About Badgeable

Badgeable is an elegant DSL for awarding badges

Overview

Badgeable provides an elegant DSL for describing and awarding badges to your Ruby objects.

Usage

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
  embeds_many :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.

Setup

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; rails g badgeable:definitions to get started.

Supported ORMs

• Mongoid
• ActiveRecord - badgeable_active_record
