Feature #2375
Updated by Brett Smith about 10 years ago
* Log object is added even if "update" does not actually change the database content (e.g., "node is still alive") * Log object's "properties" attribute _(rename it, it's currently called "info")_ includes: ** timestamp of the change ** uuid of user making the change (usually same as modified_by, except delete and some updates) ** class name and uuid of the affected object (although these are also in log.object_kind and _uuid) ** update type (create, update, delete) ** etag of the new version (nil for delete) ** etag of the old version (nil for create) ** all attributes of the new version (nil if deleting) ** all attributes of the old version (nil if creating) * modified_by is current_user (the user whose transaction is being logged) * owner_uuid is system_user (this prevents users from deleting logs)
