# Use this module to add necessary attributes methods that ActiveModel::AttributeMethods doesn't add
# An ATTRIBUTES constant must be on the model before including this module
# Attributes specified in ATTRIBUTES will be serialized if any ActiveModel::Serializers are used
# Any attributes that shouldn't be serialized can still be set with another attr_accessor, but won't show up in
