10967	save(force_update=True) crashes with model inheritance	Lorenzo Gil Sanchez	nobody	"When there is a subclass with no fields and you try to save it with obj.save(force_update=True) it will crash with this exception:

{{{
AttributeError: 'NoneType' object has no attribute 'rowcount'
}}}

The problem is that an or condition should be an and instead. I'm talking about the check in Model.save_base that test if there are non primary fields to save. This is better explained by the patch itself."	Bug	closed	Database layer (models, ORM)	1.0	Normal	duplicate			Accepted	1	0	0	1	0	0
