Free online course Ruby on Rails

About the free online course

Learn how to turn an idea into a working web application using Ruby on Rails, one of the most productive frameworks for building modern sites and internal tools. This free online course guides you from the first steps of understanding what Rails is to confidently creating, improving, and deploying an application you can share with others. Along the way, you will practice the habits that make Rails developers effective: working with conventions, keeping code organized, and moving quickly from prototype to production.

You will start by setting up a complete development environment on Windows or Linux, learning what each tool is for and how they fit together. With a clean setup in place, you will create a sample Rails app and build comfort with the command line, Interactive Ruby (IRB), and the Ruby language basics that power everyday Rails work. That foundation helps you read code more easily, avoid common mistakes, and make changes with intention as your project grows.

From there, you will experience the Rails way of building features: structured applications with controllers, views, routes, and models that communicate clearly. You will connect your app to a database, plan data thoughtfully, and use associations so your information reflects real-world relationships. As you move through reading, creating, editing, and updating records, you will see how dynamic pages come to life and how clean patterns keep development efficient.

The course also strengthens professional workflow skills. You will use Git for version control and learn how deployments work by pushing your application to Heroku, including handling PostgreSQL in a cloud environment and keeping your database changes in sync through migrations. You will also improve the user experience by integrating HTML/CSS layouts, building navigation and static pages, and rendering reusable partials that keep views maintainable.

Finally, you will be introduced to admin tooling, search and comment relationships, and the importance of testing for stable releases. By the end, you will have a practical, end-to-end understanding of Rails development and the confidence to continue building real applications for a portfolio, a team, or your next job opportunity.
