Re: for loop + transaction.on_commit + celery = Unexpected Behaviour

[Martin Pätzold]

This is an older topic, but for everyone who found this discusion and had 
the same issue: The problem is most likely using "lambda" inside a 
for-loop. If you switch out "lambda" for "functools.partial" it should work 
as expected.

Re: Use previously requested data in another request

[kayhan]

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.

Re: Use previously requested data in another request

[Lalit Suthar]

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.

Re: How to get a variable from an ajax request and use it in another application in Django?

[kayhan]

Hi
Sorry, as you said I used the session.
But my problem has not been solved yet.

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.
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 retrieve 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 retrieve data: latitude = request.session.get('latitude')
longitude = request.session.get('longitude') print("latitude, longitude = ",

latitude, longitude = 34.801595 48.499574 latitude, longitude = None None
