# Rails datetime_select and similar use multiparameter attributes which are
# these dawful things from the bowels of activerecord and actionpack. This
# module extends virtus models to coerce multiparameter attributes back together
# before assigning attributes.
#
# Here's the implementation for ActiveRecord:
#
#   https://github.com/rails/rails/blob/11fd052aa815ae0255ea5b2463e88138fb3fec61/activerecord/lib/active_record/attribute_assignment.rb#L113-L218
