Comment (by Daniel Hahler): Cool, working on a PR now. I've noticed that with SQLite, the "Extract" for a DurationField appears to return NULL/None always, e.g. with `DTModel.objects.annotate(duration_s=Extract('duration', 'second'))`. Should this throw some error instead? Would that be possible in `Extract` already (so basically keeping the current behavior there for unsupported backends)? Or would it need some other special casing? -- Ticket URL: <https://code.djangoproject.com/ticket/27473#comment:2> Django <https://code.djangoproject.com/> The Web framework for perfectionists with deadlines. -- You received this message because you are subscribed to the Google Groups "Django updates" group.
