Aquí tienes otro ejemplo, con un escenario de entrada ligeramente diferente, pero que sigue aprovechando los mismos mecanismos y ganchos:

https://github.com/paviliondev/discourse-topic-previews/blob/master/assets/javascripts/discourse/connectors/edit-topic/select-thumbnail-connector.hbs

github.com/merefield/discourse-topic-previews-sidecar

plugin.rb

            "topic_list_default_thumbnail",
            "topic_list_thumbnail_width",
            "topic_list_thumbnail_height",
            "topic_list_featured_images"
          ].each do |key|
            Site.preloaded_category_custom_fields << key if Site.respond_to? :preloaded_category_custom_fields
            add_to_serializer(:basic_category, key.to_sym, false) { object.custom_fields[key] }
          end
          
          TopicList.preloaded_custom_fields << "user_chosen_thumbnail_url" if TopicList.respond_to? :preloaded_custom_fields
          PostRevisor.track_topic_field("user_chosen_thumbnail_url".to_sym) do |tc, tf|
            tc.record_change("user_chosen_thumbnail_url", tc.topic.custom_fields["user_thumbnail_choice"], tf)
            tc.topic.custom_fields["user_chosen_thumbnail_url"] = tf
          end
          PostRevisor.track_topic_field("image_upload_id".to_sym) do |tc, tf|
            tc.record_change("image_upload_id", tc.topic.image_upload_id, tf)
            tc.topic.image_upload_id = tf
          end
          
          Discourse::Application.routes.append do
            mount ::TopicPreviews::Engine, at: '/topic-previews'
