[Django]-Django CSRF Cookie Not Set

from django.http import HttpResponse
from django.views.decorators.csrf import csrf_exempt

@csrf_exempt 
def your_view(request):
    if request.method == "POST":
        # do something
    return HttpResponse("Your response")

If you’re using the HTML5 Fetch API to make POST requests as a logged in user and getting Forbidden (CSRF cookie not set.), it could be because by default fetch does not include session cookies, resulting in Django thinking you’re a different user than the one who loaded the page.

You can include the session token by passing the option credentials: 'include' to fetch:

var csrftoken = getCookie('csrftoken');
var headers = new Headers();
headers.append('X-CSRFToken', csrftoken);
fetch('/api/upload', {
    method: 'POST',
    body: payload,
    headers: headers,
    credentials: 'include'
})

From This
You can solve it by adding the ensure_csrf_cookie decorator to your view

from django.views.decorators.csrf import ensure_csrf_cookie
@ensure_csrf_cookie
def yourView(request):
 #...

if this method doesn’t work. you will try to comment csrf in middleware. and test again.

If you’re using DRF, check if your urlpatterns are correct, maybe you forgot .as_view():

So that how mine code looked like:

urlpatterns += path('resource', ResourceView) 

And that’s how it should like:

urlpatterns += path('resource', ResourceView.as_view())

I came across a similar situation while working with DRF, the solution was appending .as_view() method to the view in urls.py.

try to check if your have installed in the settings.py

 MIDDLEWARE_CLASSES = (
'django.middleware.common.CommonMiddleware',
'django.contrib.sessions.middleware.SessionMiddleware',
'django.middleware.csrf.CsrfViewMiddleware',)

In the template the data are formatted with the csrf_token:

<form>{% csrf_token %}
</form>

This problem arose again recently due to a bug in Python itself.

http://bugs.python.org/issue22931

https://code.djangoproject.com/ticket/24280

Among the versions affected were 2.7.8 and 2.7.9.
The cookie was not read correctly if one of the values contained a [ character.

Updating Python (2.7.10) fixes the problem.

This also occurs when you don’t set the form action.
For me, it was showing this error when the code was:

<form class="navbar-form form-inline my-2 my-lg-0" role="search" method="post">

When I corrected my code into this:

<form class="navbar-form form-inline my-2 my-lg-0" action="{% url 'someurl' %}" role="search" method="post">

my error disappeared.

If you are not using {% csrf_token %} tag in the template you are rendering. Django won’t set the csrftoken cookie.

To force django to set the csrftoken cookie, add ensure_csrf_cookie decorator in you view.

from django.views.decorators.csrf import ensure_csrf_cookie

@ensure_csrf_cookie
def myview(request):

In my particular case, the problem is that I was using the Django rest_framework and forgot to add the following decorators to my function:

from rest_framework.decorators import api_view, renderer_classes

@api_view(('POST',))
@renderer_classes((JSONRenderer,))
def handle_web_request(request):
    ...

I get this error and change this:

<form method="post">

to this:

<form method="POST">

and it’s solved !
Just upper case post make the problem !
I have not any issue with this on 127.0.0.1, but when i use 192.168.x.x address this broke my forms.

In my case, setting CSRF_COOKIE_SECURE to False wasn’t enough but setting it to Null/ not specifying the parameter worked.

In my case, the problem was that the path to the static files in nginx was incorrectly specified.

sudo tail -F /var/log/nginx/error.log

Check if there are errors in file paths.

Problem seems that you are not handling GET requests appropriately or directly posting the data without first getting the form.

When you first access the page, client will send GET request, in that case you should send html with appropriate form.

Later, user fills up the form and sends POST request with form data.

Your view should be:

def deposit(request,account_num):
   if request.method == 'POST':
      form_=AccountForm(request.POST or None, instance=account)
      if form.is_valid(): 
          #handle form data
          return HttpResponseRedirect("/history/" + account_num + "/")
      else:
         #handle when form not valid
    else:
       #handle when request is GET (or not POST)
       form_=AccountForm(instance=account)

    return render_to_response('history.html',
                          {'account_form': form},
                          context_instance=RequestContext(request))

Check that chrome’s cookies are set with default option for websites. Allow local data to be set (recommended).

Method 1:

from django.shortcuts import render_to_response
return render_to_response(
    'history.html',
    RequestContext(request, {
        'account_form': form,
    })

Method 2:

from django.shortcuts import render
return render(request, 'history.html', {
    'account_form': form,
})

Because render_to_response method may case some problem of response cookies.

I have just met once, the solution is to empty the cookies.
And may be changed while debugging SECRET_KEY related.

Clearing my browser’s cache fixed this issue for me. I had been switching between local development environments to do the django-blog-zinnia tutorial after working on another project when it happened. At first, I thought changing the order of INSTALLED_APPS to match the tutorial had caused it, but I set these back and was unable to correct it until clearing the cache.

I was using Django 1.10 before.So I was facing this problem.
Now I downgraded it to Django 1.9 and it is working fine.

Make sure your django session backend is configured properly in settings.py. Then try this,

class CustomMiddleware(object):
  def process_request(self,request:HttpRequest):
      get_token(request)

Add this middleware in settings.py under MIDDLEWARE_CLASSES or MIDDLEWARE depending on the django version

get_token – Returns the CSRF token required for a POST form. The token is an alphanumeric value. A new token is created if one is not already set.

I had the same error, in my case adding method_decorator helps:

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

method_decorator(csrf_protect)
def post(self, request):
    ...

Just want to point out my case here as someone might cross the same fields.

Forbidden (CSRF cookie not set.): /main/staff/products/validation/create
HTTP POST /main/staff/products/validation/create 403 [0.01, 127.0.0.1:55940]

This thing was driving me insane… So, by commenting CSRF middleware

 MIDDLEWARE_CLASSES = (
'django.middleware.common.CommonMiddleware',
'django.contrib.sessions.middleware.SessionMiddleware',
 # 'django.middleware.csrf.CsrfViewMiddleware',
)

it gave me

POST Method not allowed.

That was my hint, after all.
I was sure Post method was present.
Turns out my url_patterns was leading to another view by a regex bug.

So no matter what I was doing in my view, @csrf_exempt @ensure_crsf_cookie, looking for .as_view()… I was looking at the wrong view.

So, if nothing works, make sure your are actually being sent to the right view.

You can get this error while deploing Django application with NO SSL.
If this is the case then putting an SSL reverse-proxy or SSL-configured Ingress in front of backend will solve the problem.

I just tried this solution it work for me.
You have to set CSRF_USE_SESSIONS to True, basically the csrf token will be stored in a session
https://docs.djangoproject.com/en/4.1/ref/settings/#std-setting-CSRF_USE_SESSIONS

In your view are you using the csrf decorator??

from django.views.decorators.csrf import csrf_protect

@csrf_protect
def view(request, params):
....
