3.Configure WEBrick (Ruby’s server)<\/p>\n
\r\n$cd test\r\n$ ruby script\/server\r\n\r\n=> Booting WEBrick\r\n=> Rails 2.3.8 application starting on http:\/\/0.0.0.0:3000\r\n=> Call with -d to detach\r\n=> Ctrl-C to shutdown server\r\n[2010-08-02 12:40:40] INFO  WEBrick 1.3.1\r\n[2010-08-02 12:40:40] INFO  ruby 1.8.7 (2010-01-10) [i486-linux]\r\n[2010-08-02 12:40:45] INFO  WEBrick::HTTPServer#start: pid=27681 port=3000\r\n<\/pre>\n
To test your ROR configure paste http:\/\/0.0.0.0:3000<\/a> on your browser.<\/p>\n
4.Creating a Controller, I call it hello.<\/p>\n
\r\n$ ruby script\/generate controller hello\r\n      exists  app\/controllers\/\r\n      exists  app\/helpers\/\r\n      create  app\/views\/hello\r\n      exists  test\/functional\/\r\n      create  test\/unit\/helpers\/\r\n      create  app\/controllers\/hello_controller.rb\r\n      create  test\/functional\/hello_controller_test.rb\r\n      create  app\/helpers\/hello_helper.rb\r\n      create  test\/unit\/helpers\/hello_helper_test.rb\r\n\r\n<\/pre>\n
5.Creating an action, I call it hi.<\/p>\n
In the file app\/controllers\/hello_controller.rb, i have added action “hi”<\/p>\n
\r\n\r\nclass HelloController < ApplicationController\r\n\r\n  def hi\r\n  end\r\n\r\nend\r\n\r\n<\/pre>\n
6.Creating view for the action \"hi\"<\/p>\n
\r\n $ vim app\/views\/hello\/hi.html.erb\r\n\r\n\r\n Hello World!!<\/body>\r\n<\/html>\r\n\r\n<\/pre>\n
Lets test our page again.( Am sure the WEBrick server still running)<\/p>\n
on browser paste this --> http:\/\/0.0.0.0:3000\/hello\/hi<\/a> and you can see your first ROR application in front of you.<\/p>\n","protected":false},"excerpt":{"rendered":"
