Best way to check permissions with sentry 2 at Laravel - php

Question

Im developing a basic aplication core, first im working with user/groups and & permissions access.
I choose Sentry 2 to work, and i want to limit the access to my.domain/admin to a users or groups that have admin permissions.
Im developing a filter to check if the user is admin and if hasAccess to a specific action, like users.index, or users.custom_fuction.
In my routes i have:
/**
* ADMIN ROUTES
*/
Route::group(array('before' => 'sentry'), function() {
Route::group(array('before' => 'admin'), function() {
Route::group(array('prefix' => 'admin'), function()
{
Route::get('/', function()
{
return View::make('admin');
});
Route::resource('groups', 'GroupController',
array('except' => array('show')));
Route::resource('users', 'UserController',
array('except' => array('show')));
Route::get('users/{id}/groups', 'UserController#groups');
Route::post('users/{id}/groups', 'UserController#store_groups');
Route::get('{table}/{id}/permissions',
'PermissionController#manage_entity');
Route::post('{table}/{id}/permissions',
'PermissionController#update_permissions');
});
});
});
The sentry filter only checks if is loged and rediret to login page, the admin filter is:
/*
* Sentry admin & hasAccess filter
*/
Route::filter('admin', function()
{
$user = Sentry::getUser();
if (!$user->hasAccess('admin')) return Redirect::to('/');
// Ask if user hasAccess to specific action
var_dump(Route::getCurrentRoute()->getPath());
var_dump(Route::getCurrentRoute()->getAction());
});
I have to make another check with the actual route, in the getAction array there are a
'as' => string 'admin.users.index' (length=17)
I can use that for Route::resource i define but, how i did for other functions like groups or permissions.
Maybe there is a better way to handle that, but i dont know it.
Thanks in advice.

I found the solution:
http://laravel.com/docs/routing#named-routes
And now i have:
Route::get('users/{id}/groups', array('as' => 'admin.users.groups', 'uses' => 'UserController#groups'));
Route::post('users/{id}/groups', 'UserController#store_groups');
Route::get('{table}/{id}/permissions', array('as' => 'admin.permissions.manage_entity', 'uses' => 'PermissionController#manage_entity'));
Route::post('{table}/{id}/permissions', 'PermissionController#update_permissions');
And the filters looks like:
Route::filter('admin', function()
{
$user = Sentry::getUser();
$action = Route::getCurrentRoute()->getAction();
if (!$user->hasAccess($action['as'])) return Redirect::to('/admin');
});
But now, all route inside that filter need a as declared or error will popup.
Hope this helps others.
