Send request to View Django, without receiving any response - django

Question

I ask the user a question on my website and if the answer is yes, I will send two data to view Django using a JavaScript file and using Ajax. I want to get this data in View Django and not send any HttpResponse to the user.
If we do not send a response in the view, it will give an error. How should I do this?
When the condition if request.is_ajax ():
Runs, I get the following error:
ValueError: The view tourist.views.planing did not return an HttpResponse object. It returned None instead.
Thanks
def planing(request):
if request.is_ajax():
# Get user location from user location.js file:
latitude = request.POST.get('latitude', None)
longitude = request.POST.get('longitude', None)
# To save data
request.session['latitude'] = latitude
request.session['longitude'] = longitude
elif request.method == "GET":
return render(request, "tourist/planing.html")
elif request.method == "POST":
# To retrive data:
latitude = request.session.get('latitude')
longitude = request.session.get('longitude')
if latitude is not None :
latitude = float(latitude)
longitude = float(longitude)
.
.
.
return render(request, "tourist/map.html")

You can return an empty JSON. Like so:
from django.http import JsonResponse
if request.is_ajax():
# Get user location from user location.js file:
latitude = request.POST.get('latitude', None)
longitude = request.POST.get('longitude', None)
# To save data
request.session['latitude'] = latitude
request.session['longitude'] = longitude
return JsonResponse({})
This will ensure there is a response back to the AJAX request.
