I am trying to simply update a boolean form value by using an ajax function to update it, because why would I want it to reload, but anyways, I have checked that I am passing the csrf_token, and made sure that's not a problem. I was thinking it was a problem with my urls.py, but I'm not sure exactly what it is.

What can I do to fix this error?

heres my views.py for the ajax form, note: project_plete is a booleanfield in my model

@login_required
def ProjectDetailToDoCForm(request):
    form = ProjectToDoCForm(request.POST or None)
    if form.is_valid() and request.is_ajax():
        args = {}
        args.update(csrf(request))
        ajaxVal = request.POST.get('booleanValue')
        args['doneBool'] = ajaxVal.project_plete
        return HttpResponse(json.dumps(args), content_type="application/json")

javascript

<script type="text/javascript">
    $(document).on("submit", "#project_edit_date", function(e){
        e.preventDefault();
        updateForm();
    });

    function updateForm() {

        function getCookie(name) {
        var cookieValue = null;
        if (document.cookie && document.cookie != '') {
            var cookies = document.cookie.split(';');
            for (var i = 0; i < cookies.length; i++) {
                var cookie = jQuery.trim(cookies[i]);
                if (cookie.substring(0, name.length + 1) == (name + '=')) {
                    cookieValue = decodeURIComponent(cookie.substring(name.length + 1));
                    break;
                }
            }
        }
        return cookieValue;
    }  

        $.ajaxSetup({
            beforeSend: function(xhr, settings) {
                if (!(/^http:.*/.test(settings.url) || /^https:.*/.test(settings.url))) {
                    // Only send the token to relative URLs i.e. locally.
                    xhr.setRequestHeader("X-CSRFToken", getCookie('csrftoken'));
                }
            }
        });

        $.ajax({

            type: "POST",

                console.log("Before Send");
                $.ajaxSettings.beforeSend(xhr, settings);
            },

            success: function(json){
              console.log(json);
              console.log("success");
            },

• 2 You need to post the traceback, from the console or the developer tools. – Daniel Roseman Commented Jun 29, 2015 at 5:48
• The problem is on the server side (like almost always with 500 errors). Look at this: args['doneBool'] = ajaxVal.project_plete where ajaxVal = request.POST.get('booleanValue') is probably a string, i.e. it's highly unlikely that it will have .project_plete attribute. That's what's throwing an exception. – freakish Commented Jun 29, 2015 at 7:45

Just a general tip as you have posted all the code including HTML / JS / Python / urls.py ...

• If you have an error in your JS (Client side error) you will see it in the browser log (console).
• If there is an error in urls.py you will most likely get an HTTP Response 404 Not Found meaning the URL couldn't be resolved.
• If you get a HTTP Response 500 Internal Server Error this most certainly means you have a server error (runtime error in your python code /views.py/.

In general read the most frequent response codes and what they mean here HTTP/1.1: Status Code Definitions
