错误:[Errno 32]管道破裂

我正在研究一个Django项目.一切顺利,直到我创建了一个Ajax请求,将值从html页面发送到后端(views.py).

当我使用Ajax发送数据时,我能够查看传递给views.py的值,它甚至可以到达render_to_response方法并显示我的页面,但会在终端中抛出损坏的管道错误.我没有看到任何类型的程序中断,但我想知道是否有办法防止此错误发生.我检查了其他回复.但到目前为止没有运气.

当我尝试在刷新的页面上再次点击提交时,我收到以下消息:

您要查找的页面使用了您输入的信息.返回该页面可能会导致您重复执行任何操作.你想继续吗？[提交] [取消]`

这是转储:

更新: 这是我发送的代码:

    $( document ).ready(function() {
$.csrftoken();
$("#submitdata").click(function(){
    //values = [tmode, fmode, t_cool, t_heat, hold];
    values = {
    "tmode": tmode,
    "fmode": fmode,
    "t_cool": t_cool,
    "t_heat": t_heat,
    "hold": hold
    };
    var jsonText = JSON.stringify(values);
    $.ajax({
        url: "/submitdata/",
        type: 'POST',
        data: jsonText,
        dataType: 'json',
        success:function(data){
            console.log(data.success);
        },
        complete:function(){
            console.log('complete');
        },
        error:function (xhr, textStatus, thrownError){
            console.log(thrownError);
            console.log(obj);
        }
    });       
});
});

这是我的views.py:

@login_required
def submitvalues(request):
    #context = RequestContext(request)
    if request.POST:
        jsonvalues = json.loads(request.raw_post_data)
        print jsonvalues
        return HttpResponse(json.dumps(dict(status='updated')), mimetype="application/json")

我仍然面临同样的问题.有人可以帮我弄这个吗？

编辑2014年5月28日:我刚刚弄清楚了管道破裂的原因.这是因为我没有发回Python的响应,只是期望页面自动刷新.我是所有这一切的新手,并花了一些时间来弄清楚为什么会这样.

您尚未发布任何代码,但这可能是因为您在按钮提交时触发了Ajax请求但未阻止默认操作.所以发出了Ajax请求,但是当它返回数据时,浏览器已经请求了下一页,所以没有什么可以接收它.
