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,

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.

Old versions of Ruby and Rails make the exercises a chore.

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

Outdated. Should be kept current.

I think this was a great course. The various issues with versions of ruby, rails, gems, operating systems, etc was frustrating at times but at the same time very much "real world" as I learned how to reflect about possible solutions and use online resources to sleuth the problems. Looking forward to the next courses and becoming more comfortable with rails.

This course is peach. Amazingly coached by Prof. Hazins. I learnt a great deal about web development, ruby language, the Rails framework, version controlling using GIt, using cloud based deployment service heroku and in general it increased my knowledge about the internet on the whole ;)

Versions of packages are a bit old, but overall it was the best introduction to Ruby on Rails compared to other resources that I have tried! I have experience in Java, so the part that he talked about the difference from Java was also helpful.
