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