php – laravel Eloquent模型更新事件未被触发

我是Laravel的新手.刚刚有一个初学者的问题,当我尝试使用服务提供者和模型事件来记录更新信息时.

遵循在线文档：https://laravel.com/docs/5.3/eloquent#events

将所有代码放在一起后,我发现模型事件仅在创建使用时触发,但在编辑用户时从不记录任何内容.

我错过了什么吗？感觉$user没有被正确分配.这个从哪里来？来自其他服务提供商？

任何解释或提示将不胜感激！

<?php

namespace AppProviders;

use AppUser;
use IlluminateSupportServiceProvider;

class AppServiceProvider extends ServiceProvider
{
    /**
     * Bootstrap any application services.
     *
     * @return void
     */
    public function boot()
    {
        User::creating(function ($user) {
            Log::info('event creating');
        });

        User::created(function ($user) {
            Log::info('event created');
        });

        User::updating(function ($user) {
            Log::info('event updating');
        });

        User::updated(function ($user) {
            Log::info('event updated');
        });

        User::saving(function ($user) {

        User::saved(function ($user) {
