Comment référencer une variable django en javascript?

Question

Je travaille sur un projet qui nécessite que j'utilise une valeur contenue dans une variable de mon template view.py. J'ai besoin d'utiliser cette variable dans mon javascript. Est-ce que quelqu'un sait comment passer une variable de django à JS?

Voici ma fonction dans views.py

@login_required 
@never_cache_headers 
def user_feed(request, user=None, extension=None): 
# Ensure we have a user 
if user is None: 
    user = request.user 
    prof = user.get_profile() 
elif isinstance(user, basestring): 
    user = get_object_or_404(User, id=user) 

# Build author list 
author_ids = [] 
author_ids.append(user.id) 

# Check if user if friend to profile being viewed 
are_friends = Friendship.objects.are_friends(user, request.user) 

# Determine Date 
now = datetime.datetime.now() 
today = now.date() 
if now.time() < datetime.time(3): 
    start_dt = datetime.datetime.now() - datetime.timedelta(hours=settings.FEEDITEM_BUFFER_HOURS) 
else: 
    start_dt = datetime.datetime(today.year, today.month, today.day) 

# Build up the where query 
where = [] 
if user.id != request.user.id: 
    where.append({'ping_type':'public'}) 
    if are_friends: 
     where.append({'ping_type': 'friends_only'}) 
     where.append({'ping_type': 'invite_only', 'invite_list': request.user.id}) 
    where = {'$or': where} 
else: where = {} # Vanity check - show all pings by author 

where['author'] = { '$in' : author_ids } 
where['starts'] = { "$gt":start_dt } 
where['deleted'] = { "$ne": True } 
# print "User View Where = ", where 

feeditems, has_more = ds.Feed.feeditems(request, where) 

feeditems = ds.FeedItem.prepare(feeditems) 
friend_requested = FriendshipInvitation.objects.is_friend_requested(request.user, user) 

if extension: 
    if extension == 'json': 
    return http.HttpResponse(json.dumps(feeditems, indent=2, default=json_handler), 
         mimetype='application/json') 
else: 
    return render_to_response("social/feeditems_list.html", { 
    'feeditems':feeditems, 
    'user':user, 
    'has_more':has_more, 
    'section':'user_feed', 
    'are_friends':are_friends, 
    'friend_requested':friend_requested, 
}, request) 

J'ai besoin essentiellement de passer request.user.id ou user.id à Javascript.

EDIT

En fait, je préférerais passer à javascript comme son propre petit élément tableau JSON, si c'est possible

Peut-être un peu évident, mais que diriez-vous:

<script type="text/javascript"> 
    var userId = {{ user.id|default:null }}; 
</script>
