can't get memcache value in dev console memcache viewer

I am setting cache properly as my project does grab the correct result from it. I want to view it in the dev console memcache viewer (http://localhost:8080/_ah/amdin/memcache) But when I paste in the key, it says "no such key". The memcache statement I use is:

stuff=memcache.get(userid, namespace='bo开发者_开发百科ok')

So when I use the userid (aka key) in the memcache viewer, it fails. Am I to somehow add the namespace? I tried that and that failed. I also tried the entity key, that was a fail. any ideas?!?

To the best of my knowledge you can't retrieve a namespaced memcache key using the dev console memcache viewer.

You have more than an option though:

a. Use the interactive console with a code like this:

from google.appengine.api import memcache  
print memcache.get(youruserid, namespace='book')

b. Create an admin section (Webapp+memcache api) to your web application adding this feature
