Session data works in local server, not in server - Django

Question

I have a Django app which uses cookie session to pass data from one to another template/functions.

The problem that I face is that while setting the cookie with either file based, DB based it worked in local perfectly, but while I try set the same session in Digital Ocean development server, it failed for some unknown reason.

Here are file which transaction with session

settings.py

Attempt 1:

SESSION_ENGINE = "django.contrib.sessions.backends.signed_cookies"
SESSION_COOKIE_NAME = "user_session"
SESSION_COOKIE_HTTPONLY = True
SESSION_SAVE_EVERY_REQUEST = True
SESSION_EXPIRE_AT_BROWSER_CLOSE = True

Attempt 2:

SESSION_ENGINE = 'django.contrib.sessions.backends.file'
SESSION_FILE_PATH = os.path.join(BASE_DIR, "session")

views.py

def pre_login(request):
    request.session['pre_login'] = data
    ....

def index(request):
    user_data = request.session['pre_login']
    ....

While checking the cookie session in browser, it creates a sessionid for Localhost. But when checking session for the same code, there is nothing for my development server.

Answer 1

You're setting the value in the request. When you try to get it in another view you're out of scope.
