How to disable Django's CSRF validation?

Question

I have commented out csrf processor and middleware lines in settings.py:

122 
123 TEMPLATE_CONTEXT_PROCESSORS = (
124     'django.contrib.auth.context_processors.auth',
125 #    'django.core.context_processors.csrf',
126     'django.core.context_processors.request',
127     'django.core.context_processors.static',
128     'cyathea.processors.static',
129 )
130 
131 MIDDLEWARE_CLASSES = (
132     'django.middleware.common.CommonMiddleware',
133     'django.contrib.sessions.middleware.SessionMiddleware',
134 #    'django.middleware.csrf.CsrfViewMiddleware',
135     'django.contrib.auth.middleware.AuthenticationMiddleware',
136     'django.contrib.messages.middleware.MessageMiddleware',
137     'django.middleware.locale.LocaleMiddleware',
138     # Uncomment the next line for simple clickjacking protection:
139     # 'django.middleware.clickjacking.XFrameOptionsMiddleware',
140 )

But when I use Ajax to send a request, Django still respond 'csrf token is incorrect or missing', and after adding X-CSRFToken to headers, the request would succeed.

What is going on here ?

If you just need some views not to use CSRF, you can use @csrf_exempt:

from django.views.decorators.csrf import csrf_exempt

@csrf_exempt
def my_view(request):
    return HttpResponse('Hello world')

You can find more examples and other scenarios in the Django documentation:

https://docs.djangoproject.com/en/dev/ref/csrf/#edge-cases

Hi, @TheBronx, I really want to know why my solution doesn't work. – WoooHaaaa May 09 '13 at 09:15

sorry @MrROY I don't know why your solution is not working. I just know that `@csrf_exemp` works as I've used it recently without problems. Hope you find the answer. – Salvatorelab May 09 '13 at 09:52

@MrROY, It is a Django thing. Most things do work/doesn't work just because there is a magic setting buried deep down the code base. – idursun Aug 01 '13 at 10:15

A reminder: if you have other decorators in the same view the order is relevant: so place @csrf_exempt first. – Patrick Bassut Dec 13 '13 at 18:53

Hmm- maybe a technically correct answer, but most certainly not what the OP wanted or what I was looking for. – Danny Staple Aug 19 '14 at 12:58
And what do I do if I need *all* views not to use CSRF? – jameshfisher Feb 10 '15 at 15:02

In setting.py in MIDDLEWARE you can simply remove/comment this line:

'django.middleware.csrf.CsrfViewMiddleware',

this works for me on Django 2.1 using curl as an http client. – clay Mar 19 '19 at 15:35

@xtrinch Make sure you fully quit/re-launch the server process. I don't think the auto-relaod picks up the change – Basic Apr 07 '19 at 22:23

To disable CSRF for class-based views, the following worked for me.

I'm using Django 1.10 and Python 3.5.2

from django.utils.decorators import method_decorator
from django.views.decorators.csrf import csrf_exempt

@method_decorator(csrf_exempt, name='dispatch')
class TestView(View):
    def post(self, request, *args, **kwargs):
        return HttpResponse('Hello world')

The problem here is that SessionAuthentication performs its own CSRF validation. That is why you get the CSRF missing error even when the CSRF Middleware is commented. You could add @csrf_exempt to every view, but if you want to disable CSRF and have session authentication for the whole app, you can add an extra middleware like this -

class DisableCSRFMiddleware(object):

    def __init__(self, get_response):
        self.get_response = get_response

    def __call__(self, request):
        setattr(request, '_dont_enforce_csrf_checks', True)
        response = self.get_response(request)
        return response

I created this class in myapp/middle.py Then import this middleware in Middleware in settings.py

MIDDLEWARE = [
    'django.middleware.common.CommonMiddleware',
    'django.middleware.security.SecurityMiddleware',
    'django.contrib.sessions.middleware.SessionMiddleware',
    'django.middleware.common.CommonMiddleware',
    #'django.middleware.csrf.CsrfViewMiddleware',
    'myapp.middle.DisableCSRFMiddleware',
    'django.contrib.auth.middleware.AuthenticationMiddleware',
    'django.contrib.messages.middleware.MessageMiddleware',
    'django.middleware.clickjacking.XFrameOptionsMiddleware',

]

That works with DRF on django 1.11

Thank you for actually giving an answer to the question instead of just posting a solution. — ThaJay, Dec 14 '18 at 15:44
I followed your solution but I get this error: ```'str' object has no attribute 'get'```. My django version is 3.2.6 though. @Madhuri — Maisum Abbas, Aug 17 '21 at 10:06

For Django 2:

from django.utils.deprecation import MiddlewareMixin


class DisableCSRF(MiddlewareMixin):
    def process_request(self, request):
        setattr(request, '_dont_enforce_csrf_checks', True)

That middleware must be added to settings.MIDDLEWARE when appropriate (in your test settings for example).

Note: the setting isn't not called MIDDLEWARE_CLASSES anymore.

The answer might be inappropriate, but I hope it helps you

class DisableCSRFOnDebug(object):
    def process_request(self, request):
        if settings.DEBUG:
            setattr(request, '_dont_enforce_csrf_checks', True)

Having middleware like this helps to debug requests and to check csrf in production servers.

Hmm. Tried this in Django 1.9.1. Removed the @csrf_exempt decorator from the method and added the code above. Got a 403 because the cookie was not set. – Craig S. Anderson Feb 05 '16 at 01:58

If you want disable it in Global, you can write a custom middleware, like this

from django.utils.deprecation import MiddlewareMixin

class DisableCsrfCheck(MiddlewareMixin):

    def process_request(self, req):
        attr = '_dont_enforce_csrf_checks'
        if not getattr(req, attr, False):
            setattr(req, attr, True)

then add this class youappname.middlewarefilename.DisableCsrfCheck to MIDDLEWARE_CLASSES lists, before django.middleware.csrf.CsrfViewMiddleware

Before using this solution, please read this link from documentation

I solved this problem with the following two steps:

Add this class to an utils.py file:

from django.utils.deprecation import MiddlewareMixin

from <your-project-name> import settings
class DisableCSRF(MiddlewareMixin):
   def process_request(self, request):
      if settings.DEBUG:
         setattr(request, '_dont_enforce_csrf_checks', True)

And in the settings.py file, add above middleware to the MIDDLEWARE list:

...
MIDDLEWARE = [
    ...
    'django.middleware.csrf.CsrfViewMiddleware',
    ...
    '<path-of-utils.py>.utils.DisableCSRF',
]
...

CSRF can be enforced at the view level, which can't be disabled globally.

In some cases this is a pain, but um, "it's for security". Gotta retain those AAA ratings.
