How do you add a global scope to help sorting records by default in Laravel?

Eloquent

Here is an example of a simple global scope, added to the boot method, that will ensure that a User model is always sorted by first_name:

protected static function boot()
{
  parent::boot();

  static::addGlobalScope('order', function (Builder $builder) {
    $builder->orderBy('first_name');
  });
}
