错误: [Errno 32] 管道破裂

Question

我正在做一个Django项目。一切都很顺利，直到我创建了一个Ajax请求，用来把值从HTML页面发送到后台（views.py）。

当我通过Ajax发送数据时，我能看到这些值被传递到views.py，并且它甚至能到达render_to_response方法，显示我的页面，但在终端却出现了“broken pipe”的错误。我没有看到程序有什么中断，但我想知道有没有办法防止这个错误出现。我查看了其他的回答，但到现在为止还没有找到解决办法。

当我在刷新后的页面上再次点击提交时，我收到了这个消息：

您正在查看的页面使用了您输入的信息。返回该页面可能会导致您采取的任何操作被重复。您想继续吗？[提交] [取消]

这是我的错误信息：

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。有人能帮我解决这个吗？

2014年5月28日更新：我刚刚找到了“broken pipe”的原因。是因为我没有从Python发送回响应，只是期待页面自动刷新。我对这一切还是个新手，花了一些时间才弄明白为什么会发生这种情况。
