Question

我在基本模板中打印会话变量，如下所示：

{% 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默认不在TEMPLATE_CONTEXT_PROCESSORS中，因此您根本没有{{ request }}变量

会话变量未显示
