Django 1.6 messages not showing up - django

Question

I followed the docs to import necessary stuff into my settings, views and template. However, no messaging is showing up.
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',
# Uncomment the next line for simple clickjacking protection:
'django.middleware.clickjacking.XFrameOptionsMiddleware',
)
INSTALLED_APPS = (
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.sites',
'django.contrib.messages',
Example view:
from django.contrib import messages
def add_news(request):
if request.method == 'POST':
form = NewsForm(request.POST)
if form.is_valid():
form.save()
messages.info(request, "News was added")
return HttpResponseRedirect('/')
if request.method == 'GET':
form = NewsForm()
args = {}
args.update(csrf(request))
args['form'] = form
return render_to_response('news/add_news.html', args)
In base.html I have:
{% block messages %}
{% if messages %}
<ul class="messages">
{% for message in messages %}
<li{% if message.tags %} class="{{ message.tags }}"{% endif %}>{{ message }}</li>
{% endfor %}
</ul>
{% endif %}
{% endblock messages %}
How should I debug this?

The messaging framework makes use of a context_processor to deliver the messages to the template. To make sure the variables from your context_processors are actually added to the context you render your template with, you have to use a RequestContext in your view.
If you’re using the context processor, your template should be rendered with a RequestContext. Otherwise, ensure messages is available to the template context.
You are using the render_to_response method which doesn't do this by default. You either need to specify the use of a RequestContext or use the render function instead which does this by default
return render_to_response('news/add_news.html',
args,
context_instance=RequestContext(request))
