That's the issue really - whether my design lends itself to self-submisson
and if not whether not using those features of web2py that are built around
self-submission rather reduce the benefits of using web2py at all.
It's not that I cannot see a way to use self-submission but there are then
oddities - well they seem so to me - I notice that the book says:
"Pre-populating the form
It is always possible to pre-populate a form using the syntax:
form.vars.name = 'fieldvalue'
Statements like the one above must be inserted after the form declaration
and before the form is accepted, whether or not the field ("name" in the
example) is explicitly visualized in the form."
and to use the example from a few lines earlier:
def display_form():
record = db.person(request.args(0)) or redirect(URL('index'))
url = URL('download')
link = URL('list_records', args='db')
form = SQLFORM(db.person, record, deletable=True,
upload=url, linkto=link)
# pre-population would go here ?!
if form.process().accepted:
response.flash = 'form accepted'
elif form.errors:
response.flash = 'form has errors'
return dict(form=form)
in the example that I was thinking about that would involve a couple of DB
reads followed by the form.vars... assignments. Now if the same code is
then executed after submission how do these statements get handled ? I can
only suppose that re-executing the form=SQLFORM(...) has some magic in it,
but presumably not in the DB access and the form... assignments.
How does it deal with those ?
I've been otherwise occupied in the past few days and still haven't
actually done any work wit web2py yet...
