I'm not sure if I'm doing something wrong, or if it's a bug in web2py,
but I get an interesting ticket when I try tu submit a new news into
my database. Any sudgestions?

The controller function is:
***
@auth.requires_login()
def nowa_wiesc():
form = SQLFORM.factory(
SQLField('tytul', requires=[IS_NOT_EMPTY(), IS_NOT_IN_DB(db,
db.strona)]),
SQLField('tresc', 'text', requires=IS_NOT_EMPTY()),
SQLField('zrodlo', length=2000, requires=IS_NULL_OR(IS_URL
())),
labels={'tytul':'Tytuł', 'tresc':'Treść wieści',
'zrodlo':'Link do źródła'})
if form.accepts(request.vars, session):
strona_id = db.strona.insert(
tytul=form.vars.tytul,
adres=CLEANUP(form.vars.tytul),
tresc=form.vars.tresc,
statyczna=False
status=2)
wiesc_id = db.wiesc.insert(
strona=strona_id,
zrodlo=form.vars.zrodlo)
db.wiesc_glos.insert(wiesc=wiesc_id)
redirect(URL(r=request, f='wiesc', args=CLEANUP
(form.vars.tytul)))
return dict(formularz=form)
***
And my model is:
***
db.define_table('strona',
SQLField('tytul'),
SQLField('adres'),
SQLField('statyczna', 'boolean'),
SQLField('tresc', 'text'),
SQLField('kto', db.auth_user),
SQLField('kiedy', 'datetime'),
SQLField('status', 'integer'))
db.strona.tytul.length = 120
db.strona.tytul.requires = IS_NOT_EMPTY()
db.strona.adres.requires = IS_NOT_EMPTY()
db.strona.kto.default = auth.user.id if auth.user else 0
db.strona.kto.writable = False
db.strona.kiedy.default = request.now
db.strona.kiedy.writable = False
db.define_table('wiesc',
SQLField('strona', db.strona),
SQLField('zrodlo'))
db.wiesc.zrodlo.length = 2000
db.define_table('wiesc_glos',
SQLField('kto', db.auth_user),
SQLField('kiedy', 'datetime'),
SQLField('wiesc', db.wiesc))
db.wiesc_glos.kto.default = auth.user.id if auth.user else 0
db.wiesc_glos.kto.writable = False
db.wiesc_glos.kiedy.default = request.now
db.wiesc_glos.kiedy.writable = False

I also think I should explain some conventions:
- the table 'strona' conatins generally all type of pages content
(articles, news etc),
- 'tytul' means 'title',
- 'tresc' means 'content',
- 'adres' means 'adres' ;) (I use that for a cleaned version of the
title which I use in URLs),
- 'statyczna' means 'static' (true if it's not any 'special' page
type like an article, a news etc),
- 'kto' means 'who',
- 'kiedy' means 'when',
- 'status' can have 3 values: 0 means that the page is a draft, 1
that it is private, 2 that it is public,
- the table 'wiesc' contains news (the shared functionality of
different page types is put into 'pages' - that's somewhat similiar to
the 'nodes' idea in Drupal, if you're familiar with it),
- 'strona' is of course a refference to a page,
- 'zrodlo' contains a URL which is the source of the news,
- the users can vote on news - it should work somewhat similiar to
digg - that's what the 'wiesc_glos' table is for,
- 'kto' means 'who' (the user who voted),
- 'kiedy' means 'when' (when the vote was made, I'm not really sure
if I need this one...),
- 'wiesc' is (as you can see) a relation with a news (the news that
the user votes for).
(Jeez, I have to switch to english names, or it'll be a pain in the
ass to ask for help here more frequently. ^^)
What I'm trying to do in the controller is to create a new news (which
needs a page). I also assume that the news author would vote on the
news, so I do that automatically. The problem seems to be with the
'form.accepts' call. Am I doing something wrong with it?
Cheers!
