Great explanation of not so easy to understand concepts. Lecturer provides good example that can help material better and see how what you've learned can be applied to real world scenarios.

Awesome course that took us to database learning and how they interact with rails application. A lot of stuff learned.

This course is awesome, even to who know a little about Ruby on Rails. There are much tips to help you develop a good application.

Thank you Prof. Kalman Hazins. I like your course very much. It is useful and filled with a lot of information. Thank you for your hard work. I'm really appreciated it. Hope you have more courses on Coursera.

Thorough, excellent coverage of the the subject. Well worth your time.

Thank you so much, i learnt a lot in this course

Great course for intermediate level!

A little challenging for Ruby beginners but extremely rewarding

Great program. Well structured, with lots of additional resources that make for easier self-study. Videos are just the right length to provide the knowledge without being too long and too filled with details. All in all, this is an excellent 2nd course in my Ruby on Rails Web Development skills development.

I loved the course.

Excellent course, good combination of broad strokes and practical, specific tips.

Very good course!

Very intensive, a lot of work on assignments but at the end very happy to done this...

AWSOME! Easy to follow, intuitive, and helpful!

Amazing course, i had complete Ruby on Rails tutorial by Michael Hartl and i was still doubtful about alot of things but i think this course has put me on the right path and now im really confident and i think i will go all the way, Johns Hopkins university courses are amazing, very good for learning. I highly recommend it to anyone wants to learn Ruby on Rails.

I'm very happy with the course, that was awesome to learn a lot and increase my knowledge with Ruby on Rails

Wonderful job of explaining rails development! Awesome!

Good

What is an application without a place to store and retrieve data. I have a moderate amount of experience with SQL from working with SQL Server and Oracle DB, so picking up this material was a natural extension of that experience to leverage a database for a full-featured application.

Nice course. A good overview upon: routing, helper, controller, nested resources

Very good and resumed analysis of ActiveRecord and ActionPack

Very good course for basic web frame work .

In this course I got new skills about the Ruby on Rails framework using the incredible Active Record ORM and the Action Pack. Great videos!

The first two courses in this series have really rekindled my interest in software development after many years away from it. Kalman does a great job - the lectures are interesting and the assignments are challenging.

Well taught and very interactive. I recommend this to every one interested in understanding the core concepts of rails
