why post doesnt do anything

Question

everyone! I'm writing a simple django application. There is script on one of the pages, which works on the button click and uses ajax post. The problem is: post method doesn't cause execution of server code and just executes function on error every time.

script:

<script type="text/javascript">
    (function($) {
        $(document).ready(function(){
            {% for obj in cl.result_list %}
                $('#done_{{ obj.pk }}').click(function() {
                    if ($(this).html().indexOf("icon-yes") != -1) {
                        $action = "no";
                    }
                    else {
                        $action = "yes";
                    }
                    $.ajax({
                                type: "POST",
                                url: "/on_hold_done/done/" + $action + "/{{ obj.pk }}/",
                                success: function(response) {
                                    alert("success")
                                },
                                error: function(response) {
                                    alert("error")
                                }
                            })
                });
            {% endfor %}
        });})(django.jQuery);
</script>

in urls.py:

(r"^on_hold_done/(on_hold|done)/(yes|no)/(\d*)/$", "todo.views.on_hold_done")

in views.py:

@staff_member_required
def on_hold_done(request, mode, action, pk):
    """simple code here"""
    return HttpResponse('')

The $action variable looks like it could cause a problem since the $ has special function in jQuery. — Björn, Mar 29 '11 at 13:26
@Bjorn: Naming a variable `$action` is not a problem. JavaScript variables can contain the `$` character. The `$` variable is just a reference to `jQuery`. — gen_Eric, Mar 29 '11 at 13:33
@blazkovicz: Looks like the issue is resolved, with the answer below (or its discussion) providing part or all of the solution - could you accept OR provide a new answer that you think better answers the question? — Tao, Oct 25 '11 at 12:57

If you're using Django 1.3, note that all AJAX requests are now subject to cross-site request forgery protection, so you'll need to add in some extra JS to automatically include the CSRF token in your ajax submission. See the docs here

Thanks, I've just got to the same point in problem solving. The cause of problem is indeed in absence of using CSRF. And there also was problem in url resolving. – blazkovicz Mar 29 '11 at 17:40
Could anyone explain me what should I right in order to pass CSRF? I couldn't find any code examples. Solution from djangoproject doesn't work for me, because in response there is a piece of html, not a document or httpresponce. – blazkovicz Mar 29 '11 at 17:59
Add the JS mentioned here http://docs.djangoproject.com/en/dev/ref/contrib/csrf/#ajax - that will automaticaly insert the CSRF token as an additional header in your AJAX request – Steve Jalim Mar 30 '11 at 10:55
I've tried this code, it didn't help, but solution from http://stackoverflow.com/questions/5100539/django-csrf-check-failing-with-an-ajax-post-request did. – blazkovicz Mar 31 '11 at 06:59
