Hi thanks a lot for the help, i put this code in my model, and it runs
fine.
inventory=db().select(db.Inventory.ALL)
for i in inventory:
if db((i.idProducto==db.Inventory.idProduct)&
(i.idCountry==db.Inventory.idCountry)).count()>1:
db(db.Inventory.id == i.id).delete()
However I'd like to learn how modify the class becouse i think is the
best way to do it. I can't understand the code a lot. So please,
how do i edit this code for settings the id of the current record you
can prevent the check on update?
def set_self_id(self, id):
self.record_id = id
