I thought I understood how to grab the session id but in the following code I am getting null for the session id: @foo = Foo.new(:session\_id =\> session[:session\_id], :test\_id =\> @test.id) ---

The session isn’t an AR instance so you’re getting Ruby’s Object#id method which isn’t what you want. I believe that session is an instance of CGI::Session so you probably really want session.session\_id instead. ---

Everything else aside… why on earth are you trying to capture the session id? Rails is handling the user sessions for you, all you need to do is work with the session object in your controllers and views. I honestly can’t think of a single reason why I would want to grab a session id and then put it into one of my own tables… -Brian ---

I’m not sure what the de-facto-standard is here… but I typically treat the session object as if it were a magical hash. session[:session\_id]… just like you’d do with params, cookies, and flash. @foo = Foo.new( :session\_id =\> session[:session\_id], :test\_id =\> @test.id ) Cheers, Robby Robby R.
