The following is an improved version for the accepted solution does not consider the request parameters.

decorator_of_cache_per_user.py

from django.core.cache import cache as core_cache

def cache_key(request):
    if request.user.is_anonymous():
        user = 'anonymous'
    else:
        user = request.user.id

    q = getattr(request, request.method)
    q.lists()
    urlencode = q.urlencode(safe='()')

    CACHE_KEY = 'view_cache_%s_%s_%s' % (request.path, user, urlencode)
    return CACHE_KEY

def cache_per_user_function(ttl=None, prefix=None, cache_post=False):
    def decorator(function):
        def apply_cache(request, *args, **kwargs):
            CACHE_KEY = cache_key(request)

            if prefix:
                CACHE_KEY = '%s_%s' % (prefix, CACHE_KEY)

            if not cache_post and request.method == 'POST':
                can_cache = False
            else:
                can_cache = True

            if can_cache:
                response = core_cache.get(CACHE_KEY, None)
            else:
                response = None

            if not response:
                response = function(request, *args, **kwargs)
                if can_cache:
                    core_cache.set(CACHE_KEY, response, ttl)
            return response
        return apply_cache
    return decorator
