ruby on rails - Omniauth-facebook with Devise: "Missing passthru" errors -

i have devise authentication installed no problems. i'm trying add option log in facebook, using omniauth-facebook.

i followed instructions in this guide, i'm getting errors missing "passthru" documentation, when visiting url localhost:3000/auth/facebook.

here's first error got:

unknown action action 'passthru' not found registrationscontroller 

i tried bandaid fix adding empty "passthru" action controller:

def passthru end 

and resolved error, got different 1 in return:

template missing missing template registrations/passthru, devise/registrations/passthru, devise/passthru, application/passthru {:locale=>[:en], :formats=>[:html], :handlers=>[:erb, :builder, :raw, :ruby, :jbuilder, :coffee]}. searched in: * "/home/user/project/app/views" * "/home/user/.rvm/gems/ruby-2.0.0-p648@railstutorial_rails_4_0/gems/devise-3.5.2/app/views" 

i tried creating "passthru.html.erb" in stated folders, error remained. in case, think these errors emblematic of deeper problem.

has else run problem? find on this question, none of answers helpful.
