    shovell-debug-01 not starting up

    Hi all,

    I'm on chapter 11 of the book, Simply Rails 2, and have followed the instruction to start the server using the shovell-debug-01 folder and files.

    However, when I attempted to do that, I got the following error:

    Code:
    Missing the Rails 2.0.2 gem. Please `gem install -v=2.0.2 rails`, update your RAILS_GEM_VERSION setting in config/environment.rb for the Rails version you do have installed, or comment out RAILS_GEM_VERSION to use the latest version installed.
    As I am running the 2.3.5 version of rails (the latest that I got from gems), I commented out the RAILS_GEM_VERSION line.

    Upon trying to start the server, I then got the following error and the server doesn't start.

    Code:
    /Library/Ruby/Gems/1.8/gems/rails-2.3.5/lib/initializer.rb:602:in `send': undefined method `cache_template_extensions=' for ActionView::Base:Class (NoMethodError)
    	from /Library/Ruby/Gems/1.8/gems/rails-2.3.5/lib/initializer.rb:602:in `initialize_framework_settings'
    	from /Library/Ruby/Gems/1.8/gems/rails-2.3.5/lib/initializer.rb:601:in `each'
    	from /Library/Ruby/Gems/1.8/gems/rails-2.3.5/lib/initializer.rb:601:in `initialize_framework_settings'
    	from /Library/Ruby/Gems/1.8/gems/rails-2.3.5/lib/initializer.rb:598:in `each'
    	from /Library/Ruby/Gems/1.8/gems/rails-2.3.5/lib/initializer.rb:598:in `initialize_framework_settings'
    	from /Library/Ruby/Gems/1.8/gems/rails-2.3.5/lib/initializer.rb:155:in `process'
    	from /Library/Ruby/Gems/1.8/gems/rails-2.3.5/lib/initializer.rb:113:in `send'
    	from /Library/Ruby/Gems/1.8/gems/rails-2.3.5/lib/initializer.rb:113:in `run'
    	 ... 6 levels...
    	from /Library/Ruby/Gems/1.8/gems/rails-2.3.5/lib/commands/server.rb:84
    	from /Library/Ruby/Site/1.8/rubygems/custom_require.rb:31:in `gem_original_require'
    	from /Library/Ruby/Site/1.8/rubygems/custom_require.rb:31:in `require'
    	from script/server:3
    Could somebody tell me what is going wrong, and how I am able to fix it? I don't actually wish to downgrade my version of rails to the 2.0.2... I'm stuck at this stage of the book until I can get this to work.

    edit: yes, I do get the same error when I am attempting to run shovell-debug-02

    Can you show me the code in your config/environment.rb file?

    Urmm. It's mostly commented out stuff. But here we go. The original one that I got from the code archive:

    Code:
    # Be sure to restart your server when you modify this file
    
    # Uncomment below to force Rails into production mode when
    # you don't control web/app server and can't set it the proper way
    # ENV['RAILS_ENV'] ||= 'production'
    
    # Specifies gem version of Rails to use when vendor/rails is not present
    #RAILS_GEM_VERSION = '2.0.2' unless defined? RAILS_GEM_VERSION
    
    # Bootstrap the Rails environment, frameworks, and default configuration
    require File.join(File.dirname(__FILE__), 'boot')
    
    Rails::Initializer.run do |config|
      # Settings in config/environments/* take precedence over those specified here.
      # Application configuration should go into files in config/initializers
      # -- all .rb files in that directory are automatically loaded.
      # See Rails::Configuration for more options.
    
      # Skip frameworks you're not going to use (only works if using vendor/rails).
      # To use Rails without a database, you must remove the Active Record framework
      # config.frameworks -= [ :active_record, :active_resource, :action_mailer ]
    
      # Only load the plugins named here, in the order given. By default, all plugins 
      # in vendor/plugins are loaded in alphabetical order.
      # :all can be used as a placeholder for all plugins not explicitly named
      # config.plugins = [ :exception_notification, :ssl_requirement, :all ]
    
      # Add additional load paths for your own custom dirs
      # config.load_paths += %W( #{RAILS_ROOT}/extras )
    
      # Force all environments to use the same logger level
      # (by default production uses :info, the others :debug)
      # config.log_level = :debug
    
      # Your secret key for verifying cookie session data integrity.
      # If you change this key, all old sessions will become invalid!
      # Make sure the secret is at least 30 characters and all random, 
      # no regular words or you'll be exposed to dictionary attacks.
      config.action_controller.session = {
        :session_key => '_shovell_session',
        :secret      => '6bfbb8f2bed66a842a3f9eda009ccdf2875fc569e856b09be2ea3470cd006901668ff833bcae0d1317c290d48881a5c84ec47fa37ab456d7a34c6cc1d1667a75'
      }
    
      # Use the database for sessions instead of the cookie-based default,
      # which shouldn't be used to store highly confidential information
      # (create the session table with 'rake db:sessions:create')
      # config.action_controller.session_store = :active_record_store
    
      # Use SQL instead of Active Record's schema dumper when creating the test database.
      # This is necessary if your schema can't be completely dumped by the schema dumper,
      # like if you have constraints or database-specific column types
      # config.active_record.schema_format = :sql
    
      # Activate observers that should always be running
      # config.active_record.observers = :cacher, :garbage_collector
    
      # Make Active Record use UTC-base instead of local time
      # config.active_record.default_timezone = :utc
    end

    Instead of commenting out the RAILS_GEM_VERSION line, change the 2.0.2 to 2.3.5
