I found out that this is caused by an unclean import generated by the
quickstart model.py:
from sqlalchemy import *
from turbogears.database import metadata, session
from elixir import *
Here, "metadata" from the exlixir import shadows "metadata" from the
import above. This "metadata" object is not connected to a database.
As a quick fix, which I implemented in r3378 and r3375, you can move the
Elixir import up one line:
from sqlalchemy import *
from elixir import *
from turbogears.database import metadata, session
This is a bit unclean, since the "metadata" object from
turbogears.database is in turn imported from activemapper, which will go
away at some point. turbogears/database.py should provide the correct
metadata object, depending on which sqlalchemy extension is used.
