How can i load model in joomla? - module

Question

This is my Controller
// No direct access
defined( '_JEXEC' ) or die( 'Restricted access' );
jimport('joomla.application.component.controller');
/**
* Hello World Component Controller
*
* #package Joomla.Tutorials
* #subpackage Components
*/
class HelloController extends JController
{
/**
* Method to display the view
*
* #access public
*/
function __construct($default = array())
{
parent::__construct($default);
// Register Extra tasks
$this->registerTask( 'detail' , 'display' );
}
function display()
{
switch($this->getTask())
{
case 'detail' :
{
JRequest::setVar( 'view' , 'new');
// Checkout the weblink
$model = $this->getModel('hello');
} break;
}
parent::display();
}
}
this is my view.html.php
class HelloViewNew extends JView
{
function display($tpl = null)
{
global $mainframe;
$db =& JFactory::getDBO();
$model =& $this->getModel('hello');
$items = & $model->getdetail();
$this->assignRef( 'items', $items );
parent::display($tpl);
}
}
and this is my model
defined( '_JEXEC' ) or die( 'Restricted access' );
jimport( 'joomla.application.component.model' );
/**
* Hello Model
*
* #package Joomla.Tutorials
* #subpackage Components
*/
class HelloModelHello extends JModel
{
/**
* Gets the greeting
* #return string The greeting to be displayed to the user
*/
var $_data;
/**
* Returns the query
* #return string The query to be used to retrieve the rows from the database
*/
function _buildQuery()
{
$query = ' SELECT * '
. ' FROM #__hello WHERE published = 1'
;
return $query;
}
/**
* Retrieves the hello data
* #return array Array of objects containing the data from the database
*/
function getData()
{
// Lets load the data if it doesn't already exist
if (empty( $this->_data ))
{
$query = $this->_buildQuery();
$this->_data = $this->_getList( $query );
}
//echo "<pre>"; print_r($this->_data); exit;
return $this->_data;
}
function detail()
{
echo "this is test"; exit;
}
}
My question is how can i fetch that detail function from database its not working for me?

Answer 1

on your model, you've the function : function detail() ,
But you've tried to call the function on view with : $items = & $model->getdetail();
Remember your function is detail() NOT getdetail() . So, call with :
$items = & $model->detail();
That's your only mistake I guess so, good luck

Answer 2

you should use this in contoller
$view = $this->getView();
$view->setModel($this->getModel());
then you can use $this->getModel() in view.
