I am working on a Django project. All went well till I created an Ajax request to send values from the html page to the backend (views.py).
When I send the data using Ajax, I am able to view the values being passed to views.py, and it even reaches the render_to_response method and displays my page, but throws the broken pipe error in the terminal. I don't see any kind of disruption to the program, but I wanted to know if there is a way to prevent this error from occurring. I checked the other responses. But no luck so far.
When I try to hit submit again on the refreshed page, I get this message:
The page that you're looking for used information that you entered. Returning to that page might cause any action you took to be repeated. Do you want to continue? [Submit] [Cancel]`
Here is the dump:

Update:
Here is the code that I am sending:
$( 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);
}
});
});
});
And here is my 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")
I am still facing the same issue. Can someone help me with this?
Edit on 5/28/2014:
I just figured out the reason for a Broken Pipe. It was because I was not sending back the response from Python and was just expecting the page to refresh automatically. I am a newbie to all of this, and took me a while to figure out why this happened.
