ajax handling in cbv how?

Question

Django

def form_invalid(self, form):
        if self.request.is_ajax():
            data = {
                'code': 0,
                'message': form.errors

            }
            return JsonResponse(data)
        else:
            response = super(AjaxableResponseMixin, self).form_invalid(form)
            return response

    def form_valid(self, form):
        form.instance.subject = "Заявка перезвонить № " + str(random.randint(1, 999999))
        form.instance.type = "1"

        if form.instance.phone == '':
            if self.request.is_ajax():
                data = {
                    'code': 0,
                    'message': 'Проверьте информацию',
                }
                return JsonResponse(data)
        else:
            response = super(AjaxableResponseMixin, self).form_valid(form)
            if self.request.is_ajax():
                data = {
                    'code': 1,
                    'message': 'Успешно отправлено',
                }
                return JsonResponse(data)
            else:
                return response

But this is not entirely correct, but how to track each error and return it in the json response in order to process it and highlight the field through js. Who makes the bikes?

Answer 1

def ajax_errors(form):
    return {f: e.get_json_data(False) for f, e in
            form.errors.items()}
...
data = ajax_errors(form)
