This is why the link doesn't work. A user (current_user) does not have _an_ appointment, she has _many_ appointments. If you want the latest one, then use

current_user.appointments.order(:appointment_date).last if current_user.appointments.any?

You could put that in a helper so it doesn't make your views so ungainly.
