Where can a save confirmation page be hooked into the Django admin? (similar to delete confirmation)
I'm by no means a Django expert, so this answer might misguide you. 
Start looking somewhere around django.contrib.admin.options.ModelAdmin, especially render_change_form and response_change. I guess you would need to subclass ModelAdmin for your model and provide required behavior around those methods.
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out-of-date state.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!
