# frozen_string_literal: true
# We require all the plate and tube purpose files here as Rails eager loading does not play nicely with single table
# inheritance

# This module contains methods associated with the now defunct Pulldown pipleine.
#
# This module was used to generate the purposes and their associations as part of
# both the seeds and the original migration.
#
# Removal of this code shouldn't affect production, but will disrupt seeds,
# and potentially a number of cucumber features. It will probably also require
# the corresponding search objects to be deprecated.
