Paths of Glory sets you on the road to achievements!

In short, it's a re-usable model for creating an achievement system.

It's extracted from http://peertester.com and inspired by: http://stackoverflow.com/questions/885277/how-to-implement-an-achievement-system-in-ror

Paths of Glory is easy to install.

As a plugin:

./script/plugin install git://github.com/paulca/paths_of_glory.git

Or as a gem. Add this to your environment.rb:

gem install paths_of_glory

config.gem 'paths_of_glory', :lib => false

Then generate the migration:

./script/generate paths_of_glory

And run the migration:

rake db:migrate

This creates the tables.

Then, in your User model:

class User < ActiveRecord::Base
  include Achievements
end

and in config/environment.rb, add app/models/achievements to your load path:

config.load_paths += %W( #{RAILS_ROOT}/app/models/achievements )

Paths of Glory gives you access to a DSL to generate achievements. Achievements can have multiple levels or can just be standalone achievements.

The pattern is basically:

Create an achievement:

./script/generate achievement Glory

This gives you app/models/achievements/glory.rb and app/models/achievements/glory_observer.rb with some bootstrapped code.

You're on your own after that. Have fun!

You can run the tests by checking out the code into vendor/plugins of a Rails app and running:

rake
