Ruby Science: Inheritance, Composition, STI, and Polymorphic Associations
Todays' release of Ruby Science includes two new chapters. If you're already reading Ruby Science, make sure to log into GitHub and download the latest version.
In this week's updates, we cover composition and inheritance. You'll learn about the uses and drawbacks of Single Table Inheritance (STI), as well as how to convert an STI hierarchy to use composition through polymorphic associations.
