Problem

A user's true identity or email address must be verified before they are given full access to your application.

Solution

The system sends an email to the user's email address containing a unique, personalized url. Visiting the url in a browser provides sufficient identity verification, since the url could only have been known to the person who received the email.

	# Given these models:
	#
	# Customer
	# - name: string
	#
	# Product
	# - price: integer
	#
	# Order
	# - customer_id: integer

	# you'd obviously have more settings somewhere
	set :scm, :git
	set :repository, "[email protected]:defunkt/github.git"
	set :branch, "origin/master"
	set :migrate_target, :current # this tells capistrano where to run the migration. otherwise it would try to use the latest release directory (/path/to/app/releases/2012XXXXXXXXX)
	set :use_sudo, false
	set :ssh_options, {:forward_agent => true} # so you can checkout the git repo without giving the server access to the repo
	set :rails_env, 'production'

	# These are here to override the defaults by cap

	# Python 3.4

	# A nice class
	class Person:
	def __init__(self, name):
	self.name = name


	# A nice function
	def speak():

	# Add this file to your config/initializers directory.

	# Then you can do things like:
	#
	# Product[5] instead of Product.find_by(id: 5)
	# Product.sample to pull a random Product row
	# Product.sample(3) to pull three random Product rows (but they will be consecutive)
	#
	# Biggest part: automatic associations!
