Much better, though still not sure about what you mean by 'return' the value that exists... Where are you returning it from and to? If you mean that in the update action of the controller you want to access the current value of the record in the db before saving the new values, then, assuming that you are using the normal method like @record = MyModel.find(params[:id]) if @record.update_attributes(params[:sample]) Then between those two lines @record has the original values from the db. update_attributes picks up the data from params and updates the db.
