Subject: undefined method `debug' for nil:NilClass(NoMethodError

I created very simple AR code to add new record to MySQL table. But I
get " undefined method `debug' for nil:NilClass(NoMethodError)".

Here is the code:
======================================
require 'rubygems'
require 'active_record'

ActiveRecord::Base.establish_connection(
:adapter => "mysql",
:host => "localhost",
:user => "root",
:password => "samplepass",
:database => "db_demo"
)

class City < ActiveRecord::Base
end

City.create(:id => 4, :name => 'Washington')

last_city = City.find(:last)

if last_city
  puts %{#{last_city.name} is the last city}
else
  puts "There is no any City."
end
======================================

The code is so simple just like explained in
(http://rubylearning.com/satishtalim/ruby_activerecord_and_mysql.html)
and in the Ruby AR documentation. But that undefined method error pops
up anyway. I actually, so many developers encounter the same problem.
Still cannot find the solution.

Any suggestion is appreciated.
