ajax post request to view - ajax

Question

I am trying to make a simple ajax request to a view but keep having a not Found error for the given url:
Not Found: /myapp/start_session/1/scan_ports/
"POST /myapp/start_session/1/scan_ports/ HTTP/1.1" 404 5711
js
$(document).ready(function() {
$.ajax({
method: 'POST',
url: 'scan_ports/',
data: {'csrfmiddlewaretoken': '{{csrf_token}}'},
success: function (data) {
alert("OK!");
},
error: function (data) {
alert("NOT OK!");
}
});
});
url
url(r'^scan_ports/$',views.ScanPorts,name='scan_ports'),
view
#login_required
def ScanPorts(request):
user = request.user
if request.method == 'POST':
currentSetting = models.UserSetting.objects.filter(isCurrent=True)
if currentSetting.serialPort:
print("GOT IT!")
return HttpResponse('')
Is the ajax request not set properly?

Answer 1

Assuming you are in the "myapp" app, replace:
method: 'POST',
url: 'scan_ports/',
for this:
method: 'POST',
url: '/myapp/scan_ports/',

Answer 2

First check your urls, the url on which you posted is incorrect hence 404 not found error.
Try to define your url in your JS as: {% url 'scan_ports' %} which will search your urls with the name your provided in urls.py
In addition, this may not be a good approach to submit a form via ajax.
Your JS should be something like this:
$('.form-class-name').on('submit', function (e) {
e.preventDefault();
console.log("ajax is called");
$.ajax({
type: $(this).attr('method'),
url: "/url-name/",
data: $(this).serialize(),
dataType: 'json',
success: function(data) {
alert("success");
},
error: function(data) {
alert("Failure");
}
})
}
e.preventDefault() prevents the natural/default action, and prevents from submitting the form twice.
.serialize(), serializes the form data in a json format.
append a "/" before and after your action url.
Your view must return a dictionary as ajax deals with JSON format.
Edit your view like this:
if request.method == "POST":
currentSetting = models.UserSetting.objects.filter(isCurrent=True)
if currentSetting.serialPort:
print("GOT IT!")
a = {'data':'success'}
return HttpResponse(json.dumps(a))
This will return a dictionary required by the ajax.
