johnny cache 1.4 in Django 1.6 does not work?

Question

I installed johnny-cache 1.4 in Django 1.6 using the instructions but does not work:

# add johnny's middleware
MIDDLEWARE_CLASSES = (
    'johnny.middleware.LocalStoreClearMiddleware',
    'johnny.middleware.QueryCacheMiddleware',
    # ...
)
# some johnny settings
CACHES = {
    'default' : dict(
        BACKEND = 'johnny.backends.memcached.MemcachedCache',
        LOCATION = ['127.0.0.1:11211'],
        JOHNNY_CACHE = True,
    )
}
JOHNNY_MIDDLEWARE_KEY_PREFIX='jc_myproj'

the error that comes out is:

$ python manage.py runserver

Investigate and say the problem is more of Django, I would like to fix it, because this is a great tool and it would be great help.

Same problem and I see it all over the internet. It has been 3 months since johnny cache was updated, maybe the project is dead in the water. — imns, Aug 28 '14 at 21:28

Upgrade to Django version 1.7 which updated today, continuing the same problem, what I did was upgrade to version johnny cache development:

johnny-cache==1.6.1a
python-memcached==1.53

with this I am resolved the problem temporarily until they update

Don’t use johnny-cache 1.6.1a, it’s broken with Django 1.6. The tests are passing but that doesn’t mean the tests are correct. – Bertrand Bordage Oct 09 '14 at 00:09

Johnny-cache became a mess, use [django-cachalot](https://github.com/BertrandBordage/django-cachalot) instead. I tried to fix johnny-cache, but ended up rewriting a new project… – Bertrand Bordage Oct 09 '14 at 00:10
