Sobre o curso

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

Some of the coding didn't line up with what was in the lectures, the course had a ton of knowledge and was a great introduction.

Good. But as the course is rather short, knowledge is not covered in detail and may easily be forgotten without extra practice.

It was a really good course, although a bit 'dry' (lessons were similar to each other and thus tiring in longer perspective).

To complete the homework, you must understand every word that teacher told in the video. For this course, I spent 3 weeks.

Good course but incompatible with rails 5. Cryptic errors by automatic graders make submitting assignments a huge hassle.

Great start to rails, provided a practical intro. Could have used a little more frequent practice actually writing code.

The course was handled well. I would have given it 5 stars if the last exercise's test case didn't have a bug.

many of the assignments are outdated and need to be revised using the current version of ruby on rails.
