Cake's routes default to:

/controller/action/param

So, if you had a BookController, to view a specific Book, you'd have
something like:

/books/view/42

... where 42 is the $id of this Book. However, you might instead want
to have URLs like:

/books/alice-in-wonderland

... in which case, you'd want a route like so:

Router::connect(
'/books/:slug',
array(
'controller' => 'books',
'action' => 'view',
),
array(
'slug' => '[-a-z0-9]+',
'pass' => array('slug')
)
);

So, Book.slug must be contain only lowercase alpha chars, integers, or
hyphens. And your Book model would have:

public $actsAs = array(
'Sluggable' => array(
'translation' => 'utf-8',
'separator' => '-',
'label' => 'title',
'length' => 64,
'overwrite' => true
)
);

Note the separator is a hyphen. It can also be an underscore, or
whatever. Just ensure the route regexp is set up for that.

Your action would then be defined as:

public function view($slug = null) {

Meanwhile, to create a link in a view (other mark-up aside):

foreach ($data as $d)
{
echo $this->Html->link(
$d['Book']['title'],
array(
'controller' => 'books',
'action' => 'view',
'slug' => $d['Book']['slug']
),
array('title' => 'read this book')
);
}

Note that 'slug' is passed in the first array, whereas it's in the
second array in the route definition. If it's an admin route, you pass
'admin' => 1 in the first array for both link and route, and the URL
would be '/admin/...' inthe route.
