Overview

A collection of rails-specific decorators. Why? Because Rails is magic, and it is like stepping on a minefield. Rails objects can trigger side-effects (like calling database queries, or even API queries). And from the end-user perspective, Rails’ internal variables are useless. They care more about database attributes, which requires some extra steps to display if I don’t want to use ‘#inspect`.
