Active Model Serializers

ActiveModelSerializers, or AMS for short, bring ‘convention over configuration’ to your JSON generation. ActiveModelSerializers work through two components: serializers and adapters. Serializers describe which attributes and relationships should be serialized. Adapters describe how attributes and relationships should be serialized.

Using a serializer

class SomeSerializer < ActiveModel::Serializer
  attribute :title, key: :name
  attributes :body
end
