django error: [Errno 32] Broken pipe whan I make an ajax call

Question

I got this error each time taht I make an ajax request, only in this project. The codes involved are listed here:

[JS AJAX CALL]

    var url = '/eden/find_flights/';
    var csrf_token = getCookie('csrftoken');

    $.ajax({
        'url': url,
        'data':  {
            'trip': JSON.stringify(trip),
            'travellers': JSON.stringify(travellers),
            'csrfmiddlewaretoken': csrf_token
        },
        'type': 'POST',
        'dataType': 'json',
        'complete': function(response) {

            $("#result").html(response.responseText); //.animate({'marginTop': "-=700px"}, 'slow', 'swing', function() {});
        },
    });

[views.py]

@csrf_exempt
def find_flights(request):

    flights = {}

    return render_to_response('flight_search_results.html', flights, context_instance=RequestContext(request))

The dict flights will be filled with data, but isn't important now. The problm that I got is that obtain a red line (like error) in firebug, but no error signal (if I use the "Open in a New Tab" option I got a blank page) and in the django console:

You have this code:

var url = '/eden/find_flights/';
var csrf_token = getCookie('csrftoken');

$.ajax({
    'url': url,
    'data':  {
        'trip': JSON.stringify(trip),
        'travellers': JSON.stringify(travellers),
        'csrfmiddlewaretoken': csrf_token
    },
    'type': 'POST',
    'dataType': 'json',
    'complete': function(response) {

        $("#result").html(response.responseText); //.animate({'marginTop': "-=700px"}, 'slow', 'swing', function() {});
    },
});

Does this belong to a .submit() event handler? If it does, have your event call preventDefault. Otherwise your page would be loading and stopping the ajax call.

Why does this only have 1 thumb up? I encountered this issue in React and it did the trick. More info https://reactjs.org/docs/handling-events.html — ratsimihah, Mar 28 '18 at 08:03
