我正在尝试通过Laravel和Carbon来计算以分钟为单位的时差。
我的查询：$findPauseWorky = ClockingSystemHours::where('total_time','=', null)->where('worky_id','=',$id)->whereNotNull('end_time')->get();
从查询中获取集合时，结果如下：
Collection {#407
#items: array:1 [
0 => ClockingSystemHours {#408
#dates: array:3 [
0 => "start_time"
1 => "end_time"
2 => "total_time"
]
#original: array:8 [
"id" => 2
"start_time" => "16:21:29"
"end_time" => "23:20:52"
"total_time" => null
"worky_id" => 2
"employee_id" => 1
"created_at" => "2019-01-24 16:21:29"
"updated_at" => "2019-01-24 16:21:29"
]
您会在结果中看到，我已经在模型中设置了$dates。
如果我执行此dd($findPauseWorky->first()->start_time);，则会导致以下结果：
Unexpected data found.
↵Unexpected data found.
↵Data missing
当我执行以下操作时：dd($findPauseWorky->first()->worky_id);会导致以下结果：
2
我在做什么错？还是我无法访问数据的原因？
