Unpersisted occurrences don't work

[h3x4git]

#301
This is still an issue. Unpersisted occurrences, whether their event has a frequency rule declared or not, they still give you this error. I haven't been able to see this working yet. Persisted occurrences work fine.

I'm using version 0.10.1 on test, development and production environment. Versions of Django tested: 4.1.7 (test), 3.2.16 (dev and production)

Maybe there is some bug?

The class-based view that fails is OccurrencePreview , I also tried to add a DetailView mixin. I couldn't get it to create an "object" attribute, not even by using super().get_object()

May I kindly ask anyone if this feature works for them and under which versions of this package and Django?

I'm running out of ideas

@h3x4git I've just opened a pull request that should fix this issue here:

#555

Would appreciate it if you would be able to check out that branch to see if it fixes your issue. Many thanks

Hello, I tried your fix and I don't get the AttributeError anymore. I get a Not Found error now, but I'm customizing django-scheduler URLs in this project so I don't think this is related to your fix. I tried your code both in production and in the development environment: no AttributeError at all, I think you solved the problem! Thank you for your work and for the heads-up

I checked and it seems I get the IndexError exception of line 183 inside get_object of OccurrencePreview. The URL path calling the view is the same as the original, it just comes after one further string for a more meaningful URL structure (I added "calendar/"). The path in this example is /calendario/occurrence/2/2023/7/11/2/2/15/

The branch is ready to merge. @fatboystring, what do you think about @h3x4git comments?

[h3x4git]

The issue is with another PR I had already applied #488. That URL path I mentioned seems to work fine on a test project, where the only difference with the one giving errors is I didn't use neither django-polymorph onto the Event table nor the Abstract model base setting. I started anew with the abstract version to make sure there was no contamination between environments. With the original Event model it works.

Any news, anyone? I looked into it but I don't see how the event = get_object_or_404(Event, pk=self.kwargs["event_id"]) inside the OccurrencePreview class view would not be compatible with and Abstract model base.. what will the course of action be? Will you only merge one of the two PRs?
