Hello, I have a freeze field in a table (that I can''t change). When I try to find a record in this table I have the exception : C:/DATA/InstantRails-2.0/ruby/lib/ruby/gems/1.8/gems/ activerecord-2.1.0/lib/active_record/attribute_methods.rb:104:in `instance_method_already_implemented?'' C:/DATA/InstantRails-2.0/ruby/lib/ruby/gems/1.8/gems/

I understand that ActiveRecord supports the "optimistic offline lock"-pattern through magic fields (created_at, updated_at). However, a scaffolded CRUD-Controller doesn''t generate the necessary code to support this feature (the model state gets lost between two action calls). What is the best practice to prevent users from overwriting objects with outdated data ? --
