PolymorphicRelationshipField.AfterReadHooks

Related types

• PolymorphicRelationshipField

  PolymorphicRelationshipField configures a link to one document from any of the target collections.

• OutputTransform

  OutputTransform changes one field in the response without changing storage. Register it with the field's AfterRead method; it is not a Hooks list. T is the field's response type, which differs from its stored type for references. Its context supplies response values, which may include related documents and locale fallback. Return Keep, Set, or Clear, as for a write transform. Field read access still runs afterward; visible context data is not permission to expose it. AfterRead runs after resource response hooks on reads and mutation responses, before final field redaction. Registration determines the callback phase. An error stops the response and can roll back an uncommitted mutation.

• Value

  An immutable scalar, object, list, or populated document value.
