RoR fb_graph application feed

I am using fb_graph gem for Ruby on Rails. I want to post a message on wall but the problem is that when I post the message (feed) it is posted by my user instead of my application, on the application's wall..

so it looks like
   Name Surname
   message content
   via application_name
and I want it to be
    message content

My code is:

application =
application.feed!(:message => 'test', :access_token => access_token)


I have found solution to this question. I have generated access token for application instead of user. This can be found on
