#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

$(document).ready(function() {
    $("button.remove").on('click', function(e){
        e.preventDefault();
        if ( ! confirm('Are you sure?')) {
            return false;
        }
        var action = $(this).data("action");
        var parent = $(this).parent();
        $.ajax({
            type: 'delete',

1. Voting

Each voter can vote in zero or more referenda. Each referendum has one or more questions, and each question is a yes/no vote. Write the simplest normalized schema to describe this in generic SQL statements or as an entity-relationship diagram. Point out where the indexes would be if you want to quickly know the results of a given referendum question, but you never expect to query a single voter's voting record.

2. Availability on AWS

Your client plans to host their web application on AWS. When would you advise (a) deployment in a single availability zone, (b) deployment in multiple availability zones in a single region (c) deployment in multiple regions? What operational difficulty or complexity, if any, is added as you go from (a) to (b) to (c)?

Load lib files in production (Rails 5)

If you have your code defined in classes in lib/ folder you may have problems to load that code in production.

Autoloading is disabled in the production environment by default because of thread safety.

Change config/application.rb:

    config.autoload_paths << Rails.root.join("lib")
 config.eager_load_paths &lt;&lt; Rails.root.join("lib")
