Badgeable is an elegant DSL for awarding badges
Badgeable provides an elegant DSL for describing and awarding badges to your Ruby objects.
Describe the badges you want to award using the badge block. The only configuration directive required for each badge is the name of the badge and the name constant of the awarding class:
class Person include Mongoid::Document include Badgeable::Subject :nachos end badge "Nacho Nacho Man" do thing Nacho count 40 subject :person conditions do |nacho| nacho.spicy? end end
would award the “Nacho Nacho Man” badge to each Person who eats 40 nachos, and the last one was spicy.
class Person include Mongoid::Document include Badgeable::Subject references_many :meals end badge "Fancy Pants" do thing Meal subject :person count Meal.where(:price_cents.gte => 10000).count >= 12 end conditions do |meal| meal.restaurant.city != meal.eater.city end end
would award the “Fancy Pants” badge to the diner who has eaten 12 expensive meals where the awarding meal was out of town.
You can also award arbitrary badges using your own business logic by calling #award_badge(badge_name) on any Badgeable instance:
yehuda = Person.create(:name => "Yehuda Katz") yehuda.award_badge("Total Badass")
Badge recipient classes should include Badgeable::Subject. Extending an awarding class with Badgeable::Award will allow you to define badge blocks in the awarding class definition. You may also eval a separate file of badge definitions in the context of Badgeable::Award.
When used with Rails, Badgeable will look for badging definitions in Rails.root/lib/badges.rb
