Observe Relationships

This package allows you to configure specific models to trigger update observers for other possible related models. Whilst Laravel does support the touches method, you might be using a package model instance where you cannot define the parent -> child relationship, therefore cannot enable $touches method. This package does the same thing but controlled via configuration.

E.g. A product might relate to a page, but if the page is change the model doesn't re-index currently. This package allows that to work via config and observes.

Installation

composer require parallax/observe-relationships

Configuration

On installation the configuration file should be published to your /config folder. If it is not then run the following:

php artisan vendor:publish --provider=Parallax\ObserveRelationship\ObserveRelationshipProvider

Inside thie /config/observe-relationship.php you will see an empty array of models.

The key is the model you want to watch, then the sub arrays are the models you want to trigger. The required fields for a trigger is model and field. On a save of the watcher instance it will update the updated_at timestamps of the trigger model.

Example

An example configuration of a Page model being watched for a change event that will trigger a Product model to be seen as updated is:

return [
    'models' => [
        \App\Models\Page::class => [
            [
                'model' => \App\Models\Product::class,
                'field' => 'page_id'
            ]
        ]
    ]
];
