Add find_each and find_in_batches functionality to ActiveResource

batch_resource.rb

# Drop this into config/initializers 
# The resource being consumed should honour the :page parameter (works great with will_paginate)

module ActiveResource
  module Batches
    module ClassMethods
      
      def find_each(options = {})
        find_in_batches(options) do |batch|
          batch.each do |entry|
            yield entry
          end
        end
      end
    
      def find_in_batches(options = {})
        finished = false
        page = 1
        while not finished do
          begin
            batch = find(:all, :params => options.merge(:page => page))
            if batch.empty?
              finished = true
            else
              yield batch
            end
            page += 1
          end
        end
