Rails - Mar 2005 - Redirecting to the previous view

Greetings,

I''m trying to implement a simple authentication system. The
''login''
action of the ''users'' controller looks like this:

  def login
    @session["user"] =
User.authenticate(@params["username"],
@params["password"])
    if current_user.guest?
      @session["login_message"]="Invalid Login"
    end
    redirect_to(:action => "index")
  end

The ''redirect_to'' call naturally redirects to the
''index'' action of the
''users'' controller, but I would like for it to redirect to the
previous
view, whatever view that happens to be. What would be the best mechanism 
for achieving this?

Peter.

I think I got this out of heirarki, you should look in the "open source 
projects" link at rubyonrails.org community section for other useful 
examples.

     @session[:return_to] = @request.request_uri # cross-controller 
compatible
    redirect_to_url @session[:return_to]
