rule_0, Anonymous modules have no name to be referenced by

[doug]

i created offer_test.rb to read offers.csv and tested ok

i take the code from the offer_test.rb file and put in
offer_controller.rb

i get error:
rule_0, Anonymous modules have no name to be referenced by

here is offers.csv:

rule-set,Define Offer
parameter,Person
Condition,Consequence
person.personicx == #{personicx},$offer = #{offer}
Personicx,Offer
1,College Student
2,General Consumer

here is offer_controller.rb:

class OfferController < ApplicationController

require 'rools'
require 'uri'

class Person

attr_accessor :name, :personicx

def initialize(name, personicx)

@name = name

@personicx = personicx

end

end

def index

a = "/store/show_by_tags/"

sally = Person.new("sally", 1)

peggy = Person.new("peggy", 2)

rules = Rools::RuleSet.new "/rails/purl/businessrules/offers.csv"

rules.assert sally

a += $offer

a = URI.escape(a)

redirect_to a

end

end
