Problem viewing my hello world app

Rails
1

Hi,

I’ve created a hello world app that i want to view but i get
CGI::Session::CookieStore::TamperedWithCookie error in the browser when
i run it. I copied everything in my browswer below and I’ve also listed
the steps I took in creating the hello world.

My steps:

  1. rails hello
  2. generated a controller: ./script/generate controller salutation
  3. created an action by modifying salutation_controller.rb file in
    app/controller dir.
    class SalutationController < ApplicationController
    def hello
    @message = ‘hello world!’
    end
    end
  4. created an rhtml template in app/view/salutation/ called hello.rhtml
    using code below:

<%= @message %>

5. typed http://localhost:3000/salutation/hello in firefox 3.0.4 browser.

I’m using ubunut 8.10 and rails 2.2.2 and i had webrick running with
server/script command.

CGI::Session::CookieStore::TamperedWithCookie in
SalutationController#hello

CGI::Session::CookieStore::TamperedWithCookie

That’s usually an indication that the cookie associated with the
localhost session (in your case it will have a name like
“_hello_session”) is different from the one your current session is
trying to create.

Use the firefox->preferences->privacy->show cookies to remove the
localhost cookie and reload the page.
