使用 ActiveModel Serializer 生成嵌套响应时的最佳实践

Question

Is this the only way to generate a response that has nested keys?

module Api
  module V20150315
    class ProductConfigurationSerializer < ActiveModel::Serializer
      cached
      delegate :cache_key, to: :object

      embed :ids, include: true

      attributes :id, :short_code, :rank

      has_many :delivery_product_configurations,
        serializer: Api::V20150315::DeliveryProductConfigurationSerializer

    end
  end
end

The has_many is a serializer which itself calls another serializer. Is the best way to do this right?

Are there alternative ways to do this? Is this the most semantic way?

Answer 1

This is the correct way as indicated in the documentation .

You do not need to specify the serializer for the delivery_product_configurations if it already has a serializer defined. You can refactor thus:

...
attributes :id, :short_code, :rank

has_many :delivery_product_configurations
...
