… how other adapters work.

This also allows you to execute stored procedures from a class without having to inherit from ActiveRecord::Base (for instance, because there is no table to map to):

class NoTableModel
  extend ActiveRecord::ConnectionHandling
  include ActiveRecord::Core

  self.configurations = Rails.configuration.database_configuration
  self.establish_connection("#{Rails.env}_some_database".to_sym)

  def self.execute_procedure(*args)
    self.connection_pool.with_connection { |conn| conn.execute_procedure(*args) }
  end
end
