When deleting objects through the admin interface ProtectedError exceptions aren't handled. This patch catches such exceptions and displays an error message instead.

Is this error present on 1.6 and/or master? Is the issue different from #19838? A regression test will be required in order to commit the fix.

Replying to timo:

I can't see ProtectedError being handled anywhere in actions.py in master.

It does not appear to the be the same as #19838; this ticket looks like it's for "delete all selected" dropdown from the top of the page.

The good thing is, there does appear to be some protection in place already. You have to go through an intermediate page to confirm, and if a protected (nested) object is detected, then the button to confirm deletion is simply not there, so you normally can't do a delete.

You can still trigger the ProtectedError by skipping the intermediate page, that might be what happened here. The other possibility is that the check for protected via get_deleted_objects is missing something (but without more information that'll be harder to track down)

As far as I know that intermediate page has nothing to do here.

Closing as needsinfo absent additional details from the reporter.

Summary: Admin doesn't catch ProtectedError → admin's delete_selected action doesn't catch ProtectedError

You can create a crash by posting data and bypassing the confirmation page. Seems low priority given the admin is for "trusted users" but wouldn't hurt to fix. See #26235 for the same issue for the regular delete view.
