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?
