How to use SEO urls in CakePHP without the ID

CakePHP offers massive support to create SEO friendly URLs on the fly. You can create SEO-friendly-urls without an ID value to refer to specific post id. It works like a charm like many other Cake MAGIC!

I'll refer to the post table.
1. Create a field called 'slug' (must be UNIQUE and NOT NULL) in the post table.

2. Download and use sluggable behavior to create post slug! Follow instructions step-by-step. It works perfectly.

3. Define routing rules in config/router.php file to display SEO friendly urls.

Router::connect(


       '/posts/:slug',


       array(


               'controller' => 'posts',


               'action' => 'view'


       ),


       array(


               'slug' => '[-a-z0-9]+',


               'pass' => array('slug')


       )


);

4. In posts_controller.php view() function modify query,

function view($slug = null)
{
        if (empty($slug))
        {
                // redirect ...
        }
    
         $data = $this->Post->findBySlug($slug) ; 
      
}

You you should be able to access urls of the form:
http://example.com/your-seo-friendly-post-url/

Hope it helps someone.
