Nairuby and Moringa School welcome you to join us for our One-day Ruby Workshop!

You’ve got a head full of ideas when it comes to creating a web app, but where do you start? In this Ruby workshop, you’ll learn HTML, Rails, and GIT basics that will get you moving the right direction in your app development process. In this workshop, you will learn the basics of programming in Ruby - enough to play around with arrays, hashes, control structures, and methods. You will also be able to build and deploy a simple Rails app (“Twitter clone”) to Heroku.

If you'd like to pay via M-Pesa, please send Ksh. 1,500 to 0710199526 and send us your email at

  • Build a simple object-oriented Ruby program
  • Differentiate arrays and hashes
  • Apply loops to manipulate collections
  • Create and implement custom methods and classes
  • Explain the MVC structure and differentiate between models, views, and controllers.
  • Build a simple Rails app from scratch


Introduction to Ruby

  • Strings
  • Arrays and hashes
  • Control flows
  • Variables
  • Methods
  • Classes
  • Build a simple object-oriented Ruby program

Introduction to Ruby on Rails

This is just a rough guideline, not a mandate. Some steps you'll go over and some you'll go under. It'll all work out by the end of the day.


Build a simple project (app from scratch and deploy it on Heroku)


We're going to be working with:

  • Ruby 2.1 or 2.2 installed via RVM (Mac or Linux) or RailsInstaller (Windows)
  • Rails 4.2.x
  • Bundler
  • SQLite
  • The text editor of your choice[1] [2]

Everything should be set up the night before during our install-fest. Please ensure you have everything working before you show up for RailsBridge on Saturday.

You can verify that you have everything working by trying this out in your terminal:

$ irb
>> 1 + 2
=> 3
>> require "active_support"
=> true
>> exit

If you can do that, you are good to go!

Prereqs & Preparation

Students should be knowledgeable and comfortable in the general ways the World Wide Web works.

No pre-reqs but some pre-course work in the command line and git would be good if you are not familiar. Ideally, understand how to navigate to a folder using the command line.

Review these resources before class:


Laptop preferably a Mac but PCs welcomed.

Text editor, such as Sublime Text:

Working Effectively and Efficiently

We highly recommend you do the following:

  • Bring up your terminal and open 2 tabs:

One is for regular terminal stuffs

One will be for IRB (a.k.a. Rails console). We'll explain later.

  • Open your browser fresh or hide any windows you already have open.

Bring up one window with two tabs

One for this content

One for interacting with your app.

  • Open your text editor and do not ever close it. We're not quitters.
  • Hide all extra applications. Turn off Twitter, IM, and all other distractions.

By minimizing the number of things you interact with, you reduce the amount of time spent switching between them and the context lost as you work through the lessons. Having 50 tabs open in your web browser gets confusing and wastes time.
