What is a queue?

Anytime you go out for a meal and the hostess informs you that there is a wait and you agree to be added to a waitlist, you are being put into a queue. A queue is at it's core nothing more than a line. In fact, in the UK they call waiting in line queueing.

Our queue when you arrive -

[
  {"name": "Bob"},
  {"name": "Karen"}
]

Setting up the base application

1. Install rails

$ gem install rails -v 5.0.0.beta1 --no-ri --no-rdoc

2. Create a new application

$ rails _5.0.0.beta1_ new blog --skip-spring

Rails 5 and ActionCable

Assumptions: The application already exists. You have two models article.rb and comment.rb. Articles have two attributes, title and text. Comments have two attributes, text and article_id. See these instructions if you need help getting started.

Routes

Assuming that you are nesting your :comments resources inside of :articles, mount ActionCable and make sure you have a root.

config/routes.rb

Rails.application.routes.draw do

	// Testing API routes

	module.exports = vows.describe('Feature > SubFeature').addBatch(setupBatch).addBatch({
