I am trying to find it it was actually in the mailing list a discussion about
it and the suggestion was to use the default.

Maybe I just do it plain wrong :-)
form = SQLFORM(db.lvstorage)
form.vars.lunid = 2 # Does not work
Thats how I did it.
Now I have a complicated system :) My goal is/was to make the lunid
autoincrement with each submit.
Now I use this (btw I am not a programmer so, suggestions are always welcome.)
if not request.vars.newrecord: # For the newrecord button
newrecord = False
if request.vars.newrecord: # For the newrecord button
session.lunid = 2
newrecord = True
if not request.args or newrecord == True: # If called directly from
menu or newmenu button
if session.lunid == 2:
# Default settings for the page
db.lvstorage.lunid.default = 2
db.lvstorage.setup_id.default = 1
db.lvstorage.lvsize_id.default = 2
db.lvstorage.storagemap_id.default = 1
session.setup_id = 1
session.storagemap_id = 1
session.lvsize_id = 2
else:
if session.lunid == 31: # Lunid 31 is managed by the
controller so skip it
session.lunid = 32
if request.vars.setup_id : # To make sure that if the var does
not exist it will not change the session var
session.setup_id = request.vars.setup_id
if request.vars.lvsize_id :
session.lvsize_id = request.vars.lvsize_id
if request.vars.storagemap_id :
session.storagemap_id = request.vars.storagemap_id
db.lvstorage.lunid.default = int(session.lunid)
db.lvstorage.setup_id.default = session.setup_id
db.lvstorage.lvsize_id.default = session.lvsize_id
db.lvstorage.storagemap_id.default = session.storagemap_id
if request.vars.checkbox: # If checkbox is used do not increase
lunid
pass
else:
session.lunid = int(session.lunid) + 1 # Increase lun id
form = SQLFORM(db.lvstorage)
