Module: ArV4Patch

Included in:
ActiveRecord::Associations::Preloader
Defined in:
lib/kashmir/patches/active_record.rb

Overview

We have to reopen Preloader to allow for it to accept any random attribute name as a preloadable association.

This allows us to send any arbitrary Hash to Preloader, without requiring it to be an ActiveRecord relation in advance.
