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,

It's a great course for beginners in Rails. Mainly if you get a language like Java (has lot of comparisons)

Excellent MOOC.

Not only the basics of RoR are taught, but also tools from the ecosystem: git, github and others.

Really good course! Covers the introduction in a smart way and show a lot of smart tools. It gives you a important basis for Ruby on Rails with relevant examples and assignments.

There is one point against it, it is difficult. If you are doing it as a weekend relaxed hobby, you really need to love programming. The assignments give you an idea of real life problems but real life problems are not easy.

Anyway, if you want to learn Ruby on Rails in the reality it is a great course for you.

An example of how a course should look like. It has everything you need to learn :

1) good videos

2) good materials

3) a teacher that is active on the forum

4) very well explained projects

5/5 would recommend :D

Going of to listen second part of this specializations.

Very practical, makes easy for the student to go over the installation and configuration hubs, to-the-point introduction to Ruby on Rails. At the end of this course, I was able to write a decent looking web application, develop an understanding of the core concepts, and obtain many references to the helpful technologies and documentation. This course might have been better only if it were revised for the versions of 2017: if the student ignores the specificity of the versions in the initial installation instructions, the final homework will to be rejected by the automated grader. Shorty put, most recent Rails version is not compatible with Ruby 4.2.x.
