php - Symfony2 add role after registration to user account using event_subscriber and FOSUser bundle -

working on first large symfony2 project , i'm having little trouble grasping what's going on event listener/subscribers.

i want have event subscriber adds role (blog_user) fosuser entity after user registers account.

here's i've got far:

registration listener:

namespace myblog\sitebundle\eventlistener;  use fos\userbundle\fosuserevents; use fos\userbundle\event\formevent; use symfony\component\eventdispatcher\eventsubscriberinterface;  class registrationlistener implements eventsubscriberinterface {     public static function getsubscribedevents() {         return array(             fosuserevents::registration_success => 'onregistrationsuccess',         );     }     public function onregistrationsuccess(formevent $event){         $rolesarr = array('role_user', 'blog_user');          $user = $event->getform()->getdata();         $user->setroles($rolesarr);     } } 

services.yml:

services:     myblog_user.registration_listener:         class: myblog\sitebundle\eventlistener\registrationlistener         arguments: []         tags:             - { name: kernel.event_subscriber } 

security.yml:

access_control:     - { path: ^/blog/, role: blog_user } 

so far when register new user, can't access /blog route (which set of crud screens) - "access denied" message expected user without blog_user role.

edit:

my code appear add role user in database. in fos_user table under roles user has this:

a:1:{i:0;s:9:"blog_user";} 

it seems access_control doesn't see however.

 {% if is_granted('blog_user') %} 

is_granted fails - can't see roles user has...

as explained in comments, problem in role name. roles must start role_. solution set role hierarchy lite that

role_blog_user: role_user 

quote documetation

all roles must begin role_ prefix managed symfony2. if define own roles dedicated role class (more advanced), don't use role_ prefix.
