def self.permitted_attribute(attr, _options = {})
  # This may seem arbitrary, and improvable by using reflection.
  # Worry not: here we do exactly what Rails does. Regardless of the name
  # of the foreign key, has_many associations use the suffix `_ids`
  # for this.
  #
  # Eg: if the associated table and primary key are `countries.code`,
  # you may expect `country_codes` as attribute here, but it will
  # be `country_ids` instead.
