Did you ever want to build a web application? Perhaps you even started down that path in a language like Java or C#, when you realized that there was so much “climbing the mountain” that you had to do? Maybe you have heard about web services being all the rage, but thought they were too complicated to integrate into your web application. Or maybe you wondered how deploying web applications to the cloud works, but there was too much to set up just to get going.

Welcome and Setting Up the Development Environment
In this module, we will install software required to develop Ruby on Rails applications. We will also demonstrate the use of a popular Ruby on Rails editor called “Sublime Text”. We will finish the module by familiarizing ourselves with a version control system called “Git” that will be used later in the course to submit assignments, as well as to deploy Ruby on Rails applications to a PaaS (platform as a service) called “Heroku”.

Introduction to Ruby on Rails
In this module, we will become familiar with core concepts behind Ruby on Rails, such as CoC (Convention Over Configuration) and MVC (Model-View-Controller). <p>We will then learn about consuming JSON API with HTTParty, a Ruby gem. We will then integrate this ability to consume JSON API to serve as the data layer for our Rails application.</p>Finally, to conclude this module we will deploy the application to Heroku and write a unit test that will verify the desired functionality.

Meilleurs avis pour RUBY ON RAILS: AN INTRODUCTION
par HM30 sept. 2017
I have played around with Ruby on Rails before but this course really helped me understand the nots and bolts. It is worth replicating all the examples shown in the videos to get a good understanding,
par JM21 janv. 2019
I like the content but definitely the submission and assessment should improve. The main problem is the version used in the videos is already quite old and difficult to get that version nowadays
par GC6 août 2016
One of the most challenging things I've ever done. The course goes from zero to web deploy in 3 weeks and there are more to enjoy, discover and learn....\n\nTry it, I't's a no-return voyage
par MB1 mai 2016
Good intro, nice to mix in the various concepts that I will be working with as well (Heroku, Git, etc.). Also appreciated the Java comparisons since I have been working in Java for 15 years.
