new to django/python developement, can't get this one figured out. I have a model that has a couple DateFields (issued_date & completion_date), and I'm trying to return a value with the difference of the two on each entry that is complete, and then if it isn't completed yet, show the amount of days since it was issued. I am using the Admin interface and what I have in the model is this....
models.py class RequestTicket(models.Model): . . . issued_date = DateField() completed_date = DateField(blank=True, null=True) def days_old(self): complete = RequestTicket.object.filter(completion_date__isnull=False) for ticket in complete: return ticket.completion_date - ticket.issued_date return date.today() - self.issued.date days_old.short_discription = 'Days Old' what i get returned is if the first entry was completed within 2 days (issued=9/14, completed=9/16), all entries after that get 2 days, even if there is no completion date. If i use 'self.object.filter(completion_date__isnull=False)', I get a NONE answer on all entries If I don't filter for just completed entries I get an error trying to subtract NoneType field with DateField, i guess that might be from the NULL setting. Any help, advice would be great, or if i need to post in another area.
