You are not sending the server generated csrf_token for the POST to verify the validity of the data. Hence the error.

As a part of the data part of the request, you need to send the token

csrfmiddlewaretoken: '{{ csrf_token }}' 

Something like this

var data = {
    url: item.find("#id_url").val(),
    title: item.find("#id_title").val(),
    tags: item.find("#id_tags").val(),
    csrfmiddlewaretoken: '{{ csrf_token }}' 
};

Or you could simply do:

var data = $('form').serialize()

if you want to send the whole form as a dictionary

var csrftoken = Cookies.get('csrftoken');

xhr.setRequestHeader("X-CSRFToken", csrftoken);

enter link description here

This is what I use. Not sure if it's applicable in your situation though.

// sending a csrftoken with every ajax request
function csrfSafeMethod(method) {
    // these HTTP methods do not require CSRF protection
    return (/^(GET|HEAD|OPTIONS|TRACE)$/.test(method));
}
$.ajaxSetup({
    crossDomain: false, // obviates need for sameOrigin test
    beforeSend: function(xhr, settings) {
        if (!csrfSafeMethod(settings.type)) {
            xhr.setRequestHeader("X-CSRFToken", $.cookie('csrftoken'));
        }
    }
});

var CSRF_TOKEN = '{{ csrf_token }}';  

Past this is js file
