In this course, David Morales, a web developer and technical instructor, gives you the tools and knowledge that you need to start developing with the Ruby on Rails web framework, using a GitHub Codespaces environment. Get an overview of the development environment, then create a simple application. Learn how to work with databases, migrations, routes, controllers, and the asset pipeline. Plus, go over image management with Active Storage, code reuse techniques, and using Hotwire to add reactivity without writing javascript.
The best way to learn a language is to use it in practice. That’s why this course is integrated with GitHub Codespaces, an instant cloud developer environment that offers all the functionality of your favorite IDE without the need for any local machine setup. With GitHub Codespaces, you can get hands-on practice from any machine, at any time—all while using a tool that you’ll likely encounter in the workplace. Check out the “Using GitHub Codespaces with this course” video to learn how to get started.
