I just want to assign a role to newly registered user. How I can achieve this in Laravel 5 with Entrust? I am using Entrust for roles and permissions. Last time I tried to fire event after user registration in a file in vendor folder. Is there any way to fire an event for role assignment without modifying anything inside vendor folder? If yes then where should I fire event? I don't want to modify anything inside my vendor folder like firing event in postRegister() in AuthenticatesAndRegistersUsers.php because new updates will overwrite my code.

Code on this link looks good but i don't know entrust has registration event or not. http://laravel.io/forum/07-02-2014-entrust-assign-role-on-user-signup

Here is my code in routes.php:

// this event is firing on user login and i am getting user object
Event::listen('auth.login', function($user) {
   var_dump($user);
   die(__LINE__);
});

// this event is not firing on user registration
Event::listen('auth.register', function($user) {
   var_dump($user);
   die(__LINE__);
   //	$donor_role = DB::table('app_roles')->where('name', '=', 'donor')->pluck('id');
   //	$user->roles()->attach($donor_role);
   //	return false;
});

Please help me out.
