extending find() in a horrible way..

Hi all,

I'm trying to add a default scope to all calls to find.

My method is really ugly and wondered if anyone had a better solution?
It also doesn't effect all the dynamic finder methods.

(I've posted this a couple of times but I'm not seeing it in google
groups.. not sure if this will work.)

cheers
-h

class LinkCategory < ActiveRecord::Base

def self.find(*args)
    options = args.last.is_a?(Hash) ? args.pop : {}
    sql = "site_id='#{some_integer}'"
    if options[:conditions] && !options[:conditions].empty?
      options[:conditions] += " AND #{sql}"
    else
      options[:conditions] = "#{sql}"
    end
    args << options
    super(*args)
  end

end
