I don't use factory, so I don't know if it has special requirements for
this, but here's a snippet I use on an ordinary SQLFORM:
db.run.distance.readable = False
db.run.duration.readable = False
form = SQLFORM(db.run,linkto=link)
if form.process().accepted:
(etc)
For another form in the same app:
if request.vars.startseg:
db.segment.isstart.default = (request.vars.startseg == 'T' )
db.segment.isstart.readable = db.segment.isstart.default
db.segment.isstart.writable = db.segment.isstart.default
form = SQLFORM(db.segment)
if form.process().accepted:
I hope this helps.
