I tried 4.2a1 today on my project and I noticed pagination was broken on
one view.
After little investigation I manage to reproduce an error:
`Event` is a model with `set` a Foreignkey
{{{
>> events = Event.objects.all()
>> events_without_set = events.filter(set__isnull=True)
>> one_event_of_each_set = (
events.filter(set__isnull=False)
.order_by("set_id")
.distinct("set_id")
)
>> my_list = events_without_set.union(one_event_of_each_set)
>> my_list.count()
212
>> my_list[2]
Traceback (most recent call last):
File "<console>", line 1, in <module>
File "/venv/lib/python3.11/site-packages/django/db/models/query.py",
line 450, in __getitem__
return qs._result_cache[0]
~~~~~~~~~~~~~~~~^^^
IndexError: list index out of range
}}}
