Question

I’m trying to realize a POST request in Jquery to the Django server. The problem is that I need to pass the CSRF token. So I copy this code in my JS file before the code of the request. But, nothing happens. The Firebug console show me the error 500 (Internal Server Error), and if I change the Post request to a get request, it do the request.

JS File

The copied code

$(document).ajaxSend(function(event, xhr, settings) {
  function getCookie(name) {
    var cookieValue = null;
    if (document.cookie && document.cookie != '') {
        var cookies = document.cookie.split(';');
        for (var i = 0; i < cookies.length; i++) {
            var cookie = jQuery.trim(cookies[i]);
            // Does this cookie string begin with the name we want?
            if (cookie.substring(0, name.length + 1) == (name + '=')) {
                cookieValue = decodeURIComponent(cookie.substring(name.length + 1));
                break;
            }
        }
    }
    return cookieValue;
}
function sameOrigin(url) {
    // url could be relative or scheme relative or absolute
    var host = document.location.host; // host + port
    var protocol = document.location.protocol;
    var sr_origin = '//' + host;
    var origin = protocol + sr_origin;
    // Allow absolute or scheme relative URLs to same origin
    return (url == origin || url.slice(0, origin.length + 1) == origin + '/') ||
        (url == sr_origin || url.slice(0, sr_origin.length + 1) == sr_origin + '/') ||
        // or any other URL that isn't scheme relative or absolute i.e relative.
        !(/^(\/\/|http:|https:).*/.test(url));
}
function safeMethod(method) {
    return (/^(GET|HEAD|OPTIONS|TRACE)$/.test(method));
}

if (!safeMethod(settings.type) && sameOrigin(settings.url)) {
    xhr.setRequestHeader("X-CSRFToken", getCookie('csrftoken'));
}

});

My code

 $(document).ready(function(){
      $.post('/favorites/delete_favorite/' + data_info[0] + '/' + data_info[1], function(data){
           alert(data);
      });

View.py

def delete_favorite(request, content_type=None, object_id=None):

    if request.method == 'POST':
         message = "Hello POST"
    else:        
         message = "Hello"

    return HttpResponse(message)
 });

Solution
I had a error when I sent the url, it missed a slash, so the right solution is:

$(document).ready(function(){
$.post(‘/favorites/delete_favorite/’ + data_info[0] + ‘/’ + data_info[1] + ‘/’, function(data){
alert(data);
});

I don’t remove this post, because it’s posible someone need it.

I think this is what you are looking for, your views.py file looks fine.

$.ajax({
    url:"/favorites/delete_favorite/' + data_info[0] + '/' + data_info[1]",
    type: "POST",
    data: {values:['1','2'], csrfmiddlewaretoken:$("input[name=csrfmiddlewaretoken]").val()},
    success:function(response){
        alert("success: " + response);
    },
    error:function (xhr, textStatus, thrownError){
        alert("xhr status: " + xhr.statusText);
    },

});

Alternatively you can use @csrf_exempt on the view function:

@csrf_exempt
def delete_favorite(request, content_type=None, object_id=None):

    if request.method == 'POST':
        message = "Hello POST"
    else:        
        message = "Hello"

    return HttpResponse(message)
});
