class Command(BaseCommand):
help = (
"Can be run as a cronjob or directly to clean out expired sessions "
"when the backend supports it."
)
def handle(self, **options):
engine = import_module(settings.SESSION_ENGINE)
try:
engine.SessionStore.clear_expired()
except NotImplementedError:
raise CommandError(
"Session engine '%s' doesn't support clearing expired "
"sessions." % settings.SESSION_ENGINE

> Django provides a clean-up management command for this purpose: clearsessions. It’s recommended to call this command on a regular basis, for example as a daily cron job.
然後 cleansession 的話，如果擔心自己砍會出事，可以自己追你 config 裡面用的 SESSION_ENGINE 裡面的 clear_expired() 函數
