在Laravel中创建，更新或删除任何模型后采取措施

本文介绍了在Laravel中创建，更新或删除任何模型后采取措施的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我想在我的应用程序中每次创建，更新或删除任何模型时都执行一个函数.

I want to execute a function every time ANY model is created, updated, or deleted in my application.

例如，我想将模型名称及其记录数据打印到我的日志中.

For example, I want to print the model name and its record data to my log.

我该怎么做?我一直在寻找可以扩展的课程，但是没有任何运气.

How can I do this? I've been looking for some class to extend, but haven't had any luck.

推荐答案

对Robok答案的评论，您可以使用 BaseObserver .

Answering to your comment on Robok's answer, you can have a BaseObserver.

例如，这是我使用的一个:

As example, here is the one I use:

<?php namespace App\Observers; use Illuminate\Database\Eloquent\Model as Eloquent; class BaseObserver { public function saving(Eloquent $model) {} public function saved(Eloquent $model) {} public function updating(Eloquent $model) {} public function updated(Eloquent $model) {} public function creating(Eloquent $model) {} public function created(Eloquent $model) {} public function deleting(Eloquent $model) {} public function deleted(Eloquent $model) {} public function restoring(Eloquent $model) {} public function restored(Eloquent $model) {} }

现在任何模型观察者都可以扩展它:

Now any model observer can extend it:

<?php namespace App\Observers; use App\Observers\BaseObserver; class ProductObserver extends BaseObserver { public function creating(Eloquent $model) { $model->author_id = Sentry::getUser()->id; } public function created(Eloquent $model) { if(Input::hasFile('logo')) Image::make(Input::file('logo')->getRealPath())->save(public_path() ."/gfx/product/logo_{$model->id}.png"); } public function updating(Eloquent $model) { $model->author_id = Sentry::getUser()->id; } public function updated(Eloquent $model) { if(Input::has('payment_types')) $model->paymentTypes()->attach(Input::get('payment_types')); //Upload logo $this->created($model); } }

如果您想在每个观察者中使用类似 $ model-> author_id = Sentry :: getUser()-> id 之类的东西，那么您当然可以在 BaseObserver中应用它.

If you want to have something like $model->author_id = Sentry::getUser()->id in every observer, you can of course apply that in the BaseObserver.
