Given:
{{{
class AbstractGlue2Model(models.Model):
ID = models.CharField(primary_key=True, max_length=200)
<stuff>
class Meta:
abstract = True
db_name = 'glue2'
...
class Contact(AbstractGlue2Model):
Detail = models.CharField(max_length=128)
Type = models.CharField(max_length=16)
}}}
A migrate that should create the new Contacts DB objects sees inherited
fields (such as ID), but is missing Meta db_name value:
{{{
(Pdb) pp hints['model']
<class 'Contact'>
(Pdb) pp hints['model']._meta.db_name
*** AttributeError: AttributeError("'Options' object has no attribute
'db_name'",)
(Pdb) pp hints['model']._meta.abstract
False
(Pdb) pp hints['model'].ID
<django.db.models.query_utils.DeferredAttribute object at 0x10f97d6d0>
}}}
