ActiveModel based class does not create the same results as an ActiveRecord equivilent

Question

Hi, I am developing a Rails 3 app in a largely tabless capacity. I am using savon_model and ActiveModel to generate similar behaviour to ActiveRecord equivalents. Below is my code:

class TestClass
  include Savon::Model
  include ActiveModel::Validations

  # Configuration
  endpoint "http://localhost:8080/app/TestService"
  namespace "http://wsns.test.com/"

  actions :getObjectById, :getAllObjects

  attr_accessor :id, :name

  def initialize(hash)
    @id = hash[:id]
    @name = hash[:name]
  end

  client do
    http.headers["Pragma"] = "no-cache"
  end

  def self.all
    h = getAllObjects(nil).to_array
    return convert_array_hash_to_obj(h, :get_all_objects_response)
  end

  def self.find(id)
    h = getObjectById(:arg0 => id).to_hash
    return convert_hash_to_obj(h, :get_object_by_id_response)
  end

private

  def self.convert_array_hash_to_obj(arrayhash, returnlabel)
    results = Array.new

    arrayhash.each do |hash|
      results << convert_hash_to_obj(hash, returnlabel)
    end

    return results

  end

  def self.convert_hash_to_obj(hash, returnlabel)
    return TestClass.new(hash[returnlabel][:return])
  end

end

OK, so everything works as expected; values are pulled from the web service and onto the page. Unfortunately, when I look at the html produced at the client side there are some issues. The Show links are along the following lines:

/testclasses/%23%3CTestClass:0xa814cb4%3E

instead of...

/testclasses/1

So, I did a print of the object (hash?) to the console to compare the outputs.

[#<System:0xa814cb4 @id="1", @name="CIS">]

instead of what I believe it should be...

[#<System id="1", name="CIS">]

I have three questions:
1: What is the hex suffix on my class name when it is printed out
2: How can I modify my class to match the desired output when printed to the console?
3: Why are the frontend links (Show, Edit, Delete) broken and is there an easy fix?

Thanks so much for your time and apologies for rubbish code / stupid questions. This is my first Ruby or Rails app!
