Getting started with Ruby on Rails

Here is a very simple tutorial to get started : http://www.digitalmediaminute.com/article/1816/top-ruby-on-rails-tutorials. First 2 links on that page are a good start:

Rolling with Ruby on Rails : http://oreilly.com/pub/a/ruby/archive/rails.html?page=1

Rolling with Ruby on Rails, Part 2 : http://oreilly.com/ruby/archive/rails2.html

Points below are some issues I faced and how I resolved them. I installed Ruby with the one-click installer for Windows : http://rubyforge.org/frs/?group_id=167. This also installs gem which can be thought of as a package manager.

C:\Projects>gem install rails –remote
Install required dependency actionpack? [Yn]  Y
Install required dependency rack? [Yn]  Y
Install required dependency fcgi? [Yn]  Y
Building native extensions.  This could take a while…
ERROR:  While executing gem … (Gem::Installer::ExtensionBuildError)
    ERROR: Failed to build gem native extension.

ruby extconf.rb install rails –remote
checking for fcgiapp.h… no
checking for fastcgi/fcgiapp.h… no
*** extconf.rb failed ***
Could not create Makefile due to some reason, probably lack of
necessary libraries and/or headers.  Check the mkmf.log file for more
details.  You may need configuration options.

Provided configuration options:
        –with-opt-dir
        –without-opt-dir
        –with-opt-include
        –without-opt-include=${opt-dir}/include
        –with-opt-lib
        –without-opt-lib=${opt-dir}/lib
        –with-make-prog
        –srcdir=.
        –curdir
        –ruby=c:/ruby/bin/ruby
        –with-fcgi-dir
        –without-fcgi-dir
        –with-fcgi-include
        –without-fcgi-include=${fcgi-dir}/include
        –with-fcgi-lib
        –without-fcgi-lib=${fcgi-dir}/lib

Gem files will remain installed in c:/ruby/lib/ruby/gems/1.8/gems/fcgi-0.8.7 for
inspection.
Results logged to c:/ruby/lib/ruby/gems/1.8/gems/fcgi-0.8.7/ext/fcgi/gem_make.out

The problem was that the one click installer for the Ruby on Windows installs version 0.9.4 of gems. An update via

gem update –system

brings it up to 1.3.4 which then allows successful install.

C:\Documents and Settings\VSanzgiri>gem update –system

Bug fixes:

* Fix use of prerelease gems.
* Gem.bin_path no longer escapes path with spaces. Bug #25935 and #26458.

Deprecation Notices:

* Bulk index update is no longer supported (the code currently remains, but not
  the tests)
* Gem::manage_gems was removed in 1.3.3.
* Time::today was removed in 1.3.3.

RubyGems installed the following executables:
        c:/ruby/bin/gem

RubyGems system software updated

 

Then you may install rails:-

C:\Documents and Settings\VSanzgiri>gem install rails –remote
Successfully installed rack-1.0.0
Successfully installed actionpack-2.3.4
Successfully installed actionmailer-2.3.4
Successfully installed activeresource-2.3.4
Successfully installed rails-2.3.4

The tutorial assumes you have installed sqlite3 adapter. If not then you will have to modify /cookbook/config/database.yml to point to mysql installation.
