = Accommodation::whereHas('accommodationRoomsLimited', function($query) use ($bed_count) {
        $query->where('bed_count', $bed_count);
    })->with(['accommodationRoomsLimited.discount', 'accommodationRoomsLimited', 'accommodationRoomsLimited.roomPricingHistorySearch' => function ($query) use ($from_date, $to_date) {
        $query->whereDate('from_date', '<=', $from_date);
        $query->whereDate('to_date', '>=', $to_date);
    }])->get();
} else {
    $data = Accommodation::with([  'accommodationRoomsLimited.discount', 'accommodationRoomsLimited', 'accommodationRoomsLimited.roomPricingHistorySearch' => function ($query) use ($from_date, $to_date) {
        $query->whereDate('from_date', '<=', $from_date);
        $query->whereDate('to_date', '>=', $to_date);
    }])->get();
}

希望有帮助。
