3997	Missing default value causes exception on save	Henrik Vendelbo <info@…>	Philippe Raoult	"Using MySQL I have noticed a common cause for save to fail. Especially BooleanField's with no default value. If there is no default value, MySQL will return a Warning for data truncation, which will cause the save to fail. I believe that I tried to catch MySQLdb.Warning and pass on it with no improvement.

1) A warning should not cause the transaction to fail
2) If a default value is effectively required, validate should check for it"	Bug	closed	Database layer (models, ORM)	dev	Normal	fixed	doc		Accepted	1	0	0	1	0	0
