Django-如何在注销后重定向到索引页面？

Question

I'm trying to implement a simple page redirect to the index page if user authentication fails.

Imagine that I have two paths:

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

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

In my views.py file, I 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 is 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 is accessed via an Ajax POST request, and in the logs, I 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 the index page is not loading. However, if I refresh the page, the index page loads, due a conditional call to request.user.is_authenticated() which triggers the same HttpResponseRedirect call and parameters on fail.

Answer 1

If login fail i 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 is 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")
