# Note I did want to put this validator in lib but I could not get it to load
# if put in app/validators. Probably something dumb I was doing, so it could be good
# to move this file later if you can get to the bottom of the issue.
# (I wondered if it was to do with load order - the model loading before the validator -
# although other validators are not exhibiting this issue)

# This is a sub-class of the rails InclusionValidator that will use a different
# validation I18n message with `to` and `from` arguments.
#
# Rather than "is not included in the list", you can use the I18n args to build a
# more helpful more helpful message, e.g.:
# activerecord:
# errors:
# messages:
# numeric_inclusion: "must be between %{from} and %{to}"
