#cache_key(obj, options) ⇒ Object

This isn’t working, comment out this optimization def create_representation_with(doc, options, format)

cache.fetch(cache_key(represented, options), cache_options) do

  response = HalApi::Representer::Caches::SerializedJson.new(JSON.dump(response)) if (options[:to_] == :json)
  response
