Devise methods in helper file?

Question

I have a helper module ModelHelper. I want to use user_signed_in? method inside that helper module. But it shows error. How can I call this method inside helper file.

Answer 1

Method user_signed_in? defined in the Devise::Controllers::Helpers::ClassModule module. Long story short it just checks if scope authenticated in warden. So you can try to check it without Devise helpers

def #{mapping}_signed_in?
  !!current_#{mapping}
end

def current_#{mapping}
  @current_#{mapping} ||= warden.authenticate(scope: :#{mapping})
end
