Learn object-oriented programming using the Ruby language so you can write your own Ruby programs and jump right into Ruby on Rails.
Start learning Ruby programming today and get ready for Ruby on Rails!
You'll discover how to build your own Ruby program from beginning to end, design Ruby classes, incorporate Ruby principles and techniques in your design, write your own Ruby gem, and make sense of the “magic” of Rails. All of the topics and syntax in this course work seamlessly with both Ruby 2.0 and 1.9.
“If I were going to learn Ruby from scratch today, this is how I would do it!” Chad Fowler, Author of Rails Recipes and The Passionate Programmer
“The course is outstanding! The best I've ever taken. Rails is so much less mysterious now that I'm learning Ruby the right way.” Tony Barone
Learn the Pragmatic Way
Build a complete, tested Ruby program from scratch. In this course we follow a step-by-step, project-based approach to learning how to write well-designed Ruby programs. By building a real project with real code from scratch, you'll come away knowing how to write your own Ruby programs and have a deeper understanding of both the "how" and the "why".
Ruby Programming Environment Ruby has a rich set of programming tools and libraries. Setting up your working environment and using it effectively is the first step toward becoming a productive Ruby programmer.
- Installing Ruby on your favorite operating system
- Running Ruby using the interactive Ruby shell (irb) and writing Ruby program files
- Using Ruby's documentation system to get help
- Installing external Ruby libraries using RubyGems
- Troubleshooting common problems
Organizing Ruby Code Once you've conceptually organized your program into classes and modules, you'll want to further organize it for reuse, unit testing, and distribution.
- Creating a Ruby project structure
- Separating source files for easier reuse and testing
- Namespacing to avoid naming clashes
Ruby Language Constructs If you're already programming in another OO language, some of Ruby's constructs may feel familiar. But Ruby has some pleasant surprises, as well. Topics include:
- Expressions and variables
- Numbers, string, and symbols
- Loops and conditional expressions
- Arrays and hashes
- Classes, modules, and structs
Input/Output Ruby has great support for interacting with the external world, whether it be through files, an interactive console, command-line input, or even the web. You'll need some form of I/O in your application, but once you learn Ruby's I/O libraries you might also start rewriting one-off scripts in Ruby, too. Topics include:
- Reading data from files
- Writing data to files
- Creating an interactive console prompt
- Handling command-line input
Object-Oriented Programming Ruby is an object-oriented programming language. It's also a dynamic language. But what does that really mean and how does it change the way you write programs? We'll show you! Topics include:
- Using built-in Ruby classes
- Defining your own classes with state and behavior
- Creating unique objects
- Telling objects what to do by calling methods
- Modeling class-level inheritance relationships
- Sharing code with mixins
Unit Testing The Ruby community places a high value on testing, and it's for good reason. Testing gives you the courage to make changes, and as a result you're more productive. Topics include:
- Writing and running unit tests with RSpec
- Test-driven development and the red-green-refactor cycle
- Stubbing methods to control tests
- Refactoring code, safely!
Object-Oriented Design Principles Defining classes and using objects is a good start, but along the way you'll also need to consider the overall design of your program. Can you make changes without ripple effects? Can you easily test the code? Can someone else use the code as a library? Topics include:
- Separation of concerns
- Don't Repeat Yourself
- Tell, Don't Ask
Distribution Finally, you'll likely want to package up your Ruby code and share it with your friends… or the world! Topics include:
- Conforming to RubyGems conventions
- Writing a GemSpec
- Building a RubyGem
- Publishing a RubyGem to a public server
Blocks and Iterators Blocks are a fundamental and powerful aspect of the Ruby language. You'll find blocks used throughout good Ruby programs. And many of the methods found in the Ruby standard library itself take blocks. To be an effective Ruby programmer you must master blocks! Topics include:
- Calling built-in methods that take blocks
- Writing your own methods that yield to blocks
- Implementing custom iterators
- Effectively using blocks in your programs
Ruby Programming Idioms Writing a Ruby program that works isn't always the same as writing a good Ruby program. To master Ruby—to write compact, readable, and flexible Ruby programs—requires that you learn the idioms and culture of the Ruby community. That's what this course is all about: becoming truly fluent in Ruby!

“Your course has been one of the most amazing experiences I have ever had learning coding. I'm absolutely loving it. The speed of the course is perfect. The tone of the videos is just right, and the workbooks are great.” Ross Curzon-Butler
“I've been developing Ruby on Rails websites and apps for two years. This course gave me dozens and dozens of 'Ah-ha!' moments with regards to what is actually going on in my Rails apps. My confidence for building new Rails apps and refactoring my existing apps has increased tremendously.” Chip Ashby
“First of all, Mike and Nicole were fantastic! Everything was explained clearly and step by step (and it really felt like they were explaining things directly to me). I was trying to learn Ruby on my own through various online tutorials, but they only offered bits of information that I did not know how to put together. This course was structured very well so I always learned things in context.” Marcin Drozd
“I have tried many things over the past year and nothing clicked. But your class really got me excited about Ruby. The best thing about your class is that you taught software design principles, not just how to run a loop or assign a variable. That is what made everything click and made it practical. You have really helped me further my goals!” Paul Haddad
“I think this was the best course I've ever seen online. It felt really well structured and seemed to give me just the right amount of knowledge from lesson to lesson.” Antonio Borges Rosado
“The course is great! It really teaches you how to think like a Ruby developer.” Matt Halliday
“I've been trying to add Ruby and Rails to my tool belt for the past 3 years, and have tried a handful of books and online courses. But, I've never been able to stick with any until I tried your Ruby course. I'm loving the course!” Jeremy Kratz
