How to Integrate Redis in Django?

Steps:
1.

pip install django-redis

Go to settings and add these lines

CACHES = {
    "default": {
        "BACKEND": "django_redis.cache.RedisCache",
        "LOCATION": "redis://127.0.0.1:6379/1", // Redis server running on your Machine 
        "OPTIONS": {
            "CLIENT_CLASS": "django_redis.client.DefaultClient",
        }
    }
}

For running redis server, istall msi from https://github.com/MicrosoftArchive/redis/releases Go to C drive then redis and then redis_cli Now, you have done setup
Go to your view.py file and add these lines at the top

from django.core.cache import cache

How it works?


def search(request):
    query = request.GET.get('query', '')
    if cache.get(query):
        product = cache.get(query)
        print("Cache hit")
    else:
        product = Product.objects.filter(Q(title__icontains=query)) | Product.objects.filter(Q(description__icontains=query))
        cache.set(query, product)
        print("Cache miss")
    return render(request, 'store/search.html',{
        'query':query,
        'products':product
        })

In this code, first we get query and then check if query key is available in the cache or not. If available then get it's value and assign it to the product Else You have to get the product value based on the query from the database.
