Spree extension for Product Group and Scope. This functionality was removed from Spree 1.1 and into this extension.
In your application Gemfile, add this gem after the Spree gem:
gem 'spree' gem 'spree_product_groups', :git => 'firstname.lastname@example.org:spree/spree_product_groups.git'
bundle rails g spree_product_groups:install
Be sure to bundle your dependencies and then create a dummy test app for the specs to run against.
bundle bundle exec rake test_app bundle exec rspec spec
