Extending User Models

Laravel's authorization features are available in models which implement the Illuminate\Foundation\Auth\Access\Authorizable trait.

By default Laravel does this in \App\User by extending Illuminate\Foundation\Auth\User, in which the trait and Illuminate\Contracts\Auth\Access\Authorizable contract are declared.

If you are creating your own User models and wish Authorization features to be available, you need to implement Illuminate\Contracts\Auth\Access\Authorizable in one of those ways as well.

Extending Role and Permission Models

If you are extending or replacing the role/permission models, you will need to specify your new models in this package's config/permission.php file.

First be sure that you've published the configuration file (see the Installation instructions), and edit it to update the models.role and models.permission values to point to your new models.

Note the following requirements when extending/replacing the models:

Extending

If you need to EXTEND the existing Role or Permission models note that:

• Your Role model needs to extend the Spatie\Permission\Models\Role model
• Your Permission model needs to extend the Spatie\Permission\Models\Permission model

Replacing

If you need to REPLACE the existing Role or Permission models you need to keep the following things in mind:

• Your Role model needs to implement the Spatie\Permission\Contracts\Role contract
• Your Permission model needs to implement the Spatie\Permission\Contracts\Permission contract

Migrations - Adding fields to your models

You can add your own migrations to make changes to the role/permission tables, as you would for adding/changing fields in any other tables in your Laravel project. Following that, you can add any necessary logic for interacting with those fields into your custom/extended Models.
