hi,
i store rows query in the session, and want to remove it, is it need two
step for that?
e.g.
def purchase_return_form():
form = SQLFORM(db.purchase_return_header)
if form.validate():
session.purchase_return_header = dict(form.vars)
rows = db(db.purchase_order_detail.purchase_order_no ==
session.purchase_return_header['purchase_order_no']).select()
*session.purchase_return_detail = rows.as_list() # store session as
list()*
return dict(form = form)
def empty_return_0(session_return_header, session_return_detail,
redirect_cart):
session_return_header.clear()
# step one delete all except i = 1
for i, row in enumerate(session_return_detail):
del session_return_detail[i]
# step two delete i = 1
for i in xrange(0, len(session_return_detail) ):
del session_return_detail[i]
redirect(URL(redirect_cart) )
the problem is if i just use one all value that store in session detail is
not deleted all, always remain i=1, so that i must take two steps for that.
is it the correct way to handle it in web2py?
thanks and best regards,
stifan
