Entities sync service

Replicate providers, topics, tags from manifest using external IDs

ContentProviderSync:

  class ContentProviderSync
    def sync(provider_data)
      ContentProvider.find_or_initialize_by(external_id: provider_data["id"]).tap do |p|
        p.update!(name: provider_data["name"])
      end
    end
  end

TopicSync:

  class TopicSync
    def sync(topic_data, content_provider)
      Topic.find_or_initialize_by(external_id: topic_data["id"]).tap do |t|
        t.update!(
          content_provider: content_provider,
          title: topic_data["name"],
          # map other fields...
        )
        sync_tags(t, topic_data["tag_ids"])
      end
    end
  end

TagSync:

  class TagSync
    def sync(tag_data)
      Tag.find_or_initialize_by(external_id: tag_data["id"]).tap do |t|
        t.update!(name: tag_data["name"])
      end
    end
  end

Start by locating the ContentProviderSync, TopicSync, and TagSync entry points and the manifest data they consume. Trace the existing ContentProvider, Topic, and Tag models to identify the fields and tag relationships that must be synchronized by external ID. Done means providers, topics, and tags can be replicated from the manifest without creating duplicates, including topic tags.
