33011	my_model.manyrelation_set.all() return empty value	Floréal Cabanettes	nobody	"I have a problem which occurred since django 3.2 (no problem with django 3.1).

I use django rest framework. On the view, I have a model ""Run"" and a model ""Experiment"". On the view, I get experiments with :
my_experiments = my_run.experiment_set.all()

But since django 3.2, this returns an empty queryset. If I add a breakpoint in pycharm just after this line, the queryset is no more empty.

Also, this line works perferctly:
my_experiments = Experiment.objects.filter(run_id=my_run.id)

But I think the first code is more beautiful... so why this problem?
