How much can be stored in sessions? Can it hold model records and their associations?
Jose
Hi Jose,
In theory, the amount you can store in a session is limited only by the size of a "text" field in the underlying database (usually gigabytes) if you are using ActiveRecord session storage; or the maximum size of a file on your filesystem if you are using file storage of sessions.
And yes: you can store ActiveRecord objects in a session.
But in practice, I've had Rails throw "stack level too deep" errors when I've had data in sessions that's very deeply linked (i.e. objects that contain links to other objects, that contain links to others etc. etc.). I've learnt from bitter experience that sometimes it's better to store object IDs in the session and to fetch the objects back again on the next request.
But as long as you don't overkill it, you might find it works fine for you.
