acts_as_versioned for a set of columns

acts_as_versioned is a great plugin for versioning a set of model attributes transparently every time you save. The plugin seems to be built with exclusion in mind (version all except these) but to get it to work only on a specific set of columns, this simple trick can be applied:

class Foo < ActiveRecord::Base
  acts_as_versioned :if_changed => [:description_t]
  def versioned_attributes; [:description_t, :planspace_updated_by_id]; end
end
