This course continues the Introduction with the same test-driven approach and delicious intensity of the material. Efforts to finish the course will be greatly rewarded.

I really liked writing the authentication myself. I've relied on Devise (and will continue using it mostly) but really got an appreciation for what was going on.

A detailed, thorough journey through Rails' model, view, controller framework. I took this after the popular Rails tutorial, which served as a great intro. I learned a huge amount about the main components of Rails - Active Record, Action Controller and Action View. There are no boring code-along videos, just concise lectures with slides and assignments.

This course is not really for beginners. It's challenging, just because of the many potential technical issues you can run into with Ruby, Rails, databases, servers and tests. I recommend having at least six months of programming studies behind you before diving into this course.

The previous course in the series is also a must - even if you think you already know the basics, you'll have important stuff reinforced.

This is a great course. I had no knowledge in Ruby and web development before this course (I skipped Intro to Rails course which is the first in this specialization). This course has very well designed coding assignment with tests written in RSpec. All four coding assignments all build upon the previous one, so there is no context switch, and they together build up Todo List App. I love the fact this course is very focused on MVC of Rails. I would recommend it to anyone who would love to learn Rails and MVC pattern.

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.

This course is a pretty detailed analysis of Controller and View roles in MVC with all it's syntax and conventions but it's definitely require some additional material for students to find by themselves. Anyway quizes and assignments are amazing - very good practice even for a little bit more advanced students than complete beginners!

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.

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.

After this course you'll be able to develop a functional web app using Rails' build-in database. Now you can produce your own data using all the options Rails has to offer; that's nice because you don't depend on external API's to get the back-end stuffs. Recommended!

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 third part of this specializations.

Just like the Course about the introduction to ruby this course has helped me to understand more Rails and the active record i really want to say : Thanks! to the professor who give me the opportunity to take this course :D From venezuela! Gracias mi pana :)

2 things are cerating if you take this course, - you will hate it when you take it. - you will LOVE it when it's over. You will really like where it takes you when it gets over and make you feel really good on how much your skills have improved.

Wonderful course. Thorough instructions with a great level of detail. Great assignments that reinforce the lessons. Would recommend to anyone wanting to learn about Ruby on Rails specifically or Web Development generally.

I learned so many knowledge from this course, not just the Rails , I also have comprehend the ruby , the ruby-gems and the HTTP/REST protocol. and the assignments are not particularly difficult for the beginners like me.

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.

This course is awesome, while the delivery is quite slow, I found it watching it at 1.5x speed and following all the graded assignment help me to ace Rails at my new job which uses Rails as primary Web Dev Framework.

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.

I have worked with rails for sometime then stopped for a while and after that I took this course as a refreshment, and t really worth the time, actually I learned some new stuff that I did not came across before

Thank you for your course. I am a penetration tester. I can get a better understanding for your course. After finishing it, I can give more security suggestion about code review and security architecture.

A nice continuation to course 1 of this specialization, deeper dive into RoR, among other things you will learn how to manipulate/display database data and how to authenticate/authorize users!

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.

This course teach me a lot of complex things like authentication, nested resources and authorization. This is a great course for someone that want to learn Rails

Awesome course, i have learned a lot about active records, rails database management, action pack, and so on. it's a very completed course.!

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 course assignments is hard and takes lots of hours but are valuable to me as it systematically consolidates rails' components for me.
