Notes

rake routes shows the routes that are set-up for a given application

in routes.rb map.resources :model sets up the standard RESTful routes for a model.

in views

<% @models.each do |model| -%>
  <%= link_to "Link text", model_path(model) %>
<% end -%>

will set up links to the model object

in views

  <%= debug @object %>

Changing the default IP address and Port

In rails3 if you want to change the default IP address and port that a rails app runs (without external scripts or changing the rails source) then you need to alter the script/rails file.

The following was derived from this post and this change to dradis and just sets the default IP address for the app. to be 127.0.0.1 and the default port to be 3000.

require 'rubygems'
require 'rails/commands/server'
require 'rack'
require 'webrick'
 
module Rails
  class Server < ::Rack::Server
    def default_options
      super.merge({
        :Port => 3003,
        :Host => "127.0.0.1",
        :environment => (ENV['RAILS_ENV'] || "development").dup,
        :daemonize => false,
        :debugger => false,
        :pid => File.expand_path("tmp/pids/server.pid"),
        :config => File.expand_path("config.ru")
      })
    end
  end
end
