OmniAuth Facebook expired token error

Question

I am using OmniAuth to get access to Facebook in my app. I am using the fb_graph gem: https://github.com/nov/fb_graph to post to Facebook. I am running omniauth-0.3.0 on Heroku

You can simply update the token when you create the session.

class SessionsController < ApplicationController  
def create  
  auth = request.env["omniauth.auth"]  
  user = User.find_by_provider_and_uid(auth["provider"], auth["uid"]).tap do |u|
           u.update_attributes(:token => auth["credentials"]["token"]) if u
         end || User.create_with_omniauth(auth)
  session[:user_id] = user.id  
  redirect_to root_url, :notice => "Signed in!"  
end
