Session變量

Question

我打印會話變量中的基本模板如下：

{% if request.session.user_id %} 
Welcome {{ request.session.user_id }}, <a href="/accounts/logout/">Logout</a> 
{% endif %} 

views.py

def loginfun(request): 
    username = request.POST['username'] 
    password = request.POST['password'] 
    errors = [] 
    user = authenticate(username=username, password=password) 
    if user is not None: 
     if user.is_active: 
      login(request, user) 
      request.session['user_id'] = username 
      return render_to_response('home.html', context_instance=RequestContext(request)) 
     else: 
      #errors.append("Account Inactive") 
      return render_to_response('home.html',{'errors':errors}, context_instance=RequestContext(request)) 

settings.py

MIDDLEWARE_CLASSES = (
    'django.middleware.common.CommonMiddleware', 
    'django.contrib.sessions.middleware.SessionMiddleware', 
    'django.middleware.csrf.CsrfViewMiddleware', 
    'django.contrib.auth.middleware.AuthenticationMiddleware', 
    'django.contrib.messages.middleware.MessageMiddleware', 
) 
TEMPLATE_CONTEXT_PROCESSORS = (
    "django.contrib.auth.context_processors.auth", 
    "django.core.context_processors.debug", 
    "django.core.context_processors.i18n", 
    "django.core.context_processors.media", 
    "django.core.context_processors.static", 
    "django.contrib.messages.context_processors.messages", 
    "django.core.context_processors.request", 
) 
INSTALLED_APPS = (
    'django.contrib.auth', 
    'django.contrib.contenttypes', 
    'django.contrib.sessions', 
    'django.contrib.sites', 
    'django.contrib.messages', 
    'django.contrib.staticfiles', 
    'registration' 
) 

Answer 1

django.core.context_processors.request是n ot在TEMPLATE_CONTEXT_PROCESSORS默認情況下，所以你根本沒有{{ request }}變量
