Hi Friends,
I am using Rails 1.2.6 in my application. I need to use the functionality of "dirty fields" (getting previous value of an object's attributes). I know "Dirty fields" features are already in edge rails. But i want to do the same in my current rails version... any ideas?
i tried the dirty plugin which is given here (http://dev.rubyonrails.org/browser/trunk/activerecord/lib/active_record/dirty.rb?rev=9127)
After including this module (from the above url) to my active record base class, my active record object are able to show the status - whether object is changed or not (using the method - obj.changed? ) but they are unable to show the changed values, instead it always give an empty hash ( method - "obj.changes")
I need to get the previous value for the modified object's attributes
can anybody help on this?
