As the title says, it would be nice to show a confirmation page to the User when he intends to create or change instances on a ModelAdmin form.

At the moment a confirmation page is shown to the User only when a specific instance is going to be deleted. The same approach used in _delete_view(*args) could be introduced into _changeform_view(*args).

A User specific use-case could be:

  • The User specifies a ModelAdmin and overrides save_model(*args) to execute further operations after changes are saved to database, like executing Celery tasks
  • On the Admin frontend, the User wants to be sure that he's not going to submit the form wrongly.

The confirmation page could be shown optionally, a User could set a boolean variable on the admin class, like ask_confirmation or something similar, and accordingly to that variable, Django would show or not the confirmation/preview page.

I don't see a wide usage of confirmation pages when adding/editing objects. I see your use case but it's niche, IMO. We shouldn't ask users to confirm everything. Moreover an implementation can be tricky and error-prone. I don't think we should add a "big" features that would be disabled by default.
