ActiveRecord nil patch

nil_patch.rb

def nil.method_missing(method, *args)
  (@@activeRecordClasses ||= ObjectSpace.each_object(Class).find_all { |c|
    c.respond_to?(:ancestors) && c != ActiveRecord::Base && c.ancestors.include?(ActiveRecord::Base)
  }).choice.order("rand()").first || self.method_missing(method, *args)
