Comment (by Morgan Wahl): Thanks for looking at this Simon. I should've been a bit clearer about the problem: on the instance return from `refresh_from_db`, *every access of the GFK attribute* produces a *different instance* of the related object. (I tried to show that with the `id(ref.obj) == id(ref.obj)` line). I called `refresh_from_db` just to simulate a real-world situation where the row backing the `ref` instance here is created at some point, and at some later point a new model instance is instantiated for that row. -- Ticket URL: <https://code.djangoproject.com/ticket/28856#comment:4> 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.
