Laravel - Некоторые поля сохраняют ноль в базе данных в моем Laravel проекте

Question

Я получил некоторые данные из jQuery в Laravel -5.8:

Класс модели:

class HrLeaveRequest extends Model
{
   protected $table = 'hr_leave_requests';

   protected $primaryKey = 'id';
   protected $fillable = [
              'id',
              'company_id',
              'employee_id',
              'reason',
              'leave_type_id',
              'commencement_date',
              'resumption_date',
              'authorized_days',
              'available_days',
              'leave_status',
              'no_of_days',
              'relief_officer_id',
              'contact_person_fullname',
              'contact_person_phone',
              'contact_person_address',
              'created_by',
              'created_at',
              'updated_by',
              'updated_at',
              'is_active'
          ];
   protected $dates = [];
   protected $casts = [];

   public function reliefofficer()
   {
      return $this->belongsTo('App\Models\Hr\HrEmployee','relief_officer_id');
   }    

   public function leavetype()
   {
      return $this->belongsTo('App\Models\Hr\HrLeaveType','leave_type_id');
   }
}

Контроллер

public function store(StoreLeaveRequestRequest $request)
{
        $leaverequest = HrLeaveRequest::create([
            'leave_type_id'             => $request->leave_type_id,
            'employee_id'               => $userEmployee,
            'commencement_date'         => $commencementDate,
            'resumption_date'           => $resumptionDate,  
            'authorized_days'           => $request->authorized_days,
            'available_days'            => $request->available_days,
            'no_of_days'                => $days,
            'reason'                    => $request->reason,
            'relief_officer_id'         => $request->relief_officer_id,
            'contact_person_fullname'   => $request->contact_person_fullname,
            'contact_person_phone'      => $request->contact_person_phone,
            'contact_person_address'    => $request->contact_person_address,
            'company_id'        => Auth::user()->company_id,
            'created_by'        => Auth::user()->id,
            'created_at'        => date("Y-m-d H:i:s"),
            'is_active'         => 1,
        ]);   
        Session::flash('success', 'Leave Request is created successfully');
        return redirect()->route('service.leave_requests.index');              
}



    <script type="text/javascript">
    $(document).ready(function() {
        $(document).on('change', '#leave_type', function() {
            var air_id =  $(this).val();

            var a = $(this).parent();

            var op = "";

            $.ajax({
                type: 'get',
                url: '{{ route('get.leavecounts.all') }}',
                data: { 'id': air_id },
                dataType: 'json',      //return data will be json

                success: function(data) {
                    $('#authorized_leave_days').val(data.authorizedleavedays);
                    $('#available_leave_daysx').val(data.availableleavedays);

                     let sumAvailableDays = parseInt(data.authorizedleavedays) - parseInt(data.availableleavedays);

                    $("#available_leave_days").val(sumAvailableDays);
                },
                error:function(){

                }
            });
        });
    });
    </script>

Я получил 'authorized_days 'and' available_days 'из jQuery выше и загрузили результат в:

И я четко вижу данные на своем экране, но когда я их сохранил, в каждом из полей я обнаружил ноль.

Затем я сделал:

дд ($ Leaverequest);

, и у меня есть это:

дд ($ Leaverequest):

  #attributes: array:17 [▼
    "leave_type_id" => "1"
    "employee_id" => 2
    "commencement_date" => Carbon\Carbon @1586559600 {#804 ▶}
    "resumption_date" => Carbon\Carbon @1587769200 {#790 ▶}
    "authorized_days" => null
    "available_days" => null
    "no_of_days" => 11
    "relief_officer_id" => "10"
    "contact_person_fullname" => "assasasaddddd"
    "contact_person_phone" => "08099448844"
    "contact_person_address" => "xxzxzxzxz ddds"
    "company_id" => 1
    "created_by" => 2
    "created_at" => "2020-04-10 22:10:41"
    "is_active" => 1
    "id" => 9
  ]

Вы видите:

    "authorized_days" => null
    "available_days" => null

Как мне решить эту проблему?

Спасибо
