        ) + super(ButtonableModelAdmin, self).get_urls()


class MyModelAdmin(ButtonableModelAdmin):

    def _ping_google(self, request, queryset):
        try:
            ping_google()
            messages.success(
                request,
                'Sitemaps were submitted.')
        except Exception:
            messages.warning(
                request,

    _ping_google.short_description = 'Ping google'

    buttons = [(_ping_google.func_name, _ping_google.short_description)]

The ping_google() command only works if you have registered your site with Google Webmaster Tools.
