Repost <http://stackoverflow.com/q/17901525/2626200>.
I can't solve problem with SQLFORM update. I need to compute some field
(`field_gen`), and be sure, that form filled by an user will be inserted in
the same record. This form;
form = SQLFORM(db.tab1, \
fields=['field1','field_gen'], \
)
works fine, but this;
f1 = db.tab1.insert(field_gen='something')
form = SQLFORM(db.tab1,record=db.tab1(f1),showid=False, \
fields=['field1','field_gen'], \
)
can't be accepted by:
form.process().accepted
I get:
form.errors -> <Storage {}>
It is probably similar problem, but with
CRUD<http://stackoverflow.com/questions/14553594/web2py-custom-forms-are-not-being-submitted>,
but I already use SQLFORM...
Also according to web2py
manual<http://web2py.com/books/default/chapter/29/07/forms-and-validators#SQLFORM-and-insert/update/delete>it
should work... I think. My example is part of some slightly bigger web
application developed for GAE, so maybe the problem is in some other
part... but where to look for it???
Table definition is:
db.define_table('tab1',
Field('field1','string'),
Field('field_gen','string'))
Changes with parameters `writable` and `readable` doesn't change anything...
Using of `default` or `compute` is also impossible, because `field_gen`
have to be calculated based some parameters of current session and already
existed `field_gen` records.
I suppose, that such behavior can be obtained in some other ways, but the
proposed one seems to be the shortest and easiest... and according to the
manual<http://web2py.com/books/default/chapter/29/07/forms-and-validators#SQLFORM-and-insert/update/delete>...
should work...
Thank you in advance for your help.
