Thank you so much for replying! Let’s me share more about my context.
I’m creating a signal post_delete that logs the deleted objects to console.
For example:
- Project P has been deleted.
- Exporter E of Project P has been deleted.
- Farm F of Project P has been deleted.
When I tried deleting a project, first two logs worked but the third one throwed an exception DoesNotExist, when it tried to access farm.project.name.
After debugging, I think the root cause is because the order of deletion is Exporter → Project → Farm. The Project was deleted before Farm’s deletion so that the Farm cannot access its Project when it was deleted.
Therefore, I expect the order of deletion should be (Exporter, Farm) → Project, and I wonder if we have any simple solution to do that.
