Unfortunately, it really needs to use the hub that's in use by the
model classes... from a random model.py:
__connection__ = AutoConnectHub()
# (or PackageHub)
class Foo(SQLObject):
...
In a multi-application world, it'll be possible to have different
parts of a site going to different databases. that won't be the common
case, though.
Sticking to the common case, we just need a nice way to get ahold of
the hub in question. There are probably a small handful of ways we
could find the model module and get the hub from it. Unfortunately,
I'm out of time for exploring that now, and I'll be offline for a
while. I hope I'll be able to get back online at least briefly later
today...
