I am using ExtJs to create a button that do an ajax post to my django application, but the post is blocked by a FORBIDDEN (403) error.

I tryed to pass the CSRF token in as POST data by setting a custom X-CSRFToken header to the value of the CSRF token (https://docs.djangoproject.com/en/1.3/ref/contrib/csrf/#ajax) without success

ExtJS.js

        action =  new Ext.Button({
            text: 'Ajax Test',
            handler: function () {
                Ext.Ajax.request({
                        url: 'test/',
                        method: 'POST',
                        headers: { 'Content-Type': 'application/json'},
                        params: {'test': 'test'},
                        success: function(response, opts) {
                                var obj = Ext.decode(response.responseText);
                                console.dir(obj);
                                },
                        failure: function(response, opts) {
                                console.log('server-side failure');
                                }
                });
            },
         });

view.py

def test(request):
    print "TEST WORKING"
    print dict(request.POST.copy().iteritems())
    return HttpResponse("")

Show us the django view as well..mariodev
Adding the CSRF-token is the correct solution, can you please add it again, then do the request and copy/paste the post and response from your browsers dev tools network tab?krs
habitually the ajax post is working when adding the CSRF-token. I think its not working here because the ajax is initialized through extJSBelow the Radar
@orokusaki: thank you, that post solved my problemBelow the Radar

I put this in my Application launch function:

Ext.require(["Ext.util.Cookies", "Ext.Ajax"], function(){
    // Add csrf token to every ajax request
    var token = Ext.util.Cookies.get('csrftoken');
    if(!token){
        Ext.Error.raise("Missing csrftoken cookie");
    } else {
        Ext.Ajax.defaultHeaders = Ext.apply(Ext.Ajax.defaultHeaders || {}, {
            'X-CSRFToken': token
        });
    }
});
