2003	ManyToManyField(SomeModel, blank=True, null=True)  does not work	anonymous	Adrian Holovaty	"I have a ManyToManyField that I want to be able to leave blank but if I do that I get this error:

""instance needs to have a primary key value before a many-to-many relationship can be used""

I only get that error in the AdminCP though. "	defect	closed	contrib.admin		normal	invalid			Unreviewed	0	0	0	0	0	0
