New description:
I have a bunch of Models of the form
{{{
#!div style="font-size: 80%"
{{{#!python
class AbstractOwnershipModel(models.Model):
owner_user= models.ForeignKey('auth.User')
class Meta:
abstract = True
class AnOwnedModel(AbstractOwnershipModel):
#...
}}}
}}}
Which I tried to change to
{{{
#!div style="font-size: 80%"
{{{#!python
class AbstractOwnershipModel(models.Model):
owner_user= models.ForeignKey('auth.User',db_index=True)
class Meta:
abstract = True
}}}
}}}
But makemigrations reports that there are no changes even though I would
expect a bunch of indexes to be created.
