Free online courseRuby on Rails for Beginners: Build a To-Do App, CRUD and Deploy

Course Description

Turn an idea into a working web application with Ruby on Rails, one of the most practical frameworks for building full-featured products fast. In this beginner-friendly course, you will set up your environment, create a brand-new Rails app, and develop a clean, usable to-do tool that mirrors how real web projects are built. If you are coming from HTML/CSS or another language, Rails offers a clear structure and conventions that make it easier to understand how the parts of a modern app fit together.

You will experience the full workflow of building an application end-to-end: generating a project with Rails, creating resources that support create, read, update, and delete functionality, and wiring pages together through routing and controller actions. Along the way, you will work with models and the database through Active Record, learning how data is represented, queried, and updated in a way that stays readable as the app grows. You will also connect related data so your to-dos can belong to projects, a foundational skill for building anything beyond a single table.

To help your app feel like a real product, you will enhance the interface with Tailwind CSS, learning how to improve layout, spacing, and visual clarity without getting lost in complicated styling setups. Finally, you will take the important step many beginners skip: deploying your Rails app so it runs outside your local machine. By the end, you will understand the core Rails components working together, feel comfortable navigating a typical Rails codebase, and have a small portfolio-ready project that demonstrates practical web development skills.
