Update:
If I run:
results = meta.Session.execute(s).fetchall()
and pass that to paginate, it works.
I guess I just needed the ResultProxy, and not a collection of mapped
objects.
Mike, if you have any additional insight for me, I would appreciate
it.

The bad news with results = meta.Session.execute(s).fetchall() is
that it runs for every page in the paginator, fetching all rows each
time.
Thoughts, anyone?

oh. if the paginator uses slices to provide LIMIT/OFFSET, you need to
construct a Query that can be limited via slice. don't use select() here,
use Query fully.

Here you go:

File '/home/aw/venv/dev/lib/python2.6/site-packages/WebError-0.10.1-
py2.6.egg/weberror/evalexception.py', line 431 in respond

you can't call count() when you've used from_statement, that should be
raising an error. the bug is that no error is being raised.

Ok, I see.
So what's the best way for me to construct and execute this query?

use Query:
session.query(MyClass.someid,
MyClass.somethingelse).filter(..whatever..).order_by(..whatever...)

Well, that worked great:
q = meta.Session.query(m.Hit.referer, func.count(m.Hit.id))\
.group_by(m.Hit.referer)\
.order_by(func.count(m.Hit.id).desc())
Thanks!
ps: Is there a better way to specify the count in the order_by?
