Comment (by Simon Charette): A regression test for the above optimization could be to `assertNumQueries(1)` on the `b.a.add(str(pk))` call when a `m2m_changed` signal is registered for the relationship. That is to disable the ''fast'' insertion mechanism that is enabled on all backends except for Oracle. -- Ticket URL: <https://code.djangoproject.com/ticket/8467#comment:15> 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.
