copied!<p>I usually do this via a separate messaging daemon which loads the rails environment.</p> <p>So a very simplistic example would look like this in rails_root/script/myapp_daemon.rb :</p> <pre><code> #!/usr/bin/env ruby require 'rubygems' require 'amqp' require 'daemons' ENV["RAILS_ENV"] ||= "development" require File.dirname(__FILE__) + "/../config/environment" options = { :backtrace => true, :dir => '.', :log_output => true} Daemons.run_proc('myapp_daemon', options) do EventMachine.run do connection = AMQP.connect(:host => "127.0.0.1") channel = AMQP::Channel.new(connection) queue = channel.queue("/myapp_daemon", :durable => true) exchange = channel.direct("") queue.subscribe do |payload| obj = JSON.parse(payload) #... handle messages here, utilize your rails models Foo.create(...) end end end </code></pre> <p>You would also need the right gem requires in your Gemfile: amqp, daemons, eventmachine</p> <p>Then either run it manually alongside your app:</p> <pre><code>RAILS_ENV=development script/myapp_daemon.rb run </code></pre> <p>Or start it from one of your app initializers:</p> <pre><code>system('script/myapp_daemon.rb start') </code></pre> <p>To dig into amqp check out the following, this will give a nice high level overview: <a href="http://www.rubyinside.com/why-rubyists-should-care-about-messaging-a-high-level-intro-5017.html">http://www.rubyinside.com/why-rubyists-should-care-about-messaging-a-high-level-intro-5017.html</a></p> <p>This gives a very detailed explanation with working examples: <a href="http://rubydoc.info/github/ruby-amqp/amqp/master/file/docs/Exchanges.textile#Publishing_messages_as_immediate_">http://rubydoc.info/github/ruby-amqp/amqp/master/file/docs/Exchanges.textile#Publishing_messages_as_immediate_</a></p> <p>Finally see if Bunny accomplishes everything you need for the client, it is simpler: <a href="https://github.com/celldee/bunny/wiki/Using-Bunny">https://github.com/celldee/bunny/wiki/Using-Bunny</a></p> <p>Hope that helps</p>
