How can I get the sessid from the current session object?
For instance, I log in the system, and want to know which sessid I’m
using.
I’m storing the session using active_record. Later on, I want to restore
a session finding it using the sessid.
Thanks in advance.

session.session_id (regardless of the session store.)

Hmm: this is already done automatically based on cookie or query
parameter. Do you need to find an arbitrary session?
Also, those using the Active Record session store may set the
underlying session model:
CGI::Session::ActiveRecordStore.session_class = MySessionClass
and access the session’s model instance:
session.model
session.model.is_a?(MySessionClass)
(take a look at the default CGI::Session::ActiveRecordStore::Session
in actionpack/lib/action_controller/session/active_record_store.rb)
So you may
Subclass the default with some additional behavior.
class MyApp::Session < CGI::Session::ActiveRecordStore::Session
belongs_to :user
# …
end
CGI::Session::ActiveRecordStore.session_class = MyApp::Session
before
def session_user() @session_user ||= User.find(session[:user_id]) end
def login(user) … session[:user_id] = user.id … end
after
session.user
def login(user) … session.user = user … end
Best,

Where can I change this code?
I want something like this…
In my app.
session[:user_id] = “15”
session[:group_id] = “18”
This will generate a session. I will store it in a database, and later
on I want to restore it. Without cookies and so forth.
Later, I want something like restoring a session.
@id = ID OF THE PREVIOUS CREATED SESSION.
@session = Session.find(:first, :conditions=> [“sessid = ?”, @id])
@session[:user_id] #returns the user id of the session
I know that the session data attribute is marshaled. How can I restore
it?
Thanks in advance.

automatic. Just use session directly and forget about it.
When you do session[:user_id] = foo, the session is created if not
present, updated with :user_id => foo. When the action is complete,
the session is serialized and stored for you. On next page load,
session is reconstituted according to the value of cookie OR query
parameter _session_id.
Hum, the problem is that I’m not loading the session in a page. I will
load it in another app. I’m integrating rails with a old system…
Because of that, I need to retrieve the values previously stored in the
session. To use in the app.
Because I can store it in the database, I thought that will be easy to
restore the values. Is it possible?
Thanks in advance.

Session data is serialized to the database using Marshal.dump so
direct access from a non-Ruby app is not too useful. There’s
probably a simpler way to exchange data between your apps…

You don’t need any of these mechanics - session load/save is
automatic. Just use session directly and forget about it.
When you do session[:user_id] = foo, the session is created if not
