How to Learn Ruby on Rails in 2018, the Ultimate Guide
But, if you want to learn Ruby, you can checkout out my other post on How To Learn Ruby.
What is Ruby on Rails
Ruby on Rails is a web framework, developed on top of the Ruby language that focuses on building web applications quickly, and with small teams. It does that by focusing on conventions over configuration (or great defaults).
That means you can skip on the repetitive parts of your application, and focus your attention on the parts that make a difference.
For example, most web applications have users and need things like registration, login, logout, remember me, and password reset functionality. You can have all that in Rails by writing a single line of code.
Imagine having that kind of pre-built functionality for all the different areas of your application. How much time woult something like that save you?
And it’s not like you get something pre-built that you can’t customize to your liking. You can customize everything as long as you’re willing to trade your time for it.
Why learn web development with Rails in 2018
While Ruby on Rails was first released in 2004, and a lot has happened since then, it’s still relevant in 2018.
Ruby on Rails was built with a specific goal in mind. To make websites. That is at its core. So, everything it does is to optimize that process.
However, there are a few specific reasons why you might want to choose Rails over other frameworks.
If there is one area where Rails raises above its competition, it has to be this one.
You can move extremely fast with Rails. You can get from idea to implementation in a matter of days, or weeks (of course it depends on the complexity of your idea).
Building Minimum Viable Products (MVPs)
If you’re in the early stages of trying to find product/market fit, or you want to ship something to your customers, you can do that very fast.
Check out these other articles if building an MVP is something you’re looking for.
Finding a well-paying job
If all you want is to get hired and earn a good salary, Rails is a good way to make a living.
The TIOBE index places Ruby in the top 15 technologies.
Salaries are high, and there is still demand for Rails developers (check out Demand for Ruby on Rails is Still Huge for an interesting analysis).
There’s a vast (and growing) community of developers contributing to the Rails ecosystem that you can leverage for building your applications.
Taking a quick look at StackOverflow, there are 294652 total questions (and 378 this week) for Rails. Plus another 196711 for Ruby. This is important, it means you can get help really quickly when you get stuck on a problem.
Another useful thing is the number of libraries you can use in your code, and Ruby has about 9495 of them.
If all else fails
If none of those reasons make Rails a compelling technology for you, it will at the least teach you a few useful concepts. Here are a few of them.
- Test Driven Development (TDD)
- Model View Controller (MVC) pattern
- Don’t Repeat Yourself (DRY)
- Representational State Transfer (REST)
What is Ruby on Rails bad at
As previously mentioned, one of the framework’s strengths is rapid development.
However, from my experience, working with large Rails projects, I can tell you that there’s one thing that all large projects have in common. And that is deceleration. As projects get larger, development gets slower and slower.
If that is something that happens to you or your team, you might want to read Is Your Rails Team Slowing Down? Here’s Why, And What You Can Do About It.
This comes very often a surprise for managers because they chose Rails as a high-speed development framework.
Of course, this is not a problem with the language. It’s more of a problem with how it’s perceived.
While Rails allows you to move fast, it doesn’t mean you’ll get scaling as a bonus. You need to build that yourself.
What is Ruby on Rails used for
One of the hardest problems startups have is finding product/market fit. In other words, if people don’t want your product, you don’t have a product (you don’t even have a business).
So what Rails has managed to achieve is to help startups find product/market fit relatively quickly and with a relatively small team (very often just one developer).
Examples of Ruby on Rails websites
There are a few companies and projects that you might recognize, and not realize they were built with Rails. Here are some of the most popular ones.

How do I learn web development with Ruby on Rails?
I remember when I first started, there weren’t too many tutorials out there. I relied mostly on Railscasts, but that website hasn’t been updated in a while.
So here is my take on how you should start learning Ruby on Rails. This also applies to most things you learn, not just Rails.
1. Choose a project with deadlines
This could be either a new job as a junior Rails developer, or building a web application for a client if you’re freelancing, or even a personal customer-facing project.
It doesn’t matter what you’re building as long as it has a powerful motivational element to it. The most powerful motivator I know is a deadline.
A deadline will eradicate procrastination from your learning process, and it will skyrocket your learning speed.
2. Do what works
You don’t have to write perfect code from day one. You can’t, even if you try.
All you need to do is write code that works, and make sure someone reviews it.
This is very powerful because the best way to learn a new concept is to associate that new concept with something you already know. So when someone reviews what you already know, you get to link it to what they tell you about your code, with the new concept.
3. Improve your code
Over time, all these little course corrections add up, and that’s how you become a good Rails developer. You learn everything in small increments and in such a way that makes sense for you at the level you’re currently at.
This process has worked wonders for me, and I hope it will transform the way you learn.
What is the best Ruby on Rails tutorial for beginners?
The real answer to this question is: it depends on the how you learn best. If you prefer books, or video courses, or just building stuff and copy-pasting solutions.
There are tons of resources out there for learning Rails, but I’m going to list two of my favorites as top picks.
The Agile Web Development with Rails book is also highly recommended.
Note that these two are not free. However, there are a few free ones you should check out.
Where to learn Ruby on Rails free
The official Blog in 15 minutes, presented by the author of Rails himself is an excellent place to start.
The official Ruby on Rails guides are also pretty good if you find the format easy to read.
What is the best Ruby on Rails book for beginners
There’s the Ruby on Rails Tutorial book by Michael Hartl that you can read for free online.
It teaches you the basics from install to deploy.
What are the best Ruby on Rails free courses
This is another fun way to learn Rails. You get to learn Rails by building projects.
Coursera has a few courses for learning Rails.
Learn Ruby by playing a game. It’s an interesting way to learn.
Paid video courses
This one has got to be the most popular course I’ve seen on Udemy (47,361 students), and it’s got a 4.4 out of 5-star rating.
With 8,192 students enrolled and a rating of 4.6 out of 5, this course seems to be a great value for $9.99.
A few parts of the course are free, but most of it is paid.
Books and videos tutorials for learning Rails
Upcase focuses on more advanced topics, so if you’re really new to Rails, you might want to put this one aside for now.
Gary Bernhardt’s take on Ruby and in general is one of the best in the industry. And the screencasts he’s made are really eye-opening.
As mentioned previously, the book by Sam Ruby and David Bryant Copeland is focused on getting you started with Rails. It has everything you need to get going.
This book by Michael Hartl is free to read online.

Here are some of the more popular editors (and IDE) for Ruby on Rails.
Emacs (free) - Emacs is just as good as Vim, but sadly it’s got the same learning curve as Vim does.
Atom (free) - Atom is a great looking editor, but for my taste it’s way too slow.
Visual Studio Code (free) - A nice code editor from Microsoft.
SublimeText 3 (paid) - I like SublimeText for its speed. It feels responsive like an editor should.
The RubyMine IDE (paid) - If you like IDEs, RubyMine from JetBrains might be the best one you can find for working with Rails.
