Demonstrates that you cannot define class methods using the Concerning gem (https://github.com/37signals/concerning)
Given this class definition:
class User < ActiveRecord::Base
attr_accessible :name
concerning :Programmers do
module ClassMethods
def programmer?
true
end
end
end
module Managers
extend ActiveSupport::Concern
module ClassMethods
def manager?
true
end
end
end
include Managers
endYou get this in the console:
irb(main):001:0> User.manager?
=> true
irb(main):002:0> User.programmer?
NoMethodError: undefined method `programmer?' for #<Class:0x007f9641beafd0>
