The problem in the second code is that f1 = form().process() so f1 is a
procesed form but then you call f1.process() again. Also f1 is not returned
which means it is not displayed. If it is not displayed it is not
processed, and if not processed it is not accepted.
This should work:
def myform():
form = SQLFORM.factory(Field('client'), Field('portfolio'))
return myform.process()
def sandbox():
f1 = myform()
if f1.accepted:
f2 = 'rhubarb'
else:
f2 = []
return dict(f1=f1, f2=f2)
You can do it with classes too but I do not think it buys you anything
since you do not need to call process from a separate method than the one
that generate the form.
