[Fixed]-How to write a Django view for a POST request

This is by design. Your POST data must contain csrfmiddlewaretoken value. You can get it from your cookies and then send it with POST requests. Details here. For your specific case, you can do this –

<script>
$(function () {
    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;
    }
    var csrftoken = getCookie('csrftoken');

    $("button")
        .button()
        .click(function (event) {
            var postdata = {
                'value1': 7,
                'value2': 5,
                'csrfmiddlewaretoken': csrftoken
            };
            $.post('', postdata); // POST request to the same view I am now
            window.alert("Hello world!"); // To know it is working
        });
});
</script>
