Quick and Dirty Integration of elasticsearch api with rails

Take the following with a grain of salt ...

We started prototyping with ES & Rails about 2 days ago and I quickly discovered that things became a bit unwieldy the more I utilized elasticsearch. For now I am running with this type of integration with rails 3.2.15 to assess elasticsearch.

While we have done preliminary reviews on how to set up a production environment (still scratching my head on how to handle the split brain bug) , there's certainly plenty of what I'm not aware of, so if you see a fault in this approach, please let me know.

I may update this later on with a couple of convenience methods on the data models ...

Ace editor component for Ember.

A two-way binding is set up between value and the text in the editor.
Configure Ace in the aceInit callback.

Template

{{ace-editor value=value aceInit=aceInit class="editor"}}

	#!/bin/sh

	host=localhost:9200

	curl -X DELETE "${host}/test"

	curl -X PUT "${host}/test" -d '{
	"settings" : { "index" : { "number_of_shards" : 1, "number_of_replicas" : 0 }}
	}'

	import os
	import sys


	# constants, configure to match your environment
	HOST = 'http://localhost:9200'
	INDEX = 'test'
	TYPE = 'attachment'
	TMP_FILE_NAME = 'tmp.json'

	# A CORS (Cross-Origin Resouce Sharing) config for nginx
	#
	# == Purpose
	#
	# This nginx configuration enables CORS requests in the following way:
	# - enables CORS just for origins on a whitelist specified by a regular expression
	# - CORS preflight request (OPTIONS) are responded immediately
	# - Access-Control-Allow-Credentials=true for GET and POST requests
