Ruby on Rails for Beginners: A Comprehensive Overview and Guide to Developer Growth

Ruby on Rails, commonly referred to as Rails, is a popular and powerful web application framework written in Ruby programming language. Its simplicity, efficiency, and elegant syntax have gained significant traction among developers.

Whether you're a beginner or an experienced programmer looking to dive into web development, Ruby on Rails is an excellent choice.

In this blog post, I’ll provide a comprehensive overview of Ruby on Rails, its key features, and why it's worth learning and leveraging.

Heads up, this article is always a work and progress and will be updated as the framework and resources are available. Check back often!

What is Ruby on Rails?

Ruby on Rails, often called Rails, is an open-source web application framework that follows the Model-View-Controller (MVC) architectural pattern. It was created by David Heinemeier Hansson and released in 2004.

Rails aims to simplify the development process by emphasizing convention over configuration, providing sensible default settings and guidelines, and reducing the need for explicit programming decisions.

The Key Features of Ruby on Rails

Convention over Configuration

Rails follows the "Convention over Configuration" principle, which provides sensible defaults and guidelines, reducing the amount of repetitive code and making development faster and more straightforward.

MVC Architecture

Rails follows the Model-View-Controller (MVC) architectural pattern, which separates the application into three interconnected components: the Model (handles data and business logic), the View (presents the data to the user), and the Controller (handles user interactions and requests).

Rapid Development

Rails is renowned for its ability to enable rapid development. It offers a wide range of built-in tools and libraries that streamline everyday tasks, such as database migrations, testing, and scaffolding, allowing developers to focus on implementing unique features.


ActiveRecord is an essential component of Rails that provides an Object-Relational Mapping (ORM) layer. It simplifies database interactions by mapping database tables to Ruby objects and providing a rich set of methods for querying and manipulating data.

Gems and Plugins

Ruby on Rails has a vast ecosystem of gems and plugins that extend its functionality. Gems are prepackaged libraries that can be easily integrated into Rails applications, while plugins offer additional functionality and can be easily shared among Rails projects.

Why Learn Ruby on Rails?

It’s beginner-friendly

Ruby on Rails has a gentle learning curve, making it an ideal choice for beginners. Its syntax is clean and readable, which makes the code easier to understand and maintain. Additionally, Rails' convention-over-configuration approach provides structure and guidelines, reducing decision fatigue for new developers. Conventions are easier to follow when starting, so this leads to initially following the “Rails way,” but as you get more comfortable gives you enough confidence to break outside those “rails” when necessary.

Productivity and Efficiency

With Rails' emphasis on convention and its extensive collection of built-in tools, developers can build web applications quickly and efficiently. Rails' ability to generate boilerplate code and automate repetitive tasks saves time and effort, allowing developers to focus on implementing unique features. You don’t need a team to build an app anymore. One developer could build a fully featured application on many devices.

Active Community and Vast Resources

Ruby on Rails has a vibrant and supportive community that actively contributes to its growth and development. Many contributors to Rails work at brands you’ve heard of and make the framework even more powerful.

You'll find numerous online resources, tutorials, and forums to help you learn and troubleshoot any issues you encounter. The community's enthusiasm and willingness to share knowledge make learning Rails an excellent experience.

Job Opportunities

Ruby on Rails remains in high demand, and many startups and established companies use Rails to power their web applications. Many job offerings of late cater to seasoned Rails developers, but there has been a resurgence of the framework lately, which could bring forth more junior and intermediate roles.

By learning Rails, you open doors to exciting job opportunities in web development. Additionally, Rails' emphasis on best practices and code quality will enhance your programming skills, making you a valuable asset to any development team.

Why not use Rails?

If you don’t like opinionated conventions or prefer to build your services, adapters, and tools, Rails might not be for you. Much of the framework is full-stack, minus a few features like authentication. For some, this is the main reason to use Rails; for others, it's a reason to steer clear.

Ultimately, I’d recommend trying it out and seeing for yourself. Coming from the PHP world, I’ve found the developer experience and general productivity boost Rails offers to be a massive game changer in how I approach building and designing software.

Where do I start when it comes to learning Ruby on Rails?

To get started with Ruby on Rails, you can take a DIY approach like I did or lean on those who make it easier to get up to speed fast.

For those that value time more and don’t have enough to commit, I recommend a course, boot camp, or following a series of YouTube videos to allow you to hit the ground running.

For the DIYers

Install Ruby

Visit the official Ruby website and download the latest stable version of Ruby. Installation instructions are provided for different operating systems. Most developers use some Ruby version manager to make this process less chore.

Install Rails

Once you install Ruby, open a terminal (I use iTerm2) and run the following command to install Rails: gem install rails. This will install the latest version of Rails on your system.

Create a New Rails Application

After installing Rails, create a new Rails application using the command rails new your_app_name. This will generate a basic Rails application structure.

Explore and Learn

Dive into the Rails documentation, tutorials, and online resources to familiarize yourself with the framework. Start by understanding the MVC architecture, routing, ActiveRecord, and basic CRUD operations.

I have many videos and articles on this site. There are also good resources out there. Here are a few I’ve compiled:
