Batch insert images into ES index

es.rb

website = Website.first
es = ElasticSearch.new('localhost:9200', :index => "tags", :type => "image")

count = 0
images = website.images.includes(:meta_tags).where("copied_image_id is ? and deleted = ?", nil, 0);
images.each_slice(1000) do |images|
  puts count if count % 10 == 0
  es.bulk do |client|
    images.each do |image|
      tags = image.meta_tags.map {|t| t.category_and_name }
      client.index({:id => image.id, :tags => tags, :code => image.code}, :id => image.id)
      count = count + 1
    end
  end
end

Great thanks. It's a clean solution. I'll try it out with a lot of images.
If this works we can try putting the images into a beanstalkd queue to batch the inserts.
