Overview

Event Record Hooks

These hooks are called during the life cycle of Sequent::Core::EventRecord. It is recommended to create a subclass of Sequent::Core::EventRecordHooks when implementing this in your application.

Sequent.configure do |config|
  config.event_record_hooks_class = MyApp::EventRecordHooks
end

module MyApp
  class EventRecordHooks < Sequent::EventRecordHooks

    # Adds additional metadata to the +event_records+ table.
    def self.after_serialization(event_record, event)
      event_record.metadata = event.metadata if event.respond_to?(:metadata)
    end

  end
end
