the previous is not work, it's work first because it still store the
previous session, after clean session, cache and error it's not work.
something strange in here.
e.g.
*controllers*
session.sale_order_net = session.sale_order_net or {}
#session.sale_order_net[0] = dict(discount = 0, delivery_fee = 0,
packing_fee = 0, stamp_fee = 0, paid = 0)
session.sale_order_net[0] = 0, 0, 0, 0, 0
*modules*
if current.request.vars.action == 'adjust_total_net':
discount = int(current.request.vars['discount'] )
delivery_fee = int(current.request.vars['delivery_fee'] )
packing_fee = int(current.request.vars['packing_fee'] )
stamp_fee = int(current.request.vars['stamp_fee'] )
paid = int(current.request.vars['paid'] )
#current.session.sale_order_net[0] = dict(discount = discount, delivery_fee
= delivery_fee, packing_fee = packing_fee, stamp_fee = stamp_fee, paid =
paid) # not work
current.session.sale_order_net[0] = discount, delivery_fee, packing_fee,
stamp_fee, paid # not work
whether i store the session as dict() or list it still not update, i'm not
using the variable to represent the session in the module (explicit it the
session name and place [0] ), n it still not update, no error traceback
occured, but the result is not expected (check with response.toolbar() the
value is still 0 )
i know i missed something but can't figure it out, any idea how to face
this using web2py way?
thanks and best regards,
stifan
