[kashiftufail]

i'm using omniauth-facebook,omniauth-twitter and omniauth-google in my app. But for google i have this error "The action 'google' could not be found for Users::OmniauthCallbacksController"

I use your strategy like

 def method_missing(provider)

 end

but i is working for facebook ,twitter if i remove these methods from my omniauthcallbackscontroller.

    def facebook
    end

   def twitter
   end

but unfortunately not working for google

Any help please?
