How To Build a Ruby on Rails Application on Ubuntu 22.04

Introduction

Rails is a web application framework written in Ruby. It takes an opinionated approach to application development, assuming that set conventions best serve developers where there is a common goal. Rails therefore offers conventions for handling routing, stateful data, asset management, and more to provide the baseline functionality that most web applications need.

Rails follows the model-view-controller (MVC) architectural pattern, which separates an application’s logic, located in models, from the routing and presentation of application information. This organizational structure — along with other conventions that allow developers to extract code into helpers and partials — ensures that application code isn’t repeated unnecessarily.

In this tutorial, you will build a Rails application that enables users to post information about sharks and their behavior. This project will serve as a starting point for future application development.
