version_fu in Rails 2.1.1

Hi,

So I read about how acts_as_versioned doesn''t play so well with the
latest Rails version.

I got hold of an alternative, version_fu, but I am still having
trouble. http://github.com/jmckible/version_fu


I''m getting the following error when trying to save the versioned
model:
>> type = StatisticType.find(1)
>> type.name = ''bob''
=> "bob">> type.saveNoMethodError: undefined method `version='' for
#<StatisticType::Version:0x244c3a0>

	from /usr/local/lib/ruby/gems/1.8/gems/activerecord-2.1.1/lib/
active_record/transactions.rb:106:in `save''


Here''s the migration I used to prepare things (I checked in the
database to make sure the changes are there):

class AddStatisticTypeVersioning < ActiveRecord::Migration

  def self.up
    create_table :statistic_type_versions do |t|
      t.integer :statistic_type_id, :statistic_category_id
      t.string  :name, :time_filter, :unit
      t.text    :sql
      t.timestamps
    end
    add_column :statistic_types, :version, :integer, :default=>1
  end

  def self.down
    remove_column :statistic_types, :version
    drop_table :statistic_type_versions
  end

end

Am I making some simple mistake?

Many thanks in advance

Re: version_fu in Rails 2.1.1

table ... Duh ....
