Fabrication::MisplacedFabricateError while using Fabrication Gem on Rails 2.3.16

Question

I am using Fabrication gem v-2.5.0 on Rails 2.3.16 but get the following errors when I run the unit test cases:

Below is the code snippet :

First case

Fabricate(:some_modal) 
Fabrication::MisplacedFabricateError: # from /Users/user_xyz/.rvm/gems/ree-1.8.7-        2011.03@project/gems/fabrication-2.5.0/lib/fabrication.rb:51:in `Fabricate' from (irb):3

Second case

Fabricate(:some_other_modal)
SyntaxError: /Users/user_xyz/.rvm/gems/ree-1.8.7-2011.03@project/gems/fabrication-2.5.0/lib/fabrication/generator/active_record.rb:8: syntax error, unexpected ':', expecting ')' ...ttributes, without_protection: true)

Can someone please help me resolve these.

Modal Class :

  class ErrorCode
      attr_accessor :mappings
      has_many :error_code_mappings
  end

Fabricator :

Fabricator(:error_code) do
  application_id 77
  error_code_mappings(:count => 3) { |error_code, i| Fabricate.build(:error_code_mapping,      :error_code => Fabricate.build(:error_code, :code => error_code.code + i))}
end

Unit test file:

require 'test_helper'

class ErrorCodeTest < ActiveSupport::TestCase
  context "ErrorCode" do
    setup do
      @error_code = Fabricate.build(:error_code)
      assert(@error_code.valid?)
    end
   should "have setter for mapping attribute" do
      assert_respond_to(@error_code, :mappings=)
   end
end

Fabrication requires Ruby 1.9 and higer version. And the current version of ruby that is being used as per the given code snippets is REE 1.8.7.

Upgrade your ruby version & then u can get it working!
