报错的原因：

变量中的 query_auditor 表单数据没有获取到。

@csrf_exempt
def applyforprivileges(request):
    title = request.POST['title']
    cluster_name = request.POST['cluster_name']
    priv_type = request.POST['priv_type']
    db_name = request.POST['db_name']
    valid_date = request.POST['valid_date']
    limit_num = request.POST['limit_num']
    query_auditors = request.POST('query_auditor')

解决方法：

将表单数据通过AJAX方式正确推送到视图

                //提交请求
                $.ajax({
                    type: "post",
                    url: "/applyforprivileges/",
                    dataType: "json",
                    data: {
                        title: title,
                        cluster_name: cluster_name,
                        priv_type: priv_type,
                        db_list: db_list,
                        db_name: db_name,
                        table_list: table_list,
                        valid_date: valid_date,
                        limit_num: limit_num,
                        apply_remark: apply_remark,
                        query_auditor: query_auditor
                    },
