I am seeing the same problem using the python 2.5 1.0.2.2 windows
install. My code looks like:
@identity.require(identity.not_anonymous())
@expose(template="noquartertg.templates.file")
@expose("json")
@identity.require(identity.not_anonymous())
def file(self, file_id):
return {'file': File.get(file_id)}
@identity.require(identity.not_anonymous())
@expose(template="noquartertg.templates.file_list")
@expose("json")
def file_list(self):
## pull up the current user
user = identity.current.user
return {'user': user,
'files': [f for f in Files.selectBy(owner=user)]}
FILE works fine in both standard web view, and tg_format=json
FILE_LIST works fine in the standard web view, but explodes when I
pass in tg_format=json:
Traceback (most recent call last):

Can anyone help with this? I'd like to avoid having to downgrade/
install components of TG manually, I really enjoy the ease of the
automated 'full stack' windows install. Thanks for the help!
