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

It assusmes quite a lot of things about web programming… and the assignments were too complex to just practice what we should learn in an introductory course.

The course hasn't been updated in nearly five years. Third week assignment's grader is broken. Rails 6 is out and this course still suggests Rails 4.2.

Wordy, dirge like. The topic is interesting but the exposition is so boring - the reading of a lecture outline - that I'd rather study on my own 8-(

Awful. Courses are not detailed, Lack of support in the forums, absolutely not helpful for someone who just started studying Ruby on Rails

Horrible. The tests make very little sense, use elements not described in the course and is generally very confusing.

A lot of things (Ruby version controls, PhantomJS installation) from this course don't work on Mac OS X El Capitan.

The material is outdated. The examples don't work and it's frustrating to learn something on legacy mode.

Very narrow course. It clearly shows the difference between MOOC and practical real courses.
