AJAX POST not actually sending POST data with Django
I want to submit a form to my Django back end using an AJAX post. I have multiple forms on the page but only want the one the user submits to be the one that sends. The form is held in a modal: <div class="modal-body"> <div class='content-section'> <form method="POST" id="form{{ prod.id }}" class="showform" value="{{ prod.id }}" > <input type="hidden" value="{{ prod.id }}" name="prodid"> {% csrf_token %} <fieldset class='form-group'> {{ form|crispy}} </fieldset> </form> </div> </div> <div class="modal-footer"> <div class='form-group'> <button class="btn btn-outline-info submit-form" value={{prod.id}} form="form{{ prod.id }}" >Save To Profile</button> </div> <button type="button" class="btn btn-default" data-dismiss="modal">Close</button> </div> When the submit button is pressed, it triggers the following AJAX : $(document).on('click', '.submit-form', function () { var thisButton = $(this)[0] var prodID = $(this).val(); var form = $("form" + prodID); $.ajax({ type: 'post', headers:{ "X-CSRFToken": '{{ csrf_token }}' }, url: '/ajax/validate_showadd/', dataType: 'json', contentType: 'json', data: { 'form': form.serialize(), "prodID":prodID, }, success: function (data) { console.log("sent") }, error: function(data) { console.log("error") } }); return false; }); However, within Django whenever I try access any of these values it just returns 'None' and the QueryDict for the POST request is empty.
