django CSRF validation

Question

I can't get around the CSRF token validation 403 error. Here's what I have:

view:

from django.template import RequestContext
def add(request, name):
#logic
return render_to_response("category/add.html", {"form": form}, 
    context_instance = RequestContext(request))    

template:

<form action="/category/add/" method="post">
    {% csrf_token %}
    New Category: <input type="text" name="name" id="categoryname" />
    <input type="submit" value="Hinzufuegen" />
</form>

settings:

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',
)

Answer 1

Seems like you need to add

'django.middleware.csrf.CsrfViewMiddleware',
'django.middleware.csrf.CsrfResponseMiddleware',

to your MIDDLEWARE_CLASSES. Seems that it is not validating CSRF token, just generating... helped me in my case...
