Rails - Mar 2006 - Changing accessor list order

Ok, I''m pretty new to Rails and I''m building a bug tracker as
my first
real project. I have a situation where a bug can have multiple comments. 
Pretty simple.  When I show the comments on the screen, I want to make 
sure that they''re displayed in reverse order by date created.  I have 
used the following to change the order of @bug.comments:

class Bug < ActiveRecord::Base
  belongs_to :priority
  has_many :comments
  validates_presence_of :description, :priority

  def comments
    Comment.find :all, :order => ''created_at DESC''
  end
end

It works like a charm.  But, is there a better way to do this?  Should I 
be returning it as-is and reversing it in the view instead?

Ok, I think I already solved my own problem.  Array.reverse_each.  So 
many fantastic tricks that I still have yet to learn!

Oops, too vague.  To clarify, I removed the accessor override and just 
performed an Array.reverse_each in the view to list comments in reverse 
order.

See also the :order option for has_many relationships.

That''s even better.  I didn''t realize there were so many
options for
has_many.  Thx Tom.
