You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: fieldset.rb
    path of file: ./repos/workarea/core/app/models/workarea/content
    
    the code of the file until where you have to start completion: module Workarea
  class Content
    class Fieldset
      include AssetLookup

      attr_reader :fields
      attr_accessor :field_suffix, :name


    
      def field(name, type, options = {})
        name = [name, field_suffix].join if field_suffix.present?

        klass = if type.is_a?(Class)
                  type
                else
                  "Workarea::Content::Fields::#{type.to_s.camelize}".constantize
                end
