There are two data admins and members in roles table, I would like to know to to filter users which role is admins.

Answer 1

This should give you all users who are admins.

$users = User::whereHas('roles', function($q) {
    $q->where('name', '=', 'admins');
})->get();

You can see more information on the has() method at http://laravel.com/docs/eloquent#querying-relations
