Ticket #26638 added support for accepting callables in the 'defaults'
parameter of get_or_create and update_or_create. In the case where
update_or_create is updating, the callables are not evaluated. I have
written a test for update_or_create that demonstrates this behavior
(attached).
Here is the traceback for that test failure:
{{{
