There might have been some confusion. You don't have to break your form or
pages into multiple steps. But you can break the code in your controller
into different steps. One controller can work with multiple tables.
You can do stuff like:
form_car = SQLFORM(db.car)
form_customer = SQLFORM(db.customer)
if form_car.accepts(request.vars, session, dbio=False):
if form_customer.accepts(request.vars, session, dbio=False):
do something
return dict(form_car=form_car, form_customer=form_customer)
You might need to use dbio=False so that Web2py doesn't automatically update
the database. This can all be done on one web page.
