Hi everyone,

I want to ask if it's possible to save object reference in database for
later use?

Regards,
Jamal

No, not directly. How should that work?

You either need an OR mapper (for example ActiveRecord) or you store
complete object graphs serialized (via Marshal in a BLOB or YAML in a
CLOB).

Well, technically it *is* possible to save object references - see
weakref.rb for an implementation.

But this is almost certainly not what the OP wants (since those object
references won't survive garbage collection, or application restart)

Hey, normally *I* am supposed to be the nitpick! What's the point in
storing something that you cannot reasonably retrieve? This is only
useful for a WOM. *gg*

Exactly!

Kind regards
