To Create the Controller and the View

The next step in creating and deploying the hello application is to create an application controller and a default application view.

• The controller handles requests, dispatches them to other parts of the application as necessary, and determines which view to render.

• The view is the file that generates the output to the browser. In Rails, views are typically written with ErB, a templating mechanism.

1. Change to the directory in which you created the hello application in To Create the hello Application.

   In this example:

   cd /apps/jruby-apps/hello

2. Create a controller and default view for your application:

   jruby script/generate controller home index

   You should see a controller file called home_controller.rb in the hello/app/controllers directory, and a view file called index.html.erb in the hello/app/views directory.

3. Proceed with the instructions in To Pass Data From the Controller to the View.
