Well, you're right, it's tough to give advice, especially when I've not
seen that particular error.
The basics, though, would helpo: Which versions of your packages are
installed? Assuming you're using a virtualenv, just get us a listing of
that virtualenv's site-packages folder.
Did you build the virtualenv with --no-site-packages ?
This segment in particular looks suspicious:
Module pps.controllers.secure:1217 in mp_add_order
<< if status != 'OK':
if len(multipack.orders) < 1 :
DBSession.delete(multipack)
multipack = None
return dict(status=status,mp_id=mp_id)
>> DBSession.delete(multipack)
What I'm seeing here is something that looks like "I added an object, but
now need to delete that object, before I've actually committed it to the
database". Is that correct? If so, you might be better off creating the
object, working with it, and then only adding it to the database at the end
of the controller method, resulting in your getting rid of a delete() call.
