Question

I have been trying for days to setup my Omniauth for facebook I don\'t know what am I doing wrong.

I am not able to get the email of the user. The returned hash only

You need to request the permissions. For example, to request email, user_birthday and read_stream permissions and display the authentication page in a popup window:

Rails.application.config.middleware.use OmniAuth::Builder do
  provider :facebook, ENV['FACEBOOK_KEY'], ENV['FACEBOOK_SECRET'],
       :scope => 'email,user_birthday,read_stream', :display => 'popup'
end

Please check this Omniauth-facebook if you have any doubts.
