“Missing template” error in Omniauth (ruby-on-rails)

Question

I'm using OmniAuth for Facebook Authentication, and I keep getting this error:

Missing template authentications/index with
{:handlers=>[:rjs, :rhtml, :builder, :rxml, :erb], 
 :locale=>[:en, :en], :formats=>[:html]} in view paths

The view file is present in the app directory, but is apparently not seen.

Answer 1

add

resources :authentications

to your config/routes.rb file
