Hi,
when copying and pasting the example from the announcement into files,
it wont run due to some errors:
2009/2/5 Massimo Di Pierro <mdipie...@cs.depaul.edu>:

Here the line auth.define_tables() is missing.

flobals -> globals
> ## in controller default.py
> def user():
> " to expose register, login, logout, etc "
> return dict(form=auth())
>
> @auth.requires_login()
> def data():

The above line is indented one character too much which results in an error.
> return dict(form=crud())
>
> @auth.requires_login()
> def download():
> " for downloading uploaded images "
> return response.download(request,db)

The above example is not (although stated) a complete app, even when
correcting the errors. No index action, no links to register, login,
etc, no functionality in the data action. If one has not already read
the web2py auth docu, one cannot understand what should be going on.
If I would have been looking at web2py for the first time, I would
have been disapointed and would not bother looking deeper. Also the
glued-together code style without spaces after colons and around
operators looks quite special. When suggesting PEP 8 compliance I
suggested using it in the *examples*, and just optionally in the gluon
code itself. The example and the documentation is the stuff people
are seeing and reading when trying to get started with web2py.
I know, the above paragraphs sound quite negative. *I* like web2py
very much and am a happy user. I just fear that such examples will
not draw new users towards this great project. Maybe use a simple
example without Auth the next time, which is *really* complete and
fully functional.
Kind regards,
Markus
