Rails on Windows April 2009

(Much content based on http://www.netbeans.org/kb/docs/ruby/rapid-ruby-weblog.html)

• Install Ruby 1.8.6 from the one-click installer.
• Install MySQL 5.0.27, as a Windows Service, with developer Tools.
• Install NetBeans 6.5.1 with just the Ruby package.
• gem update –system
• gem install mysql
  1. It installed mysql-2.7.3-mswin32.  Note: Only MySQL 5.0.27 works with 2.7.3 of the gem.  That is the version it was linked with when it was compiled.  If you mismatch the versions, you’ll get “rake aborted! undefined method `each' for #<Mysql:…”
  2. It gave an error installing the doc, but the rest appears OK.

Let’s add Clearance authentication:

In config/environment.rb:

config.gem "thoughtbot-clearance", 
  :lib     => 'clearance', 
  :source  => 'http://gems.github.com', 
  :version => '>= 0.5.3'

In config/environments/test.rb:

config.gem 'thoughtbot-shoulda',
  :lib     => 'shoulda',
  :source  => "http://gems.github.com", 
  :version => '2.10.0'
config.gem 'thoughtbot-factory_girl',
  :lib     => 'factory_girl',
  :source  => "http://gems.github.com", 
  :version => '>= 1.2.0'

Then:

rake gems:install
rake gems:unpack 
rake gems:install RAILS_ENV=test
rake gems:unpack  RAILS_ENV=test

ruby script/generate clearance

Define a HOST constant in your environments files. In config/environments/test.rb and config/environments/development.rb it can be:

HOST = "localhost"

In production.rb it must be the actual host your application is deployed to. The constant is used by mailers to generate URLs in emails.

In config/environment.rb (outside the ‘do’):

DO_NOT_REPLY = donotreply@dialectic.us

Migrate Database / to current version

Add this to posts_controller.rb

  before_filter :authenticate, :except => [:index, :show]

Confirm that you can view posts but not create them without logging in

To logout enter http://localhost:3000/sessions/destroy

If you put “map.logout    '/logout',    :controller => 'sessions',  :action => 'destroy' ” into routes.rb, you can logout with http://localhost:3000/logout

These are some handy routes:

map.register  '/register',  :controller => 'users',     :action => 'new'
map.login     '/login',     :controller => 'sessions',  :action => 'new'
map.logout    '/logout',    :controller => 'sessions',  :action => 'destroy'
