Why is Django admin login giving me 403 CSRF error?

问题

I am running Django 1.2.2 and I get the following error when I try to log in to the Django admin:

Forbidden (403) CSRF verification failed. Request aborted.

Reason given for failure:

No CSRF or session cookie.

** I have made NO customization to the barebones admin and when I inspect the source there is a CSRF token in the form in what I believe is the correct place.

When I look at the actual request that is being sent there is a csrf token being sent but Django still says CSRF verification failed.

Can anyone point me in the right direction? Why is this happening?

回答1:

1) Do you have 'django.middleware.csrf.CsrfViewMiddleware' in your settings.MIDDLEWARE_CLASSES ?

2) Are you sure you've always been on 1.2.2? That only came out last night...

I've had the same problem on Django 1.2.1 FINAL. Since I knew that Django on our production site would never be updated from 1.0 (for various reasons), I found a workaround which I implemented into my development version of settings.py, leaving the production settings.py untouched.

Create a middleware.py file in your application directory with the following code:

class disableCSRF:
    def process_request(self, request):
        setattr(request, '_dont_enforce_csrf_checks', True)
        return None

Then in your development version of settings.py, insert this into MIDDLEWARE_CLASSES:

'your_app_name.middleware.disableCSRF',

Perhaps not the safest solution, but our Django site is strictly internal, so there is a minimum risk for any type of malicious actions. This solution is simple and doesn't involve changes to templates/views, and it worked instantly (unlike other I've tried).

Hopefully someone in a similar situation to mine will find this useful.

Credit goes to John McCollum, on whose site I've found this.

According to the docs, not only do you need the csrf hidden form field, but also the csrftoken cookie. The error message you provided also suggests a missing cookie.

I would look in your browser's cookies to ensure the csrftoken cookie is present.
