-# UniquenessOfInMemoryValidator
-#
-# This validtor is designed for especially the following condition
-# - Use `accepts_nested_attributes_for :xxx` in a parent model
-# - Use `validates :xxx, uniqueness: { scope: :xxx_id }` in a child model
-#
-# Inspired by https://stackoverflow.com/a/2883129/2522666
