Comment (by Matthias Kestenholz): I just hit this as well. The solution (workaround) seems to be using `F()` and `Value()` freely and consistently for all querysets even if it doesn't look necessary on the surface. See https://github.com/matthiask/feincms3-forms/commit/c112a7d613e991780f383393fd05f1c84c81a279 (It's a bit surprising that `values_list` doesn't produce a SQL query with the exact same ordering of values, but after thinking about it some more I'm not sure if that's really a bug or just a sharp edge of the current implementation.) -- Ticket URL: <https://code.djangoproject.com/ticket/28553#comment:6> 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.
