I'm just learning web2py and I've got a simple example whose behavior
I don't understand. I've got a page with a form on top that sets a
session variable holding the default year.
On the bottom of the page I've got an SQLTABLE where the records
selected should be from the
selected year. What I'm observing is that the form on top accepts
the year value and the bottom of the page updates but the form on top
always seems to be one update behind.
In the controller:
def admin_test():
# form1 sets the default year to work on
if not session.bene_year:
session.bene_year = datetime.datetime.now().year
form1 = FORM('Set Year (current value is '+session.bene_year+') :
',
INPUT(_name='year', _value=session.bene_year,
requires=IS_NOT_EMPTY()),
INPUT(_type='submit'))
# set the default year from the form
if FORM.accepts(form1, request.post_vars, session,
formname='form_one'):
session.bene_year = request.post_vars.year
# set the year
response.flash = 'The default year is set to
'+session.bene_year
# fetch the current beneficiaries for the default year
dbrecords = db(db.beneficiary.year==session.bene_year).select
(db.beneficiary.ALL)
records = SQLTABLE(dbrecords, truncate='1024')
return dict(form1=form1, dbrecords=dbrecords, records=records)
The sequence I'm observing is:
1) Initial page view, year is set to 2009. All OK.
2) Enter 2007 and press 'Submit Query'. Page refreshes, db records
from 2007 appear below, and
form one reads: "Set Year (current value is 2009) : [ 2009 ]".
Not OK.
3) Replace 2009 with 2005 and press 'Submit Query'. Page refreshes, db
records from 2005 appear below and the form now reads: "Set Year
(current value is 2007): [ 2007 ]".
4) etc.
Thanks!
