ZF: performing redirect inside model

Question

I've chosen to move Form processing from Controller to MyForm class, in order to follow ThinController/FatModel rule. But some of my code in Zend_Form class needs to perform a redirect.

In Zend_Controller_Action my redirect was:

$this->_redirect('/');

What would it become in Zend_Form?

Answer 1

$redirector =
    Zend_Controller_Action_HelperBroker::getStaticHelper('redirector');
$redirector->gotoSimple('index','index');

Answer 2

It's not a model component, if you redirect from within it. You should only do redirects from the presentation layer.

What would be an example of this? Lets suppose that currently I have a simple RecordForm class, and in its init() I am doing redirect after lines where I check record update was successfull.

You could let the function return a value indicating success/failure, and let the caller (the controller) perform a redirect based on the result.
