19956	Manual PrimaryKey isn't updated after save, create	grzesiof@…	nobody	"The regular auto id field is updated after the object is saved to the database. This doesn't happen when using manual primary keys:

{{{#!python
class A(models.Model): pass
class B(models.Model):
    id = models.IntegerField(primary_key=True)

A.objects.create().pk # 1
B.objects.create().pk # None
}}}

The pk value is only updated for auto fields:
