The Ruby on Rails framework has hit 4.0! The new version brings exciting features, revises some of the old conventions, and removes lesser used components.
Staying on Rails 3.2 or, gasp, 2.3 is not an option. But there's more to upgrading than just changing your Gemfile.
What You’ll Learn
In this course, we'll upgrade a Rails 3 app to Rails 4 and along the way work through:
- Strong Parameters and Security Considerations
- TurboLinks, what it is, how it works, and how to debug/disable them
- Strategies for dealing with removed features you rely on
- Tactics for upgrading as painlessly as possible
What’s In a Class?
This is not “sit back and watch slides” — all Jumpstart Lab courses are hands-on. We work with real applications and you’ll implement these tools and techniques yourself. By the end of the class you’ll have real experience, real skills, and real code to reference.
Who’s this for?
Course attendees should be comfortable with Rails 3, but absolute mastery is not required.
What equipment is needed?
For this session you'll need:
- a computer with Mac, Linux or Windows
- Ruby 2.0 and Rails 3.2 and 4.0 installed
- The join.me local client installed
- a stable internet connection for video streaming
- external headphones and microphone
- a webcam
Detailed setup instructions will be sent out a week before the class takes place.
