In Django, how to clear all the memcached keys and values?

Question

I don't want to restart the memcached server!

...or if you memcached is serving several applications and you do not want to destroy everything at once! — Stefano, Jan 13 '12 at 18:34

from django.core.cache import cache
cache._cache.flush_all()

Also see this ticket, it has a patch (that I haven't tested) to flush any type of cache backend: http://code.djangoproject.com/ticket/11503

For anyone who needs it, the cache lib is located in django.core.cache. So to run the command above, you need to import cache from django.core.cache import cache – kayluhb Aug 31 '12 at 14:46
I have `CACHE_MIDDLEWARE_ALIAS` pointing to a nondefault `memcached` cache but the command still tries to clear `default` and fails with `AttributeError: 'FileBasedCache' object has no attribute '_cache'` – int_ua Mar 23 '15 at 09:10

These days, you can use `from django.core.cache import cache; cache.clear()` – Shadow Jul 29 '15 at 03:39

And an one-liner from console:

echo "from django.core.cache import cache; cache._cache.flush_all()" | ./manage.py shell [--settings=myapp.settings_live]

An easiest and fastest way:

echo flush_all > /dev/tcp/localhost/11211
