I tried integrating omniauth with Hartl tutorial user signup authentication. I thought about switching the hartl tutorial authentication to Devise and then Devise to omniauth (since their is a Railscast episode for that), but I'm worried the switch from Hartl to Devise will be the most difficult integration out of the options. What do you think?
Currently if I go to http://0.0.0.0:3000/authentications I will be taken to a login page for facebook. Once I click on the link I get logged into facebook. Score! But then I am redirected to the root route with:
where page shows me "Welcome to the Sample App: Sign up now!" as if I am not logged in. I've been confused by this whole process so if you can tell me where I went wrong I'd greatly greatly appreciate it.
class AuthenticationsController < ApplicationController
def index
@authentications = current_user.authentications if current_user
end
def create
omniauth = request.env["omniauth.auth"]
authentication = Authentication.find_by_provider_and_uid(omniauth['provider'], omniauth['uid'])
if authentication
flash[:notice] = "Signed in successfully."
sign_in_and_redirect(:user, authentication.user)
elsif current_user
current_user.authentications.create!(:provider => omniauth['provider'], :uid => omniauth['uid'])
flash[:notice] = "Authentication successful."
redirect_to authentications_url
else
user = User.new
user.apply_omniauth(omniauth)
if user.save
flash[:notice] = "Signed in successfully."
sign_in_and_redirect(:user, user)
else
session[:omniauth] = omniauth.except('extra')
redirect_to root_url
end
end
end
def destroy_facebook
@authentication = current_user.authentications.find(params[:id])
@authentication.destroy_facebook
flash[:notice] = "Successfully destroyed authentication."
redirect_to authentications_url
end

endYea I just dumped a lot on you. I have no direction. I followed Railscasts for omniauth: http://railscasts.com/episodes/235-omniauth-part-1?view=asciicast, http://railscasts.com/episodes/236-omniauth-part-2?view=asciicast
This same error gave me a headache once. Check if the email you use for facebook is already in your database. If it's there then delete it and it should work.
