The bit @appointments.group_by { |appointment|
appointment.start.strftime("%Y-%d-%d") } builds a hash where the key
part of each entry in the hash is the date and the value part is an
array of appointments for that date, then
.each_pair do |start_date, appointments| starts a block with
start_date containing the date and appointments containing the
appointments for that date. so you want then to say something like
<% appointments.each do |appointment| %> to iterate through the
appointments for that date. You are getting the error below because
appointment is not defined.
I have to say that this is quite a complex bit of code for a beginner
to get to grips with, but worth the effort to understand.
