This is an example of how to use ActiveRecord without Rails:

   1  ['/model', '/db'].each do |folder|
   2    $:.unshift File.dirname(__FILE__) + folder
   3  end
   4  
   5  require 'test/unit'
   6  require 'rubygems'
   7  require 'activerecord'
   8  
   9  ActiveRecord::Base.logger = Logger.new(File.dirname(__FILE__) + '/debug.log')
  10  ActiveRecord::Base.configurations = YAML::load(IO.read(File.dirname(__FILE__) + '/config/database.yml'))
  11  ActiveRecord::Base.establish_connection('sqlite3')
  12  
  13  require 'schema'
  14  

Schema contains, for example:

   1  ActiveRecord::Schema.define :version => 0 do
   2    create_table :languages, :force => true do |t|
   3      t.string :name
   4    end
   5  end
