使用Updator在resetpassword中显示错误

Question

在我的laravel项目中，我在我的用户模型中使用Updater来输入created_by，updated_by和deleted_by.it适用于所有操作，但显示resetpassword的错误。错误

  

Updater.php第13行中的ErrorException：尝试获取属性   非对象

Updater.php

<?php 
namespace App; 
use Auth; 
trait Updater { protected static function boot() { 
        parent::boot(); /* * During a model create Eloquent will also update the updated_at field so * need to have the updated_by field here as well * */ 
        static::creating(function($model) { $model->created_by = Auth::user()->id;
                $model->updated_by = Auth::user()->id;
        });

        static::updating(function($model)  {

                $model->updated_by = Auth::user()->id;
        });
        /*
         * Deleting a model is slightly different than creating or deleting. For
         * deletes we need to save the model first with the deleted_by field
         * */
        static::deleting(function($model)  {

                $model->deleted_by = Auth::user()->id;
                $model->save();

        });
    }
}
