Okay, thanks a lot. That really helps. For the logged_in_user, that
would be a User instance method, right? Something like:
Class User < ActiveRecord::Base
def return_instructions_array
instructions = Instructions.return_array(self.appointments)
end
end
This would be an Instructions class method...is this better than an
Instruction instance method? like:
Instructions.new.return_array(self.appointments)
I'm never really sure which is better.
