Django记得我吗'；行不通

我想在浏览器关闭时关闭会话，但若用户选中“记住我”，则会话必须在浏览器关闭后打开，所以我做了此操作，但它不起作用，它总是关闭

my settings.py：

SESSION_EXPIRE_AT_BROWSER_CLOSE = True

我的观点

if request.POST['rememberme']:
        settings.SESSION_EXPIRE_AT_BROWSER_CLOSE = False

视图.py

from django.contrib.auth import views as auth_views

def login_user(request, template_name='registration/login.html', extra_context=None):  
    response = auth_views.login(request, template_name)  
    if request.POST.has_key('remember_me'):    
        request.session.set_expiry(1209600) # 2 weeks

urlpatterns = [
    url(r'^login/$', login_user, name='auth_login'),
]

url.py

from django.contrib.auth import views as auth_views

def login_user(request, template_name='registration/login.html', extra_context=None):  
    response = auth_views.login(request, template_name)  
    if request.POST.has_key('remember_me'):    
        request.session.set_expiry(1209600) # 2 weeks
