WINDOWS SYSTEMS: INSTALLING RUBY ON RAILS

  ------------------------------------------------------------------ 
  NOTE: As of 4/19, Ruby on Rails has been installed under Windows
  on the following stations in the Computer Science Lab (RH 223):

      alarka, alexander, dellwood, franklin, marshall, murphy

  ------------------------------------------------------------------ 

PHASE 1:

  1) Download and install Ruby 1.9.2 (should create folder C:\Ruby192)

  2) Edit the system PATH environment variable to include C:\Ruby192\bin

  3) Download RubyGems 1.7.2 ZIP file and extract the folder it contains

  4) a) Launch a command window (keep this around for later steps)
     b) cd into the extracted Gems folder
     c) Enter the command

        ruby setup.rb

  5) Copy the SQLite DLL file (sqlite3.dll) into C:\Ruby192\bin 

  6) Enter the command

       gem install rails

PHASE 2:

  1) Create and/or move to a convenient folder for storing
     your Rails webapps (each will be a separate subfolder)

  2) To create a new webapp named "hello", enter this sequence
     of commands: 

       rails new hello
       cd hello
       bundle install
       rake db:create
       rails server

  3) If all steps in (2) worked correctly, launch a brower and enter
     the URL

       http://localhost:3000

     Let us hope you now see the Rails "Welcome aboard" page...

     Now shutdown the Rails web server (use ctrl-C) and continue:
 
PHASE 3:

  1) Enter the command
 
        rails generate controller home index

     Now look for folder: hello\app\views\home\index.html.erb,
     edit as desired to customize page
    
  2) Find and remove the file "hello\public\index.html" (if present,
     this will prevent the file above from becoming the welcome page)

  3) Find and edit the configuration file "hello\config\routes.db"
     as follows: locate and uncomment the line

       # root :to => "welcome#index"

     Then change "welcome" to "home", so the final line is

         root :to => "home#index"

  4) Restart the Rails server (rails server), and again use your browser
     to load the URL http://localhost:3000

     Hopefully you now see your hello webapp's home page...
