  1. The Birth and Evolution of Ruby on Rails Ruby, the programming language behind Ruby on Rails, was created by Yukihiro Matsumoto in the mid-1990s. It was designed to prioritize developer happiness and productivity. Matsumoto wanted to create a language that was both elegant and practical, and that's how Ruby was born. Rails, on the other hand, was created by David Heinemeier Hansson in 2004 while developing the Basecamp project. Rails was extracted from Basecamp and open-sourced, quickly gaining popularity due to its productivity-enhancing features. 1.2 The Rails Philosophy Ruby on Rails is guided by several core principles, commonly referred to as the "Rails Philosophy." These Ruby Rails Web Development principles include DRY (Don't Repeat Yourself), Convention over Configuration, and the pursuit of beautiful code. We'll explore how these principles shape the development process. Chapter 2: Getting Started with Ruby on Rails

  2. 2.1 Installation and Setup To embark on your Ruby on Rails journey, you'll need to install the Ruby programming language and Rails framework. We'll walk you through the installation process and get you ready for your first Rails application. 2.2 Building Your First Rails Application In this section, we will guide you through creating a simple Rails application. You'll learn how to generate controllers, models, views, and routes, and see how the MVC (Model-View-Controller) architecture is applied in practice. Chapter 3: The MVC Architecture in Ruby on Rails 3.1 ModelThe Model in Rails represents the data of the application. You'll learn how to define models, create database tables, and interact with the database using ActiveRecord, Rails' built-in ORM (Object-Relational Mapping) tool. 3.2 View Views in Rails are responsible for presenting data to the user. We'll explore how to create dynamic and interactive views using Rails' template system and the use of layouts and partials. 3.3 Controller The Controller is the intermediary between the Model and the View. We'll discuss how controllers handle incoming requests, interact with the model, and render the appropriate view to the user. Chapter 4: Diving Deeper into Rails 4.1 Routing We'll take a closer look at how routing works in Rails, and how it maps incoming requests to controller actions.
