Witam,
Mam w aplikacji zaimplementowane logowanie z wykorzystaniem konta na
Facebook
Tweeter
LinkedIn
Google
i GitHub
użyte gemy:
gem 'omniauth'
gem 'omniauth-oauth2'
gem 'omniauth-facebook'
gem 'omniauth-github'
gem 'omniauth-google-oauth2'
gem 'omniauth-linkedin'
gem 'omniauth-twitter'
W aplikacji wykorzystuję Devise i w pliku config/initializers/devise.rb deklaracje providerów mam tak zrobione:
config.omniauth :facebook, ENV["FACEBOOK_KEY"], ENV["FACEBOOK_SECRET"], { :scope => 'email, offline_access', :client_options => {:ssl => {:ca_file => '/usr/lib/ssl/certs/ca-certificates.crt'}}}
config.omniauth :twitter, ENV["TWITTER_KEY"], ENV["TWITTER_SECRET"], { :scope => 'r_fullprofile, r_emailaddress', :client_options => {:ssl => {:ca_file => '/usr/lib/ssl/certs/ca-certificates.crt'}}}
config.omniauth :linkedin, ENV["LINKEDIN_KEY"], ENV["LINKEDIN_SECRET"], { :scope => 'r_fullprofile r_emailaddress', :client_options => {:ssl => {:ca_file => '/usr/lib/ssl/certs/ca-certificates.crt'}}}
config.omniauth :github, ENV['GITHUB_KEY'], ENV['GITHUB_SECRET'], scope: "user, public_repo"
config.omniauth :google_oauth2, ENV['GOOGLE_KEY'], ENV['GOOGLE_SECRET'], {}
No pięknie działa ze wszystkimi portalami poza GitHub 
Otrzymuję w Heroku logs takie coś:
Parameters: {"code"=>"e1536d0fdec9b4d23faf", "state"=>"e3118babae5dfe4faf560ff5798fd47be15f6fc7d42a75fb"}

Czy ktoś z Was ma pomysł, o co chodzi z tym:
NoMethodError (undefined method `persisted?' for nil:NilClass):
2014-10-21T07:21:34.611361+00:00 app[web.1]: app/controllers/omniauth_callbacks_controller.rb:7:in `all'
kod:
1) class OmniauthCallbacksController < Devise::OmniauthCallbacksController
2)
3) skip_before_filter :authenticate_user!
4) def all
5) p env["omniauth.auth"]
6) user = User.from_omniauth(env["omniauth.auth"], current_user)
7) if user.persisted?
flash[:notice] = "You are in..!!! Go to edit profile to see the status for the accounts"
sign_in_and_redirect(user)
else
session["devise.user_attributes"] = user.attributes
redirect_to new_user_registration_url
end
end
.....
....
Wdzięczny będę za wszelkie sugestie
