Instance Method Details

#adapter ⇒ Object

Each ‘RepresentationWithoutId` instance needs to be handled by a separate adapter. We can’t safely combine representations into a single datastore query, so we want each to handled by a separate adapter instance. So, we use the representation itself as the adapter.
