保存后，保存前等的laravel模型回调 [英] laravel model callbacks after save, before save, etc

问题描述

Laravel中是否存在回调，如:

Are there callbacks in Laravel like:

afterSave()
beforeSave()
etc

我搜索了但什么都没找到.如果没有这样的东西-实施它的最佳方法是什么?

I searched but found nothing. If there are no such things - what is best way to implement it?

谢谢！

推荐答案

实际上，Laravel在保存|更新|创建某些模型之前|之后具有真正的回调.检查一下:

Actually, Laravel has real callback before|after save|update|create some model. check this:

https://github.com/laravel/laravel/blob/3.0/laravel/database/eloquent/model.php#L362

保存和保存的EventListener都是真正的回调

the EventListener like saved and saving are the real callbacks

$this->fire_event('saving'); 

$this->fire_event('saved');

我们该如何处理?只需将其分配给此eventListener示例:

how can we work with that? just assign it to this eventListener example:

 \Laravel\Event::listen('eloquent.saving: User', function($user){
  $user->saving();//your event or model function
});
