I managed in this way:
>>> subquery = Father.objects.filter(sons__in=[adam, bernard])

Is there a better way to do so? (maybe more efficient?)

Hi,

I had to clean my application database from old models without losing
data.
So, I copied my tables to another db, dropped them, run syncdb and
copied data back.
