python - Django - how to redirect to index page upon logout? -

i'm trying implement simple page redirect index page if user authentication fails.

imagine have 2 paths:

www.xyz.com/app/ www.xyz.com/app/user 

the first renders index page, , second authorized user landing page on successful login.

in views.py file, have

def index(request):   return render(request, "app/index.html")  def userlogin(request):   loginuser = authenticate(username = request.post["username"], password = request.post["password"])    if loginuser not none:     if not loginuser.is_active:       loginuser.is_active = true       loginuser.save()        login(request, loginuser)       return httpresponse(reverse(user))         else:       return httpresponse(simplejson.dumps({"login" : "failed"}))  def userlogout(request):   logout(request)   return httpresponseredirect(reverse(index)) 

and urls.py

urlpatterns = patterns("",   url(r'^$', views.index, name = "index"),   url(r'^user/$', views.user, name = "user"),   url(r'^registernewuser/$', views.registernewuser),   url(r'^userlogin/$', views.userlogin),   url(r'^user/userlogout/$', views.userlogout), ) 

the logout function accessed via ajax post request, , in logs, see

 [11/jul/2013 09:08:00] "post /app/user/userlogout/ http/1.1" 302 0  [11/jul/2013 09:08:00] "get /app/ http/1.1" 200 5039 

but index page not loading. however, if refresh page, index page loads, due conditional call request.user.is_authenticated() triggers same httpresponseredirect call , parameters on fail.

if login fail mean in else case return render(request, "app/index.html") instead of return httpresponse(simplejson.dumps({"login" : "failed"}))  **updated userlogin**  def userlogin(request):     loginuser = authenticate(username = request.post["username"],     password = request.post["password"])  if loginuser not none: if not loginuser.is_active:   loginuser.is_active = true   loginuser.save()    login(request, loginuser)   return httpresponse(reverse(user))     else:   return render(request, "app/index.html")
