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 …

    This course is peach. Amazingly coached by Prof. Hazins. I learnt a great deal about web development, ruby language, the Rails framework, version controlling using GIt, using cloud based deployment service heroku and in general it increased my knowledge about the internet on the whole 😉

    I think this was a great course. The various issues with versions of ruby, rails, gems, operating systems, etc was frustrating at times but at the same time very much “real world” as I learned how to reflect about possible solutions and use online resources to sleuth the problems. Looking forward to the next courses and becoming more comfortable with rails.

    The content is great so far, learned a lot from this course. However, the version is too old and I need to downgrade a bunch of staff to make assignment work. It should be better to update the assignment at lease to rails 5.x. Also, it should be better to cover some content about either MySQL or PostgresQL since SQLite is serverless and it is different to most of man SQL language with server.

    It is pretty cool! Although the video might seem old, but most of it still works. Additionally, mostly you can find the answer from the forum. Also, you can try to figure it out by trying different things. I would say the bundle install (bundle update) is usually the most annoying one because they just depend each other, and sometimes it will be hard to figure out what is happening!

    I went through this material after first completing the Ruby on Rails tutorial by Michael Hartl. So far, this series is greatly explaining the core details of Rails. This course also explained some of the basics of Ruby which I hadn’t memorized. There are some technical issues for Windows users and the discussion forums are nearly empty, but it’s still a pretty good free resource to learn Rails.

    The course is out of date. Assignment code is out of date. You have to install outdated gem versions and due to which run into various issues. Also the rspec test is buggy. I had to make changes in rspec test in the boilerplate to make it work.

    You know, the course is really good in knowledge. But there are such a lot of blanks you have to figure out when you make you assignment. Well, I had some experience in programming, and only that helped me to pass this course. Too much missed and not explained information. So if you’re a beginner and chose Ruby as a first step this course won’t help you. Also, I understand that the course was done long time ago, and it’s not possible to update videos. I had such a lot of problems with bundles and versions, especially when it comes to assignments. I would like to thank teachers for the support in forums, I got a lot of solutions to my problems in your answer. Not all of them though( Sometimes it was like working with blind eyes.

    About me: I Have some experience with Python, Java, C++. Complete beginner with anything webdev. The lectures (5 stars): The lectures are light, the explanation is clear and concise. Some details are left out but it is probably for the best (…and can be filled in with a little “googling” ). Great for a beginner. The SW Installation and coursework (1 star): A good part of the SW instructions seem grossly out dated. For the final course assignment: 1 I ended up ditching “http://railsinstaller.org/en” and installed an up to date version of each component individually. Also, I ditched “phantomJS” & used “http://chromedriver.chromium.org/” instead. Took me +10 hours….

    Do NOT pay money for this course! The grader and examples are so out of date and the ruby / rails ecosystem is so broken you’ll spend most of your time trying to resolve bundler conflicts. I was absolutely unable to get a working environment for the end of this course. Spend your money and time else where.

    The course has really helped me to learn ruby on rails which is a complex application development technique in a very simple manner. All the modules and assignments in the course are developed keeping the end user in mind and to enhance his/her development skills and understanding of this course. I would highly recommend this course to anyone who would want to learn ruby on rails and develop his.her development skills in this platform

    It is a really nice course, the instructor explains the subjects very well, the only problem is the API used on the exercises is not available anymore and the last exercise requires rails 4 and it’s kind of difficult to find out why the exercise is not approved even though the tests are passing locally.

    Spent more time sorting out gem dependencies than doing the actual work and the external API service to pass the assignment is no longer working so that also restricted my ability to learn. Course content and lectures are really great though and very easy to follow.

    Ruby is a magical language. Literally. So much in Ruby appears to happen by magic that it is actually very disconcerting to a more traditional programmers (like me) who can trace every call back to its source. With Ruby (or more precisely with Rails) you have to let go and have faith that the magic will somehow achieve your objectives. This course does a great job of introducing you to how the magic works, and starts unveiling what’s behind the curtain. A great introduction to the language!

    Amazing Course made by Professor Kalman Hazins. Lot of dedication by him. The code used are up to date. And one will always find him on discussion forum for answering doubts which was a great thing. This course will give you good amount knowledge and hands on pratice on Git, Ruby programming language, Rails framework and also you get to deploy a website on Heroku. You will also create website which uses only API for data and another app in which you will database for data. Best place for beginners to start their career in Web Development.
