5309	[Patch] Marking instances as db-stored via is_stored	David Cramer <dcramer@…>	nobody	"This patch adds a flag to instance called 'is_stored'. By default it is set to None. When a DB instance is available in the database it is True, and when its removed it is False.

This corrects the need for Django guessing based on the PK value if it needs to try to do an update or insert, and should throw exceptions if you try to do an insert (.create) when a matching pk exists."		closed	Database layer (models, ORM)	dev		fixed	is_stored feature		Design decision needed	1	1	1	1	0	0
