Hi friends!!!

Please, i have tried this function to get the last date of an invoice of a partner:


def get_last_invoice_period(self, cr, uid, ids, partner_id, context = None):

invoice_table = self.pool.get('account.invoice')

momo_ids = invoice_table.search(cr, uid, [('partner_id', '=',partner_id)])

vals = invoice_table.read(cr,uid,momo_ids,['date_due','date_invoice','commercial_partner_id'],context=context)

print vals

ref_id = False

y = False

m = False

d_ref = datetime.strptime("2011-01-01","%Y-%m-%d")

for v in vals :

d_to = datetime.strptime(v['date_invoice'],"%Y-%m-%d")

if d_ref < d_to :

d_ref = d_to

ref_id = v['id']

y = d_to.year

m = d_to.month

print ref_id

print y

print m

return (str(y),str(m),ref_id)

But, i got this error: AttributeError: 'module' object has no attribute 'strptime' despite the fact that i have added :

from datetime import datetime, date, time

Please,who can help me i have tried this:

d_ref = datetime.strptime("2011-01-01","%Y-%m-%d")
print d_ref

and i have got:  2011-01-01 00:00:00

Please help and Thanks a lot.
