I think there is some confusion here. I'm guessing you are using mysql-
python v1.2.1 since a 1.x mysql version would probably date back to
the mid to late 90s. Ask the admin if it is possible to upgrade mysql-
python for which you do not need to upgrade MySQL itself or even take
down the database.
I have a model like such:
class Response(models.Model):
raw_text = models.TextField()
respondent = models.ForeignKey('auth.User')
Response has a related model attached to it:
class Code(models.Model):
response = models.ForeignKey(Response)

We're using ASI & Django and seeing the same thing.

I read the docs you pointed med to and now I have few more questions:
1. Is it possible to use two or more different back-ends with a single
Django project? For me it seems not.
2. After rethinking my needs I realized I need simple functions as e.g.

Interesting solution - after all that maybe it's more concise to just
use the 'extra' filter instead since you're making it specific to
