>Ruby on Rails: How to load session objects into console

>

This took a little bit of poking around, so I decided to post it here.

Basically I was tracking down a bug, which resulted in a corrupt object (cart) in the web session. So I thought, it would be nice to play with this object in the console to see what’s up… But how do I get it in there?

There may be a more elegant way to do this but here is how I got it to load:

1. Look in tmp/sessions and find the most recent file (ls -alrt on UNIX). Let’s say the file is called ‘tmp/sessions/ruby_sess.8eb9614a7e4e1e3b’
2. Open console and type:

   >> session = Marshal.load(File.open('tmp/sessions/ruby_sess.8eb9614a7e4e1e3b'))
   => {"hash"=>{:cart=...
   >> cart = session["hash"][:cart]
   ....
   

   In this case I was trying to access a cart object in the session, which was placed in the session with:session[:cart] = Cart.new

That’s it!
