Rails - May 2006 - Order parents when displaying children question

Hi,

I want to show a series of links belonging to a specific category.
The links will be shown grouped by category, but how can I alter the
order of the categories?

I have a field in my database called position with the order in which 
they
should appear.

MODELS:

class Category < ActiveRecord::Base

  has_many :links
  validates_uniqueness_of :category, :message => "already exists"

end

class Link < ActiveRecord::Base

  belongs_to :category
  validates_associated :category
  validates_presence_of :link
  validates_presence_of :url

  def self.get_links
    find(:all, :order => :category_id)
  end

end

Any help would be great!

Maarten
