Here is what I'm talking about:
def update_something():
fields = [Field('name'),
Field('address', 'text'),
Field('city'),
Field('state'),
Field('zip_code')]
form = SQLFORM.factory(*fields)
if form.process().accepted:
# update the database here
return dict(form=form)
After the first time a user updates a record, I want the value of 'state'
to remain and everything else go back to the defaults. I know I can do it
by adding some code after form.process().accepted to save the value to the
session, and then check it before defining the fields, but 'form' doesn't
exist yet.
I still think I must be missing something here....
