What is the Django setup for session? - django

Question

I want to save sessions in server side instead of db. right now my project using db to store sessions, as per documentation i removed 'django.contrib.sessions' from installed app but its giving error RuntimeError: Model class django.contrib.sessions.models.Session doesn't declare an explicit app_label and isn't in an application in INSTALLED_APPS. . So, what is the actual setup for session?

Answer 1

Based on the shared settings file, you forgot to specify the SESSION_ENGINE:
Set SESSION_ENGINE to "django.contrib.sessions.backends.cache" for a simple caching session store. Session data will be stored directly in your cache. However, session data may not be persistent: cached data can be evicted if the cache fills up or if the cache server is restarted.
So you should add the following to the settings.py file:
# settings.py
# ...
SESSION_ENGINE = "django.contrib.sessions.backends.cache"
