memcache on django is not working
celery, django, django-cache, memcached, python-memcached
Solution
The problem was, memcached was killed for some reason and I was assumed it was still running. My bad. Now it works all perfectly.
For anyone who is stuck on a similar problem you want to make sure you are still running memcached, try `memcached -vv`
Keeping this here for reference.
Problem
I have a race condition in `Celery`. Inspired by this - http://ask.github.io/celery/cookbook/tasks.html#ensuring-a-task-is-only-executed-one-at-a-time I decided to use memcache to add locks to my tasks. These are the changes I made: ``` python-memcached # settings for memcache CACHES = { 'default': { 'BACKEND': 'django.core.cache.backends.memcached.MemcachedCache', 'LOCATION': '127.0.0.1:11211', } } ``` After this I login to my shell and do the following ``` >>> import os >>> import django >>> from django.core.cache import cache >>> os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'proj.settings.base') >>> cache <django.core.cache.DefaultCacheProxy object at 0x101e4c860> >>> cache.set('my_key', 'hello, world!', 30) #display nothing. No T/F >>> cache.get('my_key') #Display nothing. >>> from django.core.cache import caches >>> caches['default'] <django.core.cache.backends.memcached.MemcachedCache object at 0x1048a5208> >>> caches['default'].set('my_key', 'hello, world!', 30) #display nothing. No T/F >>> caches['default'].get('my_key') #Display nothing. ``` also did `pip install python-memcached` Using `Python 3.6`, `Django==1.10.5` What am I doing wrong? Any help will be appreciated.
