13666	Updates with F objects on decimal fields raise MySQL warnings	KyleMac	nobody	"Doing something like the following:

{{{
MyModel.objects.filter(whatever).update(price=F('price') - Decimal('1.00'))
}}}

raises an exception due to an ignorable warning from MySQL.

This is basically identical to #12293 except that the documentation would have you believe that this should work without any extra work."	Bug	closed	Database layer (models, ORM)	1.7	Normal	worksforme		josh@…	Accepted	0	0	0	0	0	0
