Class: Hyrax::Actors::AttachMembersActor

Inherits:
AbstractActor show all
Defined in:
app/actors/hyrax/actors/attach_members_actor.rb

Overview

Attach or remove child works to/from this work. This decodes parameters that follow the rails nested parameters conventions: e.g.

'work_members_attributes' => {
  '0' => { 'id' => '12312412'},
  '1' => { 'id' => '99981228', '_destroy' => 'true' }
}

The goal of this actor is to mutate the #ordered_members with as few writes as possible, because changing #ordered_members is slow. This class only writes changes, not the full ordered list.

The env for this actor may contain a Valkyrie::Resource or an ActiveFedora::Base model, as required by the caller.
