Module: Mongoid::Traversable::DiscriminatorRetrieval Private

Defined in:
lib/mongoid/traversable.rb

Overview

This module is part of a private API. You should avoid using this module if possible, as it may be removed or be changed in the future.

Module used for prepending the discriminator_value method.

A separate module was needed because the subclasses of this class need to be manually prepended with the discriminator_value and can’t rely on being a class_attribute because the .discriminator_value method is overridden by every subclass in the inherited method.
