Anyone knows how to use namespace with acts_as_versioned-0.5.1? Model example:
class Namespace::MyModel < ActiveRecord::Base
require 'acts_as_versioned'
acts_as_versioned(:class_name => "Namespace::MyModel", :table_name => my_model_versions')
...
The error looks like: NameError in Namespace::MyModel
wrong constant name Namespace::MyModelVersionsAssociationExtension
