still face the same error :
e.g.
db.define_table('default_size',
Field('name'),
Field('length_in_cm', 'double'),
Field('width_in_cm', 'double'),
Field('total_square_meter', 'double'),
Field('acquisition_price', 'integer') )
db.default_size.total_square_meter.compute = lambda r:
(float(r['length_in_cm'] ) * float(r['width_in_cm'] ) ) / 10000
def __after_insert_purchase_order_detail(f, id):
db(db.default_size.id == f.default_size).update(acquisition_price = f.price)
db.purchase_order_detail._after_insert.append(__after_insert_purchase_order_detail)

is there any way to face this?
thanks and best regards,
