Added test for LogEntry.get_edited_object(); refs #24244.

        logentry.content_type.model = "non-existent"

        self.assertEqual(logentry.get_admin_url(), None)

    def test_logentry_get_edited_object(self):

        "LogEntry.get_edited_object returns the edited object of a given LogEntry object"

        logentry = LogEntry.objects.get(content_type__model__iexact="modelwithstringprimarykey")

        edited_obj = logentry.get_edited_object()

        self.assertEqual(logentry.object_id, str(edited_obj.pk))

    def test_deleteconfirmation_link(self):

        "The link from the delete confirmation page referring back to the changeform of the object should be quoted"

        response = self.client.get(reverse('admin:admin_views_modelwithstringprimarykey_delete', args=(quote(self.pk),)))
