To configure Rails to rotate your log files while in the development and test environments, add the following to your development.rb and test.rb files found within /config/environments/

# Keeps the Last 5 logfiles which are rotated at every 5MB
config.logger = Logger.new("#{Rails.root}/log/#{ENV['RAILS_ENV']}.log", 5, 5242880)

Note: I had issues with setting up my Facebook app so authentication would work. I'd receive the error at the bottom, and it took me a while to figure out what was wrong

Here are the steps I took:

• Go to http://developers.facebook.com/, create, and setup your app
• When inside the dashboard, click "Settings"
• Click "Add Platform"
• Choose website (for authentication via the web app)
• Add http://localhost:3000/ as "Site URL" (and "Mobile URL" if necessary)
• Add localhost to "App Domains" above

#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
