I'm trying to work out how to get a user's session id. I can't use: cookies['_session_id'] since it won't be in the user's cookie cache at the time of the first request. Any help would be appreciated.

I'm a bit of a newbie, but I'll try to help... I have a model containing class User < ActiveRecord::Base and I set the session ID in a controller with def login session[:user_id] = nil if request.post? user = User.authenticate(params[:name], params[:password]) if user session[:user_id] = user.id ... and I retrieve it in a view as e.g. User id: <%= session[:user_id] %> and all of this is copied from Thomas et al. Agile Web Develoopment with Rails (version 2), a book that I recommend highly.

Thanks Dan, I'm talking about the actual number that rails assigns to users using a cookie called '_session_id' > and all of this is copied from Thomas et al. Agile Web Develoopment > with Rails (version 2), a book that I recommend highly.

I would rather put all the information in the session, so I get receive what I need like this session[:user][:id] session[:user][:username] etc. this way I don't need to connect to the database everytime I need other information about the uesr

From your example above, I suspect you may not be able to treat session[:user] like a full bown ActiveRecord::Base derived class. You won't be able to use the new CookieStore for the sessions if you store too much data in them (which is by the way faster than ActiveRecord or Pstore and doesn't need an external process like the Memcache store). I use this when I need to access the current user and only store its id in session[:user_id]. def current_user # Cache the User instance (probably used multiple times in a request) return @cached_user if @cached_user session[:user_id] ? (@cached_user = User.find(:first, :conditions => [ 'id = ?', session[:user_id]])) : nil end Avoid hitting several time the database for the same data in a single request, but don't get in the way if the data has been modified behind your back. If you really need to avoid database access, you can use acts_as_cached or CachedModel for your users without the drawbacks of explicitely caching them in the session... Lionel

Wish someone would answer your actual question... I've scoured the docs and google and can't find anything about getting the session id. That's something I used to do fairly often in Java, but I haven't actually needed it in rails yet. Why do you need the session id? b

Well, I would reply to my own last email, but google can be hella slow accepting mail... Anyway, you're gonna laugh: session.session_id Sometimes it's better to just try something in the code than to search for it. :-) b
