Weird behaviour when using queryset class attributes and overriding get_queryset
Summary
On some views, we use the queryset class attribute together with an overridden get_queryset method. When using the queryset class attribute inside the overridden get_queryset method, there are some strange behaviors to observe. It seems like referencing self.queryset in the get_queryset method leads to some sort of cache invalidation.
What is the expected correct behavior?
Calling get_queryset should always return an up-to-date query resembling the current database's state.
Possible fixes
- Don't use queryset attributes and get_queryset together
- find out how the original get_queryset works, then maybe update the queryset saved in the class attribute before further processing
