I am using Devise with Omniauth to have users sign into my app with Facebook. I used the Railscast tutorials to get it up and running. If a user is already a member of my site authenticating through facebook works fine. The problem comes in when authenticating a new user with facebook. When it goes to create a new user for my User model I get the "users.encrypted_password may not be NULL" error. I can't figure out how to pass over the password to the User model from Facebook information. This is what I have: authentations_controller.rb 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 new_user_registration_url end end end user.rb def apply_omniauth(omniauth) self.email = omniauth['user_info']['email'] if email.blank? authentications.build(:provider => omniauth['provider'], :uid => omniauth['uid']) end def password_required? (authentications.empty? || !password.blank?) && super end Any help would be great, thanks in advance!
