Hi,
I saw that SqlAlchemy is supposedly compatible with DBMechanic which
is some kind of replacement for Catwalk. However, when following the
DBMechanic website's instructions, I end up with an error. I do the
following in my controller.py file:
from model import metadata
from dbsprockets.dbmechanic.frameworks.tg import DBMechanic
from dbsprockets.saprovider import SAProvider
class Root(controllers.RootController):
dbmechanic = DBMechanic(SAProvider(metadata), '/dbmechanic')
<rest of code cut for brevity ... >
This gives me a huge traceback:
Page handler: <bound method DBMechanic.index of
<dbsprockets.dbmechanic.frameworks.tg.dbmechanic.DBMechanic object at
0x0178E410>>
Traceback (most recent call last):

I am following the instructions found here:
http://code.google.com/p/dbsprockets/
Also, I am currently trying to work my way through the Spree tutorial
found here: http://www.splee.co.uk/2006/10/14/simpleblog-part-1/
Unfortunately, its code for creating a blog post via the tg-admin
shell does not work which is why I was trying the dbMechanic. Any
advice is welcome.
