oki@nil:~$gem li | grep supp
activesupport (2.0.2, 1.4.4)

Jak widać na załaczonym obrazku posiadamy activesupport w dwóch wersjach: 2.0.2 i 1.4.4
Załóżmy, że chcemy użyc starszej wersji.

$ irb
>> gem 'activesupport', '= 1.4.4'
=> true
>> require 'active_support'
=> true

* *Problem1: Jak wygenerować szkielet aplikacji railsowej używajac danej wersji frameworka*

W systeme mamy railsy w wersji 1.2.5 i 2.0.2:

$ gem dep | grep rails
Gem rails-1.2.5
Gem rails-2.0.2

Tworzymy szkielet aplikacji ze wskazaniem na odpowiednią wersję:

oki@nil:~/tmp/test$rails _1.2.5_ app_old
oki@nil:~/tmp/test$rails _2.0.2_ app_new

A następnie sprawdzamy wersje railsów:

oki@nil:~/tmp/test$./app_old/script/console
Loading development environment.
>> Rails::VERSION::STRING
=> "1.2.5"
>> quit
oki@nil:~/tmp/test$./app_new/script/console
Loading development environment (Rails 2.0.2)
>> Rails::VERSION::STRING
=> "2.0.2"

Czekamy na więcej!

* “sd.rb podcast”:http://feeds.feedburner.com/sdrbpodcast – troche o ror, *40* odcinków,
ale aktualnie maja chyba jakieś problemy

* “Ruby Plus”:http://www.rubyplus.org/ – 34 screencasty ruby-railsowe, co kilka dni pojawiają się nowe.

* “peepcode”:http://peepcode.com/ – płatne, kilkanaście bardzo dobrze nagranych, wartościowych screencastów,
tematyka głównie Rails (testowanie, benchmarking, javascipt, rjs, capistrano, git, rspec),
średni czas trwania: 1h.

Na screencastach prezentowane są różne techniki, przepisy, sposoby pisania kodu,
czasami warto poświecić kilka minut na obejrzenie.
W przyszłości oszczędzimy sobie czasu na googlowanie
