Module: BentoSearch::Results::Serialization

Extended by:
ActiveSupport::Concern
Included in:
Author, Link, BentoSearch::ResultItem
Defined in:
app/models/bento_search/results/serialization.rb

Overview

Call #dump_to_json on a BentoSearch value object (such as BentoSearch::Result or ::Author) to get it in Json

Values marked with serializable_attr in BentoSearch::Result are included in seralization.

At present metadata and configuration are NOT serialized: #decorator, #display_configuration, and #engine_id are not included in the serialization, so when loaded from serialization, ResultItems will not have such things set.

  • Works by getting and setting instance variables directly, ignores getters/setters

  • This means decorated values are NOT included in serialization, the raw values are what is serialized. This is intended, we serialize internal state, not decoration which can be recreated. You should make sure the decorators you want are applied after de-serialization.

  • preserves html_safety status in serialization, by adding extra ‘_attr_htmlsafe: true` key/value
