Question

我想做同样的伎俩 - https://robots.thoughtbot.com/fast-json-apis-in-rails-with-key-based-caches-and，但是在AMS 0.10.0.rc中无法做到，因为AMS现在没有#serializable_hash方法。

你建议做什么？

Answer 1

Updated to the new version of active_model_serializers :

class BusinessDistanceSerializer < ActiveModel::Serializer
  attributes :distance

  def attributes options = {}, reload = false
    data = super
    data.reverse_merge! ActiveModel::Serializer.adapter.new(BusinessSerializer.new(object)).serializable_hash
    data
  end

end

Notice the reload = false argument.

Answer 2

我正是这样做的。

class BusinessDistanceSerializer < ActiveModel::Serializer
  attributes :distance

  def attributes options = {}
    data = super
    data.reverse_merge! ActiveModel::Serializer.adapter.new(BusinessSerializer.new(object)).serializable_hash
    data
  end

end

将两个Active Model Serializers v 0.10组合在一起
