I have to code this scenario:
Some user comes to fill a form and while user is at it, session expires;
User tries to submit form, as session has expired it will take him to login
page after which he is rediredted to form page with a prefilled form with
data he filled previously.
my propsed solution: on form submit, check if user session is expired with
an ajax call, if yes, drop a cookie with values of filled form, user comes
back to same form, prefill the form from cookie value.
how far I got: not much; I used ajax call to check session expiry with a
backend call to this function:
def check_valid_session(request):
session_expiry_date = request.session.get_expiry_date()
now = datetime.now()
seconds_left = (session_expiry_date - now).total_seconds()
if seconds_left <= 0:
return JsonResponse({'session_expired': True, 'seconds_left':
seconds_left })
else:
return JsonResponse({'session_expired':False, 'seconds_left':
seconds_left})
in my settings I have:
SESSION_COOKIE_NAME = "sso-sessionid"
SESSION_COOKIE_HTTPONLY = False
SESSION_COOKIE_AGE = 10
SESSION_COOKIE_DOMAIN = '.mydomain.com'
SESSION_COOKIE_SECURE = True
SESSION_EXPIRE_AT_BROWSER_CLOSE = True
but in response, I always get seconds_left as something close to 9.999. and
session_expiry_date keeps increasing itself by 10 seconds each time i hit
submit and call the backend code above. How to get correct session expire
time?
