Elasticsearch

This repository contains ActiveModel, ActiveRecord and Ruby on Rails integrations for Elasticsearch:

• ActiveModel integration with adapters for ActiveRecord and Mongoid
• Enumerable-based wrapper for search results
• ActiveRecord::Relation-based wrapper for returning search results as records
• Model methods such as search, mapping, etc
• Pagination support
• Rails application templates

NOTE: This is a pre-release version: feedback welcome via Github issues, e-mail or IRC. Many more features, such as automatic hooking into Rails' notifications, Elasticsearch persistence for models, etc. are planned or being worked on.

Installation

The libraries are compatible with Ruby 1.9.3 and higher.

Install the elasticsearch-model and/or elasticsearch-rails package from Rubygems:

gem install elasticsearch-model elasticsearch-rails --pre

To use an unreleased version, either add it to your Gemfile for Bundler:

gem 'elasticsearch-model', git: 'git://github.com/elasticsearch/elasticsearch-rails.git'
gem 'elasticsearch-rails', git: 'git://github.com/elasticsearch/elasticsearch-rails.git'

or install it from a source code checkout:

git clone https://github.com/elasticsearch/elasticsearch-rails.git
cd elasticsearch-model
bundle install
rake install
cd elasticsearch-rails
bundle install
rake install

Usage

This project is split into two separate gems:

• elasticsearch-model, which contains model-related features such as setting up indices, search method, pagination, etc

• elasticsearch-rails, which contains features for Ruby on Rails applications

Example of a basic integration into an ActiveRecord-based model:

require 'elasticsearch/model'

class Article < ActiveRecord::Base
  include Elasticsearch::Model
  include Elasticsearch::Model::Callbacks
end

Article.import

@articles = Article.search('foobar').records

You can generate a fully working Ruby on Rails application with a single command:

rails new searchapp --skip --skip-bundle --template https://raw.github.com/elasticsearch/elasticsearch-rails/master/elasticsearch-rails/lib/rails/templates/01-basic.rb

Please refer to each library documentation for detailed information and examples.
