課程概述

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

The materials in this foundational course are in need of updating. They should use ruby and rails versions which are supported by current interations of the mainline linux providors. This course does not reflect will on Johns Hopkins University.

I am afraid this is going to be a rather negative review. Having completed over 10 Coursera courses over the year, and numerous other online classes, this is officially the worst. For me personally, the whole course was a complete waste of time. Put it simply, the presenter can't teach, at least not the MOOCs. There were no structure. The instructions were all over the place, and explanations were inadequate. After drumming how important to actually "code", he proceeded to present the whole lecture showing small pieces of codes.... on slides. After touting how cool and useful Sublime is as a developer tool, he didn't even use it. After telling everyone how useful regular expression is but not part of this course (so he won't explain), he went on to use regular expressions for all the sample codes for the rest of the lecture. As mentioned, there was no structure as to how he present Ruby/Rails as a programming platform. It was bits of code here, bits of code there. Beside getting a feel of what Ruby syntax is like, there was no learning. I am aware there are suggested readings, but then why doing this MOOC at all.

As I check out other courses from the same Ruby specialization, the student numbers are getting smaller. Hardly everyone post on the forums, I also check the Classmates map. I suspect many simply gave up since the Intro classes were so bad. It's really not hard to find better material to learn Ruby/Rails, even just slightly better, even YouTube videos. I am frustrated at myself for putting in the effort (really try) and wasted days. I am leaving this course and unlikely to sign up any MOOC from the same team again.

A lot of things (Ruby version controls, PhantomJS installation) from this course don't work on Mac OS X El Capitan.

The course hasn't been updated in nearly five years. Third week assignment's grader is broken. Rails 6 is out and this course still suggests Rails 4.2.
