[SOLVED] Django caching with Redis

Django caching with Redis

I have implemented django caching using redis following this blog: https://realpython.com/caching-in-django-with-redis/

So I followed this, installed the package, Added in

CACHES = {
"default": {
    "BACKEND": "redis_cache.RedisCache",
    "LOCATION": "redis://127.0.0.1:8000/",
    "OPTIONS": {
        "CLIENT_CLASS": "django_redis.client.DefaultClient"
    },
    "KEY_PREFIX": "example"
}

}

Then in views.

from django.conf import settings
from django.core.cache.backends.base import DEFAULT_TIMEOUT
from django.views.decorators.cache import cache_page

CACHE_TTL = getattr(settings, 'CACHE_TTL', DEFAULT_TIMEOUT)

and then added the decorator for the function

@cache_page(CACHE_TTL)
@login_required_dietitian
def patient_profile(request, id):
    data = {}
    return render(request, 'profile.html', {'data':data})

And then I am getting this error while I run the server

redis.exceptions.ConnectionError: Connection closed by server.

I am new to such caching technique, Any suggestion how to resolve this issue?

Solution

Your configuration specifies Redis on port 8000, Redis, by default, runs on port 6379. Looks like its trying to connect your Django app, hence the Connection Error. Redis runs as a separate process, listening for requests on port 6379.
