The Ruby on Rails Tutorial: Learn Web Development With Rails, 4th edition

Online Courses

The Ruby on Rails Tutorial LiveLessons, Fourth Edition, is the best-selling complete video training course on web development with Rails, the popular web framework for building dynamic, database-backed web applications. You will learn Rails by example by building a substantial sample application from scratch.

Description

Best-selling author and leading Rails developer Michael Hartl teaches Rails by guiding you through the development of three sample applications of increasing sophistication, focusing on the fundamental techniques in web development needed for virtually any kind of application. The updates to this edition include full compatibility with Rails 5 and numerous new exercises interspersed in each lesson for maximum reinforcement. This indispensable guide provides integrated tutorials not only for Rails, but also for the essential Ruby, HTML, CSS, and SQL skills you need when developing web applications. Hartl explains how each new technique solves a real-world problem, and then he demonstrates it with bite-sized code that’s simple enough to understand, yet useful.

Table of Contents
Lesson 1: From Zero to Deploy
The first lesson teaches you how to set up an integrated development in the cloud, create a first Rails application, and deploy it to production with Git and Heroku.

Lesson 2: A Toy App
In this lesson, you get up and running quickly with a toy application that demonstrates the basic workings of a Rails application with users and short posts. It includes a focus on interacting with the toy app through its URIs (sometimes called URLs) using a web browser. You learn how to generate dynamic web pages using the MVC pattern and structure web applications using the REST architecture.

Lesson 3: Mostly Static Pages
This lesson focuses on developing an industrial-strength sample application that is used throughout the rest of the video. You begin by creating static pages and then move on to adding a little dynamic content. After writing all the code from scratch, you develop the sample app using testing and test-driven development (TDD).

Lesson 4: Rails-Flavored Ruby
In a quick detour from building the sample application, you learn about the Ruby language underlying Rails. The lesson also shares how to include an application stylesheet in the sample application, call methods on strings, manipulate arrays and hashes, and define custom Ruby classes.

Lesson 5: Filling in the Layout
This lesson incorporate Twitter’s Bootstrap framework into the sample application, adds custom styles, and fills in the layout with links to the pages created so far. Topics covered include partials, Rails routes, the asset pipeline, Sass, and refactoring tests using RSpec.

Lesson 6: Modeling Users
This lesson demonstrates how to create a data model for the site users that also stores the data. You learn how to implement data validations and add a secure password to allow login and authentication.

Lesson 7: Sign Up
The development of the sample app continues by giving users the ability to sign up for the site and create a user profile. You also learn how to make a signup form with error messages for invalid submission and implement successful user registration for valid submission.

Lesson 8:
Now that new users can sign up for the site, it's time to give them the ability to log in and log out. In this lesson, you learn how to implement the simplest fully functional login model, which keeps users logged in for one session at a time, automatically expiring the sessions when users close their browsers.

Lesson 9:
In this lesson, you build on the login system from Lesson 8 to add the ability to remember the users' login status even after they close their browsers. You also learn how to automatically remember users, and then how to optionally remember them based on the value of a remember-me checkbox.

Lesson 11:
In Lesson 10, you finished making a basic user resource together with the flexible authentication and authorization system. In this lesson and the next, you learn how to put the finishing touches on this system, starting with an account activation feature that verifies each new user's email address. This will involve creating a new resource, thereby giving you a chance to see further examples of controllers, routing, and database migrations. In the process, you also learn how to send email in Rails, both in development and in production.

Lesson 12:
In this lesson, you learn how to give users the ability to reset their passwords if they forget them. The implementation closely parallels the account activations from Lesson 11, providing yet another example of creating a Rails resource from scratch, as well as a second example of sending email in production.

Lesson 13: User Microposts
This lesson demonstrates how to make a data model for short posts (“microposts”), make a page to show a list of microposts, and implement a web interface to create and delete microposts. We then learn how to upload images and associate them to microposts, including image resizing, format validations, and production deployment using a cloud storage service (S3).

Lesson 14: Following Users
The final lesson completes the core sample application by adding a social layer for users to follow and unfollow other users. You learn how to make a data model between users, give users the capability to follow each other through the web, and create a status feed of the microposts from the users.
