Overview

The null adapter lets all send messages enter into the ether and so is ideal for modes when you do not want to incur the overhead of a real adapter. You can not consume with this adapter however.

In your RosettaQueue definition block, and your using rails, you could base your adapter type on Rails.env:

RosettaQueue::Adapter.define do |a|

if Rails.env == 'production' || ENV["RUNNING_STORIES"] == "true"
  a.user = ""
  a.password = ""
  a.host = "localhost"
  a.port = 61613
  a.type = "stomp"
else
  a.type = "null"
end

end

(if you follow this example and are using stories be sure to set ENV = “true” in your helper.rb or env.rb file)
