hi,
is there anyone knows how to produce db output select into xml please?
my intention is to convert my audio mp3 table into xml and then put it
on web2py apps.
e.g. (source from : http://www.voice2page.com/info/v2ppage_codes.html)
http://voice2page.com/info/

Not sure I understand.
Is your problem that you do
python nweb2py.py -a 'password'
and you get?
TypeError: cannot create weak reference to 'classobj' object
I have never seen this before. How do you run it? Which python
version? Do you have a loger traceback?

Is it that Ubuntu 11.04 beta, and some package may be unstable???
what's your bpython version?

mine is 0.9.6.2
In response to the events in which bpython isn't installed/crashed, my

If you are compiling mercurial from source you need that.
Install that first and try again.

It should not be.
After caching, it must not hit database, until cache expires.
So, after the cache is set and you insert something, then it'll take time
until cache expires, to have another db hit.
Unless db is queried again, new data will not be there.
It's as simple as that.
As others said,

I think what you have works for this. I wanted to be able to throw a

every time a build is run. sometimes

Redirecting should work. Can you get it to work with just one form? Once you
get one form working, then try adding the second form. Start simply.
It looks to me like it might be stuck at the very beginning with "import
os". In MacOS terminal, can you do a simple "import os" in Python shell?
$ python

yup, no problem doing import os

You probably need 'answers' to reference auth_user or come up with a scheme
to track the person answering.
Then, select() a question and build a form. Perhaps:

form = SQLFORM(db.answers)

Hi,
no the values should not be empty. In the given example, you can
choose available items from the drop-down-boxes and they can just be
there, if there is content behind these keys.
The problem must be somewhere else.

You need to pass the URL('default','download') to SQLFORM(..) as in
SQLFORM(...,upload=URL('default','download'))
and the widget should have it automatically.

I do not feel the necessity.
What I do is simply version control the files (specifically models).
Any change (whether in the future or reverting to a past version)
result in an automatic migration.
