Subject: Re: How to Convert an Object into a Hash

I don't know how the internals of contract_payment's class is set up, 
but you could do this in some cases:
daniel@daniel-desktop:~$ irb
 >> class Car
 >>   def initialize(color, make, model_year, owner)
 >>     @color, @make, @model_year, @owner = color, make, model_year, owner
 >>     end
 >>   end
=> nil
 >> myCar = Car.new("green", "Ford", 2007, "Me!")
=> #<Car:0xb7bd566c @color="green", @owner="Me!", @model_year=2007, 
@make="Ford">
 >> myCar.instance_variables
=> ["@color", "@owner", "@model_year", "@make"]
 >> properties = Hash.new
=> {}
 >> myCar.instance_variables.each {|x| properties[x[1..-1]] = 
myCar.instance_variable_get(x) }
=> ["@color", "@owner", "@model_year", "@make"]
 >> properties
=> {"model_year"=>2007, "make"=>"Ford", "color"=>"green", "owner"=>"Me!"}
 >>
