def serialize(options = {})
  hash = super()

  if options[:root] == true
    hash = { @record.class.model_name.element.to_sym => hash }
  elsif options[:root]
    hash = { options[:root].to_sym => hash }
  end
  opts = remove_serializer_class_options(options)
  opts.delete(:root)

  hash.to_json(opts)
end

#serialize_in(json_string, options = {}) ⇒ Object

Takes a record’s attributes represented as a JSON string, and returns a hash suitable for direct assignment to the record’s collection of attributes. For example:

s = ActiveRecord::AttributeMap::JsonSerializer.new(record, :api)
record.attributes = s.serialize_in(json_string)
