Reason given for failure:
CSRF token missing or incorrect.
This error happens even after using csrf_exempt in the views.py page .How to resolve this issue?

Django handles csrf automatically so not need to exempt for your code just add csrf template tag in HTML Template like this...
<form action="" method="post">
{% csrf_token %}
</form>
and remove #csrf_exempt decorator which is on top of add_item
NOTE:- When you send POST request then require to add csrf token in html post form

I want to know all the possible triggers of a 403 Forbidden from CSRF. What causes this error to show up and how can I prevent it, in all of its cases.
Thanks!
There are many possibilities though.
You didn't use one in form
Obvious. Include {% csrf_token %} immediately after your form tag, before all the form fields.
Request needs csrf_token
In some cases involving POST requests, Django will force the use of a csrf_token. There are ways to get around this using custom middleware, but it's too complicated and is prone to cross-site forgery attacks. Instead, just ensure a csrf_token is passed to your view:
#csrf_protect
def your_view(request):
pass
#method_decorator(ensure_csrf_cookie, name='dispatch')
class your_view(View):
pass
I am sending a POST request to my server from an android application, but I am getting this error:
The POST looks like:
http://example/my_page_url/1000
Where the 1000 is an ID.
This is my views method:
def inventory(request, cross_id):
text_file = open("test.txt", "w")
text_file.write('POST Received')
text_file.write(cross_id.__str__())
text_file.close()
return render(request, 'Inventory.html', {})
my template code:
<form action='' method="POST">
<button type="submit" id="btn_save" name="btn_save">Save</button>
{% csrf_token %}
</form>
Actually, I don't really need to call a template, because I want to perform something on the server only. But I am calling the template just to prevent any errors for now.
I have read the other answers for the same problem but all of them have missed the CSRF token in the template or something else in the views method, but I believe the case is different here.
You need to add the X-CSRFToken header to all your POST requests.
You can get the appropriate value for this header from the cookie named csrftoken.
To test this in Postman, you need to enable the Interceptor plugin (top right corner).
Once you have it installed, make a GET request to /admin/login/ (make sure you are logged out from the site in the browser). In the cookies section you should see a cookie named csrftoken, copy its value.
Now, set the request type to POST for the same URL (/admin/login), add a header named X-CSRFToken with the value you copied earlier. Set the username and password fields in the Body section and hit send.
If your POST do not require authentication, you can use the csrftoken from an earlier GET request.
I'm getting this error when I go to http://127.0.0.1:8000/avatar/change/ and click the button 'Upload New Image':
Forbidden (403) CSRF verification failed. Request aborted.
So I went to python27/Lib/site-packages/avatar/templates/avatar/change.html and added
{% csrf_token %} right after <form ... POST...>.
When I refresh the browser and view source I do not see the CSRF token, and the 403 message is still generated.
How do I modify the 'correct' django-avatar template?
Apparently there exist two <form></form> sections in the template. Silly me. I only added the {% csrf_token %} to the first form I found thinking that there was only one form defined under change.html.
All pages are extended from a base template.
There is a form in the base template and the form has the CSRF tag. When submitting the form while on home page, all works fine. However for all other pages (also extended from same base template) the submit fails with the following error:
Forbidden (403)
CSRF verification failed. Request aborted.
Inspecting the page with Firebug, the hidden input field that holds the CSRF token is missing.
You need to do this -
In settings modify - MIDDLEWARE_CLASSES = ('django.middleware.csrf.CsrfViewMiddleware')
Next to any form in your templates, put this - <form method="post" class="login_form" name="frmlogin">{% csrf_token %}
This would solve your problem...
I have a GWT web app working with Django server-side. I recently upgraded Django to 1.2, and am not able to get HTTP posts to work from my GWT app. I am getting this error:
CSRF verification failed. Request
aborted.
Reason given for failure:
CSRF token missing or incorrect.
I have enabled the csrf middlewares ('django.middleware.csrf.CsrfViewMiddleware', 'django.middleware.csrf.CsrfResponseMiddleware') which is working for contrib apps like login, but it seems as though the token is not getting added to posts made through GWT. Any ideas? Thanks in advance.
If you have checked the templates for auth.login you'll notice that a CSRF token is explicitly included inside the <form> tag.
<form method="post" action=".">
{% csrf_token %}
This is expanded into a hidden field when the page is rendered on a GET request. Something like:
<form method="post" action=".">
<div style='display:none'>
<input type='hidden' name='csrfmiddlewaretoken'
value='90064bf0e86edacfdb60595e3e2b8f23' />
</div>
This token is then passed back to the view on POST and validated.
Consequently before you can POST to a CSRF protected view you will have to first get the token from the said view.
Can you verify/ensure that you have the CSRF token handy before making a POST request to the view? Alternately you can disable CSRF protection for the view using the csrf_exempt decorator. This may not be a good idea though.
Update
This is the point of my question: I am not using django templates for my front-end and thus I cannot tag forms with the token. I am using GWT for my front-end, which is rendering the form for the post.
Are you already making a GET request to the Django view before rendering the page? In that case you can get the CSRF token by parsing the contents of the response.
If not you will have to explicitly make a GET request to the view (assuming it supports GET) and parse the response for a CSRF token. For an example see this question.
