Django报错

[11/Sep/2018 20:57:07] "POST /applyforprivileges/ HTTP/1.1" 500 12918
    ERROR:default:Traceback (most recent call last):
      File "/data/venv4archer/lib/python3.6/site-packages/django/utils/datastructures.py", line 320, in __getitem__
        list_ = super(MultiValueDict, self).__getitem__(key)
    KeyError: 'query_auditors'
    During handling of the above exception, another exception occurred:
    Traceback (most recent call last):
      File "/data/venv4archer/lib/python3.6/site-packages/django/core/handlers/base.py", line 132, in get_response
        response = wrapped_callback(request, *callback_args, **callback_kwargs)

      File "/data/venv4archer/lib/python3.6/site-packages/django/utils/datastructures.py", line 322, in __getitem__
        raise MultiValueDictKeyError(repr(key))
    django.utils.datastructures.MultiValueDictKeyError: "'query_auditors'"

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
                        },
