Save object immediately when adding via admin panel?

Question

Django

I ran into a problem: you need to save the model object immediately after the user goes to the /add/ page in the admin panel. That is, so that it already has a primary key (committing to the database is not critical).
Roughly speaking, I need object_id and content_type_id, which in the standard implementation are available only when "editing" an object, and not when adding it.
Tried to do it via post_init signal, but for some unknown reason it creates multiple objects, not just one.
Ideas?

Override the form for ModelAdmin
