Laravel 从嵌套关系中提取一个数组

Question

我只需要获取 roomnumber从以下查询返回的数组:

$roomnumbers = Room::with(['floorroomcount' => function($query){
                $query->with('roomnumber')->get();
        }])->where('roomtype_id', $roomtype_id)->get();

尝试:
关注采摘回来了 floorroomcount

$roomnumbers->pluck('floorroomcount');

但我需要 roomnumber数组，我怎样才能得到？

Answer 1

这给你所有roomnumber结果是一个集合:

$roomnumbers->pluck('floorroomcount')->collapse()->pluck('roomnumber')->collapse();
