Django: CSRF token missing or incorrect

Django: CSRF token missing or incorrect

The "CSRF token missing or incorrect" error in Django occurs when Django's CSRF protection mechanism detects that a Cross-Site Request Forgery (CSRF) token is either missing or doesn't match what's expected. CSRF tokens are used to protect against malicious websites or attackers making unauthorized requests on behalf of authenticated users.

To resolve this issue, you can take the following steps:

  1. Ensure {% csrf_token %} is in Your HTML Form:

    • Make sure that your HTML form contains the {% csrf_token %} template tag. This tag generates the CSRF token and should be placed within the <form> element.
    <form method="POST" action="/your-form-action/">
    {% csrf_token %}
    <!-- Other form fields go here -->
    <input type="submit" value="Submit">
</form>

  2. Use POST Requests for Form Submission:

    • Ensure that your form submission uses the HTTP POST method, as Django's CSRF protection is designed to work with POST requests.

  3. Include {% csrf_token %} in AJAX Requests:

    • If you are making AJAX requests that modify data on your site, ensure that you include the CSRF token in the request headers or data. You can obtain the CSRF token from the {% csrf_token %} template tag and pass it in the AJAX request.

  4. Check for Middleware Order:

    • If you have custom middleware that modifies or reorders request data, ensure that it does not interfere with Django's CSRF middleware. Django's CSRF middleware should typically be placed high in the middleware stack.

  5. Verify Your Application Logic:

    • Double-check your application logic, especially if you are using custom forms, views, or authentication mechanisms, to ensure that you are handling CSRF tokens correctly.

  6. Clear Browser Cookies:

    • Sometimes, browser cookies may become corrupted. Clear your browser's cookies and try again.

  7. Check for CSRF Middleware Settings:

    • Ensure that the django.middleware.csrf.CsrfViewMiddleware middleware is included in your MIDDLEWARE setting in your Django project's settings file (usually settings.py).

  8. Verify Your Session:

    • Check if your session is properly configured. Ensure that the django.contrib.sessions.middleware.SessionMiddleware middleware is also included in your MIDDLEWARE setting.
