class SessionController < ApplicationController
def create
if using_open_id?
open_id_authentication(params[:openid_url])
else
password_authentication(params[:login], params[:password])

end
protected

def open_id_authentication(openid_url)
authenticate_with_open_id(openid_url, :required => [:nickname, :email]) do |result, identity_url, registration|
if result.successful?
@user = User.find_or_initialize_by_identity_url(identity_url)
if @user.new_record?
@user.login = registration['nickname']
@user.email = registration['email']
@user.save(false)
end
self.current_user = @user
successful_login
