Prepare your application for the old age

Since I didn't have any slides during the talk, here are some resources that cover similar topics and/or were mentioned during the talk itself.

Happy hacking!

WARNING: be careful what you do with this.

Create a scripts directory in your Rails app root (if it doesn't already exist) and put the script inside

	# register services
	Application.register :session do
	SessionStore.new(store: Application.lookup(:database_store))
	end

	Application.register :database_store do
	# code to initialize database storage for session
	end

	# inject session service into every action

	# Based upon Rack-flash:
	# https://github.com/nakajima/rack-flash

	def self.included(action)
	action.class_eval do
	# We rely on features provided by Lotus::Action::Session so let's include
	# it right here
	include Lotus::Action::Session

	class Logger
	def info(*args)
	puts(*args)
	end
	end

	class Auditor
	def log(action)
	puts "Following action was performed: #{action}"
	end

	class Create
	include Lotus::Action
	expose :booking, :errors

	def call(params)
	@booking = Booking.new

	# BookingForm validates datetime entered and converts the values into a single Time object
	form = BookingForm.new(booking)
	# Syncs the form values to the entity
