[Python] Where can a save confirmation page be hooked into the Django admin? (similar to...

I want to emulate the delete confirmation page behavior before saving certain models in the admin. In my case if I change one object, certain others should be deleted as they depend upon the object's now out-of-date state.

I understand where to implement the actual cascaded updates (inside the parent model's save method), but I don't see a quick way to ask the user for confirmation (and then rollback if they decide not to save). I suppose I could implement some weird confirmation logic directly inside the save method (sort of a two phase save) but that seems...ugly.

Any thoughts, even general pointers into the django codebase?

Thanks!
