Method: ActiveModel::Serializer#serializable_hash

Defined in:
lib/active_model/serializer.rb

#serializable_hash(adapter_options = nil, options = {}, adapter_instance = self.class.serialization_adapter_instance) ⇒ Hash Also known as: to_hash, to_h

associations, similar to how ActiveModel::Serializers::JSON is used in ActiveRecord::Base.

TODO: Include ActiveModel::Serializers::JSON. So that the below is true:

@param options [nil, Hash] The same valid options passed to `serializable_hash`
   (:only, :except, :methods, and :include).

@example
  # The :only and :except options can be used to limit the attributes included, and work
  # similar to the attributes method.
  serializer.as_json(only: [:id, :name])
  serializer.as_json(except: [:id, :created_at, :age])

  # To include the result of some method calls on the model use :methods:
  serializer.as_json(methods: :permalink)

  # To include associations use :include:
  serializer.as_json(include: :posts)
  # Second level and higher order associations work as well:
  serializer.as_json(include: { posts: { include: { comments: { only: :body } }, only: :title } })
