Model and Attribute original Value

Rails
1

Hi Everyone,

Is there a way to when you find a record to keep the original value of
the attributes. This would allow to see if an attribute has changed at
save time and then do something. I am sure there is an cool way in
rails to do this!

Thanks…

You can store it in the #after_find hook:

class Thing < ActiveRecord::Base
def after_find
@original_name = name
end
end

Have a look at acts_as_audited it does exactly what you want.
