# frozen_string_literal: true
# Overrides `#serializable_hash` to raise an exception when called without the `only` option
# in order to prevent accidentally exposing attributes.
#
# An `unsafe: true` option can also be passed in to bypass this check.
#
# `#serializable_hash` is used by ActiveModel serializers like `ActiveModel::Serializers::JSON`
# which overrides `#as_json` and `#to_json`.
