yolo.rb

class ActiveRecord::Base
  class << self
    def inherited_yolo(klass)
      old_inherited(klass)
      klass.attr_accessible(*klass.column_names.map(&:to_sym)) unless klass.abstract_class?
    end
    alias_method :old_inherited, :inherited
    alias_method :inherited, :inherited_yolo
  end
