Something like
@instructions = logged_in_user.appointments.collect { |a| [a.instruction] }
Though I think I would consider something like putting this in a
method of User that returned an array of instructions for that user.
Or a class method or User that does it for the current logged in user.
Dependent on the rest of your requirements of course. You might want
to consider a class member of Appointments that takes an array of
appointments and returns an array of instructions.
