In Rails, you can also just add it in your app/controller/application.rb file (so the model is available + # for all controllers). This lets Action Pack know to have the model definition loaded before retrieving the object from the session. # # For removing objects from the session, you can either assign a single key to nil, like @session[:person] = nil, or you can # remove the entire session with reset_session. -- cgit v1.2.3
