[SQLObject] Aggregate columns / change connection

[Achim D. \(ProCoders\) <do...@pr...>]

Hi,

I've seen Brad Bollenbach very good talk at Europython, and now I finaly
found the time to give SQLObject a try. I really like it, but have some
questions:

- In the examples, the connection is always hardcoded in the module, where
my classes are definied. In real world apps I would like to specifiy the
connection from outside of the module. I might have two different instances
of my app, using two different servers/databases. How would I do that?

- What's about aggregate columns? I want to build a system with some kind of
ranking mechanism, where I usually only want to show the average ranking. As
far as I understand, I would have to calculate that value 'by hand', if I
use SQLObject. Is that right?

regards,
Achim
