How can I compare an entry? @edit = Data.find(4) After this, user update some data en press submit. How can compare, is there any changes in new @edit and what is in database? Have user chnged any data or pressed just submit without changes?

Try this in the #update action. It's untested: @edited_data = Data.new(params[:data]) @original_data = Data.find(params[:id]) if @edited_data == @original_data # The data is NOT changed... else # The data IS changed... end I don't know if the == operator works in this case, but try it out and come back if you get problems. :) -- Cheers, David Knorr http://twitter.com/rubyguy
