Question

hello I just want to ask whether we can call a view method to a model? I know that we can call it on our controller in zend framework. Like if I want to call the url method of view on my controller I can call it like this

$this->view->url(array(),'');

and on the view we just can call it by

$this->url(array(),'');

But When I tried to call the same method on my model by

$this->view->url(array(),'');

it generates an error of call to undefined method url.
Now I want to ask whether it is possible to call view method to a model? If yes then how? What Am I doing wrong.
Thanks

If you want to use the URL helper, why not inject / lazy load it in your model, eg

class Application_Model_MyModel
{
    /**
     * @var Zend_Controller_Action_Helper_Url
     */
    private $urlHelper;

    public function setUrlHelper(Zend_Controller_Action_Helper_Url $helper)
    {
        $this->urlHelper = $helper;
        return $this;
    }

    /**
     * Lazy load URL action helper
     *
     * @return Zend_Controller_Action_Helper_Url
     */
    protected function getUrlHelper()
    {
        if (null === $this->urlHelper) {
            $this->setUrlHelper(
                Zend_Controller_Action_HelperBroker::getStaticHelper('url'));
        }
        return $this->urlHelper;
    }

    public function someMethod()
    {
        $url = $this->getUrlHelper()->url(array(), null);
    }

This way, you can either pass the helper to your model from the controller…

$model = new Application_Model_MyModel;
$model->setUrlHelper($this->_helper->getHelper('url'));

or let the lazy loader fetch it statically from the helper broker.
