This course teaches the basics of Rails development. Rails is a framework for developing database enabled web applications quickly and easily. In this course, we assume that you already have a knowledge of Ruby.
The course is divided into three units. In unit 1, we'll look at how Rails is organized. We'll talk about the Model / View / Controller design pattern and how Rails implements it, and how to create a very simple “Hello world” application in Rails. We'll also look at creating an application using a scaffold, and create a simple app to track contacts and phone numbers.
Unit 2 will dive deeper into Rails, and create our contacts app from scratch, starting with a simple controller and view Along the way, we'll learn about resources and creating a model for the app, as well as view to add a contact and show the most recently added contact.
I hope you enjoy the course as much as I've enjoyed writing it.
