[SQLObject] createTable returns NoneType error

[Martin d'A. <Mar...@s2...>]

Hi,

I have this code where I want to pre-define classes for the tables, and 
connect them at run time to the database, but it does not work. Here is 
the code:

#!/usr/bin/env python

from sqlobject import *

class Person(SQLObject):
   # Connection always defined at runtime
   name = StringCol(length=255,default=None)

def main(db_name):
   conn = connectionForURI('mysql://user:passwd@server/'+db_name)
   trans = conn.transaction
   Person.createTable(trans)

if __name__ == '__main__':
   main('test')

% ./simple.py 
Traceback (most recent call last):
  File "./simple.py", line 15, in ?
    main('yo')
  File "./simple.py", line 12, in main
    Person.createTable(trans)
  File "/usr/local/lib/python2.3/site-packages/sqlobject/main.py", 
line 973, in createTable
    if ifNotExists and cls._connection.tableExists(cls._table):
AttributeError: 'NoneType' object has no attribute 'tableExists'


I am sure I am making a mistake... can someone help please?

Thanks,
Martin
