在模型層中（Models）添加三行代碼搞定

use ?Illuminate\Database\Eloquent\SoftDeletes;

use ?SoftDeletes;

protected ?$dates=['delete_at'];

具體用法：

<?php

namespace ?App\Models;

use ?Illuminate\Database\Eloquent\Model;

use ?Illuminate\Database\Eloquent\SoftDeletes;

class ?RelStudentState ?extends ?Model

{

useSoftDeletes;

protected ?$table='rel_student_state';

protected ?$fillable=['student_guid','state'];

protected ?$hidden=['created_at','updated_at','deleted_at'];

protected ?$dates=['delete_at'];

}
