Defined in:

Overview

Synchronizes EmbeddedAsset records with the actual content of a parent record.

When content is saved, this service:

  1. Parses the HTML content to find all data-embedded-asset-uuid attributes
  2. Deletes any EmbeddedAsset records that are no longer in the content
  3. Returns statistics about what was synced

Usage:
result = EmbeddedAssets::SyncService.new(article).call
result # => { found: 5, orphaned: 2, deleted: 2 }

The service is idempotent and safe to call multiple times.
