Per bundle computed serial number for entities.
The difference with the Serial module is that the field value is not stored but computed.
The sequence is preserved if entities from the bundle are being deleted.
When a sequence within a bundle is needed (e.g. invoice number, ...).
Add the field to an entity type bundle (e.g. Article content type). Set the serial id to start from and the node id that will be used as the first entity to count from.
- Optionally initialize values for existing entities
- Lightweight system wide configuration without per bundle field definition by implementing hook_entity_bundle_field_info() [WIP]
