#Simple Authentication with Bcrypt

This tutorial is for adding authentication to a vanilla Ruby on Rails app using Bcrypt and has_secure_password.

The steps below are based on Ryan Bates's approach from Railscast #250 Authentication from Scratch (revised).

You can see the final source code here: repo. I began with a stock rails app using rails new gif_vault

##Steps

Include Weather Icons in your app: https://github.com/erikflowers/weather-icons
Include the below JSON in your application, for example purposes, lets assume it's a global named weatherIcons.
Make a request to OpenWeatherMap:

req = $.getJSON('http://api.openweathermap.org/data/2.5/weather?q=London,uk&callback=?');

	=Navigating=
	visit('/projects')
	visit(post_comments_path(post))

	=Clicking links and buttons=
	click_link('id-of-link')
	click_link('Link Text')
	click_button('Save')
	click('Link Text') # Click either a link or a button
	click('Button Value')

	module BinaryTree
	class Node
	attr_reader :word, :count, :left, :right

	include Enumerable

	def initialize(word)
	@word, @count = word, 1
	end

	require 'rubygems'
	require 'yaml'

	# A demonstration of YAML anchors, references and handling of nested values
	# For more info, see:
	# http://atechie.net/2009/07/merging-hashes-in-yaml-conf-files/

	stooges = YAML::load( File.read('stooges.yml') )
	# => {
	# "default" => {

	t = 236 # seconds
	Time.at(t).utc.strftime("%H:%M:%S")
	=> "00:03:56"

	# update application.rb

	def initialize(app)
	@app = app
	end

	def call(env)
