slugExists

[FrodeMMeling]

The Sluggable behavior should have an exists method like CakeModel has for id. This will make it easier to convert scaffolded code to slug.

Here is a function that works (simplified version of CakeModel::exists)

    public function slugExists($slug = false) {
        if ($slug === false) {
            return false;
        }

        return (bool)$this->find('count', array(
            'conditions' => array(
                $this->alias . '.' . 'slug' => $slug
            ),
            'recursive' => -1,
            'callbacks' => false
        ));
    }

you can then in view action write:

    public function view($slug = null) {
        if (!$this->Asset->slugExists($slug)) {
            throw new NotFoundException(__('Invalid asset'));
        }
        $options = array('conditions' => array('Asset.' . 'slug' => $slug));
        $this->set('asset', $this->Asset->find('first', $options));
    }

You could just use $this->Asset->findBySlug($slug) in this case.

Yes, i know, but I think the find count is much faster when you have large amount of records.
