#serializable_hash(options = nil) ⇒ Object

Override of serializable_hash:

In the case of the category and author of a product, since we can’t query the OMS API for a single entity directly, we’ll replace the entity id field (category_id, author_id) with the serializable hash of the actual object (category, author) as part of the serializable hash:
