In Kohana, can you trigger a 404 error?

Question

I have a controller called articles, which creates the articles model which gets the relevant data from the database.

I want to, if the method I call returns false, to trigger a 404 error. This is what I have so far.

 $articleName =  $this->uri->segment('articles');

 $article = new Articles_Model();

 $data = $article->getArticleUsingSlug($articleName);

 if (!$data) {
    Kohana::show_404; // This doesn't work.
 }

I just added my own custom hook which redirects the user to an actual 404 (/articles/page-not-found/) as triggered by Kohana, but is there a way I can invoke its internal 404 method to make Kohana give up processing my controller and use my new hook ?

@Nael El Shawwa Not when there are better options available. — alex, Feb 02 '11 at 13:31

As an update, in Kohana 3.3 it’s `throw new Kohana_HTTP_Exception_404()`. – Jezen Thomas Jun 05 '13 at 09:17

This works for me:

Event::run('system.404');

What version of Kohana are you using?

Also note that if $config['display_errors'] = TRUE; you will see a stack trace along with your 404 page. If you want JUST a 404 page to display set display_errors = FALSE – pifantastic May 06 '09 at 00:17

Kohana Docs tells you way to do it:

throw HTTP_Exception::factory(404, 'File not found!');
