php - Laravel - 试图获取非对象的属性'time_in'

问题描述

我有一个错误

试图获取非对象的属性“time_in”（查看：C:\xampp\htdocs\AttendanceEmployeeSystem\resources\views\admin\attendance.blade.php）

这是我的代码：

考勤控制器.php

<?php

namespace App\Http\Controllers;

use DateTime;
use App\User;
use App\Latetime;
use App\Attendance;
use Illuminate\Support\Facades\Hash;
use App\Http\Requests\AttendanceEmp;


 class AttendanceController extends Controller
{
/**
 * Display a listing of the attendance.
 *
 * @return \Illuminate\Http\Response
 */
public function index()
{
    return view('admin.attendance')->with(['attendances'=> Attendance::all()]);
}

/**
 * Display a listing of the latetime.
 *
 * @return \Illuminate\Http\Response
 */
public function indexLatetime()
{
    return view('admin.latetime')->with(['latetimes' => Latetime::all()]);
}



/**
 * assign attendance to employee.
 *
 * @param  \Illuminate\Http\Request  $request
 * @return \Illuminate\Http\Response
 */
public function assign(AttendanceEmp $request)
{
    $request->validated();

    if ($employee = User::whereEmail(request('email'))->first()){

        if (Hash::check($request->pin_code, $employee->pin_code)) {
                if (!Attendance::whereAttendance_date(date("Y-m-d"))->whereUser_id($employee->id)->first()){
                    $attendance = new Attendance;
                    $attendance->user_id = $employee->id;
                    $attendance->attendance_time = date("H:i:s");
                    $attendance->attendance_date = date("Y-m-d");

                    if (!($employee->schedules->first()->time_in >= $attendance->attendance_time)){
                        $attendance->status = 0;
                    AttendanceController::lateTime($employee);
                    };
                    $attendance->save();

                }else{
                    return redirect()->route('attendance.login')->with('error', 'you assigned your attendance before');
                }
            } else {
            return redirect()->route('attendance.login')->with('error', 'Failed to assign the attendance');
        }
    }



    return redirect()->route('home')->with('success', 'Successful in assign the attendance');
}

/**
 * assign late time for attendace .
 *
 * @return \Illuminate\Http\Response
 */
public static function lateTime(User $employee)
{
    $current_t= new DateTime(date("H:i:s"));
    $start_t= new DateTime($employee->schedules->first()->time_in);
    $difference = $start_t->diff($current_t)->format('%H:%I:%S');


    $latetime = new Latetime;
    $latetime->user_id = $employee->id;
    $latetime->duration   = $difference;
    $latetime->latetime_date  = date("Y-m-d");
    $latetime->save();

}


}

    </div>

 @endsection

我不知道是因为时间格式还是其他原因，请帮忙！

解决方案

当你有这样的事情：

$attendance->user->schedules->first()->time_in

确保链条不会断裂。所以你必须检查是否$attendance->user存在，然后检查是否$attendance->user->schedules存在等等。

现在尝试这样的事情：

 $attendance->user->schedules->first() ? $attendance->user->schedules->first()->time_in : 'Schedule not found';
