How to cache views in django

I am currently using django and I'm attempting to cache my view like so 

from django.views.decorators.cache import cache_page

@cache_page(60 * 15)
def index(request):
   # This method takes time to run, which is why I need to cache this view
   a_method_that_preforms_heavy_db_transactions()

   context_dict={'Models': Model.objects.all()} 
   return render(request, 'webapp/index.html', context_dict)

I have a_method_that_preforms_heavy_db_transactions() In just to test the loading time to see if it cached the view but the loading time time doesn't change when its supposed to be "cached" and I'm unsure why this is my settings.py

 CACHES = {
    'default': {
    'BACKEND': 'django.core.cache.backends.memcached.MemcachedCache',
    'LOCATION': 'My_computers_ip_address:11211',
   }
}

You'll need to add a caching service, e.g Memcached

CACHES = {
    'default': {
        'BACKEND': 'django.core.cache.backends.memcached.MemcachedCache',
        'LOCATION': '127.0.0.1:11211/A_ROUTE_WITH_A_HEAVY_TRANSACTION',
    }
}

You'll find everything you need here:

Have you set caching up? You need to define CACHES in your settings.py file. You can use memcached, Redis, your database or a file system. The simplest setup is with local memory as it doesn't require any external services:

CACHES = {
    'default': {
        'BACKEND': 'django.core.cache.backends.locmem.LocMemCache',
        'LOCATION': 'unique-snowflake',
    }
}
