Django admin: redirect to object change page if only one exists in list

Question

I'm using Django for an application, and wondering about an option in the admin. Is it possible for django admin to redirect to the details page of an object, if only one exists in the list view?

For example, if only this object exists:

redirect immediately to the change view on this object, without needing the user to click on the object.

I'm not using any custom view. I couldn't find any solution after 2 hours of search.

Thanks!

You can try this

def changelist_view(self, request, extra_context=None):
    if self.model.objects.all().count() == 1:
        obj = self.model.objects.all()[0]
        return HttpResponseRedirect(reverse("admin:%s_%s_change" %(self.model._meta.app_label, self.model._meta.model_name), args=(obj.id,)))
    return super(ItemAdmin, self).changelist_view(request=request, extra_context=extra_context)

Also check changelist_view parameters based on django version.
