You should re-use the database connection created in your model file and pass

Thanks, that makes sense. So far, I've only been working on model, test
and widget code, I haven't had to manage the hub connection myself at
all in those contexts.
Is there some magic to model.py's attribute __connection__ that I could
duplicate in util.py? If not, what should the functions do to set their
connection before creating an object with Group(...)? Do I need 'from
turbogears import database' for connection management to work?
util.py:
-------------------------------------------------------------------------
import csv
from myproject.model import hub, Group, User
__connection__ = hub
def load_groups(filename=None):
"""Load groups from CSV format data file:
"group_name","display_name"
"""
data = csv.DictReader(open(filename,'r'))
for row in data:
Group(group_name=row['group_name'],
display_name=row['display_name'])
-----------------------------------------------------------------------
