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

can anybody suggest a fix for this error?

Doug,

Can you duplicate the problem in a non rails example?
Would save me some time...

this is the working code i used as a basis for my rails app:

require 'test/unit'
require 'rools'
require 'rools/base'
require 'logger'

class Person
attr_accessor :name, :personicx

def initialize(name, personicx)
@name = name
@personicx = personicx
end
end

class OfferTest < Test::Unit::TestCase

def setup
#Rools::Base.logger = Logger.new(STDOUT)
end

def test_offers

sally = Person.new("sally", 1)
peggy = Person.new("peggy", 2)

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

rules.assert peggy

puts $offer

end
end

this code works in a command prompt (ruby offer_test.rb), and, i
thought all i would need to do to use it in a rails app was add:

require 'rools'

and

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

however, the line above is what generates the error:

rule_0

Anonymous modules have no name to be referenced by

in the rails app

i don't know how to get the code to fail in a non-rails app

thought you might want to see the full error:

Rools::RuleCheckError in OfferController#index

any .csv file i try to read in a controller class generates the same
error, for instance:

rules = Rools::RuleSet.new '/rails/purl/businessrules/salutations.csv'

generates the error:

rule_0
Anonymous modules have no name to be referenced by

thanks, pat, for the fix...

moved my anonymous Person class to app\models and everything is ok

should have had it there in the first place as i will eventually have
a persons table in my database

learned something new, today, about classes and ruby and rails

Rools does rule!
