module Audited::Auditor::ClassMethods

def audited(options = {})


any create, update or destroy operation.
* +require_comment+ - Ensures that audit_comment is supplied before

end
audited :except => :password
class User < ActiveRecord::Base

You can add to those by passing one or an array of fields to skip.
[self.primary_key, inheritance_column, 'lock_version', 'created_at', 'updated_at']

By default, Audited will audit all but these fields:
* +except+ - Excludes fields from being saved in the audit log.
* +only+ - Only audit the given attributes
