hi,
is it possible to temporary store the uploaded file in session?
e.g.
import os
def form_1(session_order, link_form, link_checkout):
form = SQLFORM.factory(
Field('detail_account', 'reference detail_account',
requires = IS_IN_DB(current.db,
current.db.detail_account.id, current.db.detail_account._format,
orderby = current.db.detail_account.name) ),
Field('amount', 'integer', requires = IS_NOT_EMPTY() ),
* Field('cash_out_document', 'upload', requires = IS_NOT_EMPTY(), *
* uploadfolder = os.path.join(current.request.folder, 'static',
'temp_document') ),*
)
if form.process().accepted:
current.response.flash = current.T('Form accepted')
id = int(current.request.vars.detail_account)
amount = int(current.request.vars.amount)
* cash_out_document = current.request.vars.cash_out_document*
* session_order[id] = amount, cash_out_document*
redirect(URL(link_form) )
elif form.errors:
current.response.flash = current.T('Form has errors')
return dict(form = form, link_checkout = link_checkout)
what i want to achieve is to store one or many document in the session,
after checkout and confirm all is complete it will insert into database and
clear the session. is it possible to achieve it using web2py way?
when i tried it return an error :
