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. In this course, we will explore how to build web applications with the Ruby on Rails web application framework, which is geared towards rapid prototyping. Yes, that means building quickly! At the conclusion of this course, you will be able to build a meaningful web application and deploy it to the “cloud” using a Heroku PaaS (Platform as a Service). Best of all, it will almost feel effortless… Really! “But wait”, you will say, “there is no way that we can build a useful application if there is no database involved. You need the data for an application to be useful.” Great point! But what if… instead of getting the data from the database, we get it from the internet by tapping into one of the web services out there that readily provides data needed by our application? “Ok, but that’s probably very complicated”, you will say. Take this course and you will be pleasantly surprised at just how easy it is!...

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,

One of the most challenging things I've ever done.\n\nThe 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

This course gives a very solid foundation, and it is highly recommended for those who want to get a firm grip on the Ruby on Rails development techniques. I am personally impressed with how test driven development is seamlessly integrated into the course material.

The name of the course says "introduction" but the assignments of the course make the learning of Ruby on Rails a complete rewarding experience. I have been practiced self learning on Ruby on Rails and did not go very far. This course consolidate my past experience such as environment setup (DOS, git, devkit, SSL), OOP, and RESTful API to get data from other sites.

Kalman Hazins is a great instructor. His lessons are well prepared, no fluff, to the point. As a bonus I can imagine getting taught by Christpher Walkin.

In only just three weeks time this course provided me enough knowledge and guidance that I felt confident enough to start creating my own simple Rails applications. I'm enrolled now in the second course of this specialization to continue my journey on becoming a better Rails developer.

Very good course. Covers a lot of Ruby and a little of Rails. It was possible to see how simple is to put a working site on air.

Well designed, well delivered, with good pedagogy. Prof Hazins did a great job in making the material understandable, but yet challenging.

I learned a lot about Ruby/Rails/Web Devepoment from this one course. Look forward to the others.

If you have some background programming in another language, and some familiarity with HTML/CSS, this course does a fantastic job introducing both Ruby and Rails. The first week walks you through machine and environment setup, the second walks through the basics of the Ruby programming language, and the third walks through using the Rails framework to develop simple websites in Ruby. All the lessons are laid out clearly with solid examples.

That said, this is not a beginner course. It really only spends a week covering how to program in Ruby, and Ruby has some quirks that make it a challenging first language. If you're brand new to programming, do yourself a favor and take an introductory course first.

You can learn a lot, but I do not think it is useful for beginners.

The first Web Development course I enjoyed - instructions were clear, tasks were not that trivial and above all - practical.
