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

This course is really well done (structure, material, examples, tests etc.). It is especially useful for people who already know some programming language. It provides a complete representation of good application (git, tests (rspec + Capybara + phantomjs) , heroku, using some API etc).

The course contains only 3 modules, but this modules contains essential information for junior RoR developer.

Also I'd recommend to read "Head First Ruby" during the course. The course and the book helped me to dive into ruby during one week.

It is an excellent introduction to Rails and the best part is the learning from assignments at end of each week and the final project. It is a well thought out course.

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.

Guys, Apart form the incredible quality of course content, which is in itself an privilege as I got this course on financial aid, the best and by far the most awesome thing about this course is there are intentional pitfalls designed in the challenges itself. The challenges are written to give you hints on what is necessary and this makes you go through the documentation of the respective components which is a super awesome thing. Would recommend it if anyone is excited to learn Ruby on Rails and thanks a tonne Coursera for this privilege.

Nice course, lots of information. I liked the level not being too low or too high. The level is nice for if you have programming experience, but have no experience with developing web applications.

Cheers, Ben
