About the Course

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

While the description for this program states that you do not need to have any experience with Ruby in order to take this Ruby on Rails program, that is entirely false. You have to have not only experience working with Ruby, but also working without any instruction. The professor does not explain anything regarding utilizing the IDE environment, working with bootstrap files, how to implement code, or how to write code. I had to consult GitHub and Stackoverflow forums for assistance on most of the assignments and guess on everything else. I spent 4 days working on the final assignment due to faulty bootstrap files provided without any help from course professors. This is by far the worst course I have taken with Coursera.

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.
