About the course
Our Advanced Ruby training course will take delegates on a journey into more advanced usage and Best Practices of coding in Ruby. The course is rich in hands-on practical exercises to bring the techniques and theory alive.
Ruby is an Open-Source language and forms the backbone of a number of web app frameworks, most notably Rails (check out our Ruby on Rails training course for more details).
Online and in-house face-to-face options are available - as part of a wider customised training programme, or as a standalone workshop, on-site at your offices or at one of many flexible meeting spaces in the UK and around the World.
-
- Reflection and Ruby's object model
- Methods and Instance variables
- Using Pry and Debugging Ruby Code
- Ruby Metaprogramming
- Calling methods
- ...and much more!
-
Ruby developers who want to get right under the bonnet with the Ruby language.
-
Previous experience of Ruby development is required (for instance if you've attended a Ruby Programming training course), and a good grasp of OO programming principles.
-
This advanced Ruby course is available for private / custom delivery for your team - as an in-house face-to-face workshop at your location of choice, or as online instructor-led training via MS Teams (or your own preferred platform).

Ruby Programming Training Course
Ruby Reflection:
Discussion: Ruby's object model
How to: list the methods available to an object
How to: see the values of an object's instance variables
How to: show an object's class hierarchy
How to: use pry to learn more about our code (including debugging)
Ruby Metaprogramming:
How to: call methods dynamically with `send`
example: serialising and deserialising an object to and from a hash
How to: define methods dynamically with `define_method`
example: implementing ActiveRecord's `find_by_xxx` methods
How to: catch calls to undefined methods with `method_missing`
example: implementing (in another way) ActiveRecord's `find_by_xxx` methods
How to: define classes dynamically with `Class.new`
example: reimplementing the standard library's `Struct` class
Bringing it all together
exercise: building simple library to interact with RESTful web service by generating code from an XML definition of the service
Discussion: when to use metaprogramming
