Use previously requested data in another request

[kayhan]

Hi

I first send a request to Django and save its data with a session.

I will send another request to Django later. Here I want to use the data of the previous request.

But my code does not work properly. And the value "None" appears in the output.

Does anyone know what I should do?

Thankful

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) print("latitude, longitude = ", latitude,longitude) # To save data request.session['latitude'] = latitude request.session['longitude'] = longitude # To retrive data: latitude = request.session.get('latitude') longitude = request.session.get('longitude') print("latitude, longitude = ", latitude,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') print("latitude, longitude = ", latitude,longitude) Output: latitude, longitude = 34.801595 48.499574 latitude, longitude = 34.801595 48.499574 latitude, longitude = None None

We can save that in any django model in ajax() request if possible.

You can check if you have modified `SESSION_COOKIE_AGE` (https://docs.djangoproject.com/en/dev/ref/settings/#std:setting-SESSION_COOKIE_AGE)

if it is too less that might be the reason.

Thanks but I did not change the settings.
And to test, SESSION_COOKIE_AGE = 5 * 60,
  I added to the settings but there is still the same problem.
