The things I did is

1. zf create project demo1 in command prompt
2. add the lines to application.ini
   • appnamespace = "Application"
   • resources.layout.layoutPath = APPLICATION_PATH "/layouts/scripts"
3. add a layout with header and footer using partial() (They are perfectly worked)

4. create Data.php in models directory and add this simple class

   <?php class Application_Model_Data{   }//Application for appnamespace 
   

5. then I tried to load this class(by creating instance)from index controller index action

   $data = new Application_Model_Data();

6. but when I test it even in this level it gives an error

   Fatal error: Class 'Application_Model_Data' not found in C:\Zend\...\IndexController.php

Question

1. Do I want to add a autoloader to load models in the application( I'm not used modules)
2. if not what was I missed to add

please help I'm stuck in the beginning,Thank you
