Rails - Oct 2007 - How to save an object with its associations into session

Hi,

How do I save an object with its children into the session? By default
AR cleans the children when I  put the object there.

And if someone knows any docs about that please show the link.

Thks,

Bruno Reis

What do you mean it cleans by default ?

Start
session[:user] = User.find(1)

then you can do this
session[:user].id

or that?
session[:user].contacts.length

In general, it''s a *bad* idea to put a full AR object in the session.
It
mostly works, but it can get you in trouble. The accepted best practice 
is to store the id in the session, then fetch the record from the 
database when you need it. That way you avoid the nasty synchronization 
issues etc.

session[:user_id] = user.id

then later...

user = User.find(session[:user.id])
