The original book had:
<quote>
When editing an existing person, the appadmin UPDATE form shows a link
to a page that lists the dogs that belong to the person. This behavior
can be replicated using the linkto argument of the SQLFORM. linkto has
to point to the URL of a new action that receives a query string from
the SQLFORM and lists the corresponding records. Here is an example:
def display_form():
record = db.person(request.args(0)) or redirect(URL('index'))
url = URL('download')
link = URL('list_records')
form = SQLFORM(db.person, records, deletable=True, upload=url,
linkto=link)
if form.accepts(request.vars, session):
response.flash = 'form accepted'
elif form.errors:
response.flash = 'form has errors'
return dict(form=form)
</quote>
So the questions are:
- Why was this changed?.
- Does anybody use it this way?.
