When was callback registration introduced?

I'm using Rails 2.3.5 and finding that for lines like these below in a model, the block is never executed. Am I doing something wrong or was this introduced in a later version of Rails?

  before_create :preprocess_score

  def preprocess_score     puts "HERE: #{__LINE__}"     self['score'] = Token.process(token_counts, feed.user_id)   end


  before_create do |a|     puts "HERE"     a.write_attribute('score', Token.process(token_counts, a.feed.user_id))   end

TIA,   Jeffrey

Never mind, bitten by fixtures. They aren't created normally and the callbacks aren't called.
