Integrate Gem/Engine and main Rails app

If you prefer to watch video tutorials with live-coding, then check out this series I recorded with the same contents as in this article: Egghead.io - Introduction to Reactive Programming.

Here's what I did to get things working.

$ git clone --no-hardlinks original-repo copied-repo

$ cat hello.rb.md
Here's a simple program

    puts "Hello, world"
$ ruby litrb.rb < hello.rb.md

Hello, world

	class DecoratorClone
	def initialize(model)
	@model = model
	end

	def method_missing(m, *args)
	raise NameError, "Decorator method '#{m}' not found" unless @model.respond_to?(m)
	@model.send(m, *args)
	end
	end

	# In order for gpg to find gpg-agent, gpg-agent must be running, and there must be an env
	# variable pointing GPG to the gpg-agent socket. This little script, which must be sourced
	# in your shell's init script (ie, .bash_profile, .zshrc, whatever), will either start
	# gpg-agent or set up the GPG_AGENT_INFO variable if it's already running.

	# Add the following to your shell init to set up gpg-agent automatically for every shell
	if [ -f ~/.gnupg/.gpg-agent-info ] && [ -n "$(pgrep gpg-agent)" ]; then
	source ~/.gnupg/.gpg-agent-info
	export GPG_AGENT_INFO
	else

	require "active_record"

	ActiveRecord::Base.establish_connection('postgres:///testing')
	ActiveRecord::Migration.verbose = false

	ActiveRecord::Migration.class_eval do
	create_table :played_quizzes, force: true do \|t\|
	t.integer :player_ids, array: true
	t.json :quiz_snapshot
	end

	# Let's try out a table with kramdown class tag

	\| A simple \| table \|
	\| with multiple \| lines\|
	{: .my-class }
