Rails 2.2.2 Ruby 1.8.5 I am attempting to extend AR with a generalized audit attribute setter. I have written this code, which does not work for reasons unknown to me. Perhaps someone here can explain why it does not. # Put this in config/initializer as active_record_addins.rb module ActiveRecord module HLLAuditStamps def self.included(base) super # alias_method_chain :create, :audit # is the same as: # alias_method :create_without_audit, :create # alias_method :create, :create_with_audit base.alias_method_chain :create, :audit base.alias_method_chain :update, :audit end private def create_with_audit write_audit_fields # Now we call our alias to the original method create_without_audit end def normal_time_now if base.class.default_timezone == :utc return DateTime.now.utc else return DateTime.now end end def update_with_audit write_audit_fields update_without_audit end def write_audit_fields write_attribute('accessed_at', normal_time_now) if \ respond_to?('accessed_at') write_attribute('accessed_on', normal_time_now) if \ respond_to?('accessed_on') end end end What I intend is that whenever the AR create or update method is called then the attributes specified in write_audit_fields are set to the value provided by normal_time_now. They are not and I cannot tell why. Any suggestions as to what I am doing wrong?

Sorry this isn't a direct answer to your question, but I just wanted to ask if you have looked at any of the existing auditing plugins to see if they support your needs? For example: http://github.com/collectiveidea/acts_as_audited/tree/master

I have since read that the technique I am trying to employ has been broken by a change to Rails (http://dev.rubyonrails.org/changeset/7749) but I have been unable to discover a working alternative.
