Django，如何记住用户已登录？

Question

@csrf_protect
def loginn(request):
    c = {}
    c.update(csrf(request))
    return render_to_response("login/login.html",c)

@csrf_protect
def auth_view(request):
    username = request.POST.get('username', '')
    password = request.POST.get('password', '')
    user = authenticate(username=username, password=password)
    if user is not None:
        if user.is_active:
            login(request, user)
            return render_to_response('login/loggedin.html',RequestContext(request))
    else:
        return HttpResponseRedirect('/posts/invalid')

def loggedin(request):
    return render_to_response('login/loggedin.html',
                                 {'full_name' : request.user.username})

def invalid_login(request):
    return render_to_response('login/invalid_login.html')

def logout(request):
    logout(request)
    return render_to_response('login/logout.html')

Here is what I have in my views.py . It's working , checking password , user , etc . But I don't know how to remember that a user has logged in.

I want to show logged/not logged users different Menus. Tried it like that in my templates :

{% block Menu %}
{% if not user.is_authenticated %}
  <li>  <a href="/posts/login">Login</a> </li>
  <li>  <a href="/posts/register/">Register</a></li>
{% endif %}

{% if user.is_authenticated %}
        <li><a href="/posts">Main</a></li>
        <li><a href="#">My profile</a></li>
        <li><a href="/posts/logout">logout</a></li>
    {% endif %}
{% endblock %}

But it works only once and only with render_to_response + RequestContent All other times I have first option. (Login , Register)

So how can I remember that a user has logged in?

ps sorry for my bad english

Adding to Daniel Roseman's comment...

If you want to use render_to_response and have access to the current request objects in your templates, you'll need to pass along RequestContext as well. https://docs.djangoproject.com/en/dev/topics/http/shortcuts/#django.shortcuts.render_to_response

return render_to_response('my_template.html',
    my_data_dictionary,
    context_instance=RequestContext(request))

You may want to take a look at using render instead though as it already includes RequestContext for you. https://docs.djangoproject.com/en/dev/topics/http/shortcuts/#render
