Django报错

[11/Sep/2018 20:57:07] "POST /applyforprivileges/ HTTP/1.1" 500 12918ERROR: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/views/decorators/csrf.py", line 58, in wrapped_view    return view_func(*args, **kwargs)  File "/data/archer_product/sql/query.py", line 377, in applyforprivileges    query_auditors = request.POST['query_auditors']  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_exemptdef 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                    },
