Observers

Introduction

Observers in the Streams Platform piggy back on Laravel's Observers. This documentation will assume you are already familiar with Laravel observers.

Laravel Observers

Defining Observers

Eloquent model observers can be created as shown below.

<?php namespace Anomaly\ExampleTheme\Example;

use Anomaly\Streams\Platform\Model\EloquentModel;
use Anomaly\Streams\Platform\Model\EloquentObserver;

class ExampleObserver extends EloquentObserver
{
    //
}

Registering Observers

You can register observers inside the register or boot method of a service provider.

Service Providers

<?php namespace Anomaly\ExampleModule;

use Anomaly\ExampleModule\Example\ExampleModel;
use Anomaly\ExampleModule\Example\ExampleObserver;

use Anomaly\Streams\Platform\Addon\AddonServiceProvider;

class ExampleModuleServiceProvider extends AddonServiceProvider
{
    public function register()
    {
        //
    }

    public function boot()
    {
        ExampleModel::observe(ExampleObserver::class);
    }

}

Events

All model observers support the following model events.

public function creating(EloquentModel $model)
{
    // Do stuff.

    parent::creating($model);
