I am currently getting a permission denied when I try to use POST with ajax.
I believe this is because of CSRF as my post works fine when I use the
@csrf_exempt
decorator on my view. I would appreciate it if someone could tell me what I might be doing wrong here.I tried this SO post however that does not help.I then attempted to follow the python documentation here regarding this issue however I am still getting the permission denied error.
Here is my code
In the view I am doing something like this
@csrf_protect
def showMgmt(request):
cntxt = {}
.....
.....
response = render(request, 'management.html', cntxt)
return response
@csrf_protect
def AjaxDestination(request):
return response("...")
Now initially first the showMgmt
function display the management.html
which contains the following ajax request. This ajax request attempts to do a POST event on the other function AjaxDestination
page:management.html
<script>
// using jQuery
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');
function csrfSafeMethod(method) {
// these HTTP methods do not require CSRF protection
return (/^(GET|HEAD|OPTIONS|TRACE)$/.test(method));
}
function sameOrigin(url) {
// test that a given url is a same-origin 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));
}
$.ajaxSetup({
beforeSend: function(xhr, settings) {
if (!csrfSafeMethod(settings.type) && sameOrigin(settings.url)) {
// Send the token to same-origin, relative URLs only.
// Send the token only if the method warrants CSRF protection
// Using the CSRFToken value acquired earlier
xhr.setRequestHeader("X-CSRFToken", csrftoken);
}
}
});
function jsonResult_ajaxCall(url,data,callback){
$.ajax({
type: 'POST',
url: url,
dataType: "text",
data : data,
success: function(response) {
var jresult = JSON.parse(response);
callback(jresult);
},
error: function(xhr) {
callback(false);
}
});
}
The function jsonResult_ajaxCall
basically calls the ajax function.
Any suggestion on why I am still getting permission denied would be helpful. Thanks
