Moved the problem along

Unfortunately the problem does not appear to be a routes problem but a
not initialised authlogic problem. By changing the App.Controller
methods I have now moved the problem to the create procedure after
logging on. I managed to create a user from the console and Authlogic
filled in all the special fields. But logging on and calling the
create session (call Authentication) causes the same error
undefined method `underscore’ for nil:NilClass
which occurs when calling @authentication.save.

def create
@authentication = Authentication.new(params[:authentication])
if @authentication.save
flash[:notice] = “Login successful!”
redirect_to root_url
else
render :action => :new
end
end

My App.Controller now has the session/user checking methods and cause
no problems. (so far)

private
def current_user
return @current_user if defined?(@current_user)
@current_user = current_user_session && current_user_session.user
end

def current_user_session
  return @current_user_session if defined?(@current_user_session)
  if defined?(Authentication.Find) then
   @current_user_session = Authentication.find
  else
   @current_user_session=nil
  end

end

I am using rails 2.3.8 and Authlogic 2.1.6, and I like to try and keep
to one word descriptions of models and controls so Authentication
instead of UserSession.
