Workshop 5-part 2

To Do - Part2


1. Create a new application called scenery in the same projects directory to demonstrate the use of an active view.

> rails scenery
> cd scenery



2. Create a controller called Demo in scenery\app\controllers
scenery> ruby script/generate controller Demo


3. Add an action to demo_controller.rb as the method called rubycobe


4. Add a view template - scenery\app\views\demo\rubycode.rhtml
We will edit this view in later steps but you may like to add your own test HTML code to the view at this stage.


5. Save and restart the Web server and navigate to http://localhost:3000/demo/rubycode


6. Use the Time.now example to pass data from an action to a view.



7. Modify and save the rubycode action with a value for the time instance variable in the DemoController class in app\controllers\demo_controller.rb




8. Then modify and save the corresponding view template in \app\views\demo\rubycode.rhtml by adding a call by reference to the action’s instance variable:




9. Restart the Web server and navigate the browser to http://localhost:3000/demo/rubycode

Data has been passed from the action to the view as it is done with SQL requests. The instance variables of a Ruby class are available to view templates by referencing the action’s instance variables by name in the view .rhtml template.
