Django Cache cache.set Not storing data

Question

When I run python manage.py shell and then:

from django.core.cache import cache
cache.set("stack","overflow",3000)
print cache.get("stack")

(output: ) None

I tried restarting memcache, and here is what's in my settings:

CACHES = { 
  'default' : { 
     'BACKEND': 'django.core.cache.backends.memcached.MemcachedCache', 
     'LOCATION' : '127.0.0.1:11211',
  }
}

Answer 1

Make sure it's using the correct cache. Try from django.core.cache import caches, and then see the contents of caches.all(). It should just have one instance of django.core.cache.backends.memcached.MemcachedCache.
If it is, try accessing that directly, e.g.

from django.core.cache import caches  
m_cache = caches.all()[0]
m_cache.set("stack","overflow",3000)
m_cache.get("stack")

This might not solve your problem, but will at least get you closer to debugging Memcached instead of Django's cache proxy or your configuration.
