Installation: 

 aptitude install sudo ruby rdoc ruby-dev make libmysqlclient-dev gettext unzip git-core subversion nginx monit...
 cd tmp; wget http://rubyforge.org/frs/download.php/57643/rubygems-1.3.4.tgz; tar xvfz rubygems-1.3.4.tgz; cd rubygems-1.3.4; ruby setup.rb
 gem install rake rails

In dem (ersten) RoR-Projekt sollten in der „environment.rb“ (Rails::Initializer.run) folgende Zeilen enthalten sein: 

 [[...]]
 config.gem 'rtex'
 config.gem 'sqlite3-ruby', :lib => 'sqlite3'
 config.gem 'mysql'
 config.gem 'mongrel'
 config.gem 'authlogic'
 config.gem 'grosser-i18n_data', :lib => 'i18n_data', :source => 'http://gems.github.com'
 config.gem 'grosser-fast_gettext', :lib => 'fast_gettext', :source => 'http://gems.github.com/'
 config.gem 'gettext', :lib => false
 config.gem 'haml'
 config.gem 'mislav-will_paginate', :lib => 'will_paginate', :source => 'http://gems.github.com'
 [[...]]

… welche man dann ganz einfach installieren kann… und wenn man schonmal dabei ist, auch gleich ein paar nützliche Plugins dazu: 

 cd <RoR_PROJEKT_PFAD>
 rake gems:install
 haml --rails .
 ruby script/plugin install 'rspec', :git => 'git://github.com/dchelimsky/rspec.git'
 ruby script/plugin install 'rspec-rails', :git => 'git://github.com/dchelimsky/rspec-rails.git'
 ruby script/plugin install 'exception_notifier', :git => 'git://github.com/rails/exception_notification.git'
 ruby script/plugin install 'asset_packager', :git => 'git://github.com/sbecker/asset_packager.git'
 ruby script/plugin install 'gettext_i18n_rails', :git => 'git://github.com/grosser/gettext_i18n_rails.git'
 ruby script/plugin install 'timer', :svn => 'http://activewarehouse.rubyforge.org/svn/timer/trunk/'

Nun noch nen bissl konfigurieren und es kann mit groooßen Schritten losgehen!

Für eigene Zwecke hatte ich mal ein RoR-Template erstellt, welches ich ja eigentlich mal zu einem ganz einfachen Template umscripten und hier einfügen könnte!? ;-)

User und Gruppe „rails“ anlegen!

So, das ist erstmal der Anfang = Durcheinander…

sortiert wird später! :-P

Interessante RoR-Projekte:

danach conf/environment.rb folgendes hinzufuegen: 

 config.gem "rubyist-aasm", :lib => "aasm", :source => "http://gems.github.com"

danach ein einfaches 

 script/generate authenticated user sessions --aasm

danach ein einfaches 

 script/generate roles Role User
