This is a pattern normally used with "slugs". You could use the
SluggableBehavior to automatically create a slug, but, in this case,
all of the planets have single-word names so maybe that's unnecessary.
Router::connect(
'/planets/:name',
array(
'controller' => 'planets',
'action' => 'view'
),
'name' => '[a-zA-Z]+',
'pass' => array('name')
);
Be sure to include routes for 'add', 'edit', etc. actions before this
one of the regexp will match on those too.
view (say your data is in variable $d):
echo $this->Html->link(
$d['Planel']['name'],
array(
'controller' => 'planets',
'action' => 'view',
'name' => $d['name']
),
array('title' => 'view planet info')
);
controller:
public function view($name = null)
{
if (!empty($name)
{
$this->redirect(array('action' => 'index'));
}
$this->set(
'data',
$this->Planet->fecthByName($name)
);
}
model:
public function fetchByName($name)
{
return $this->find(
'first',
array(
'conditions' => array(
'Planet.name' => $name
)
)
);
}
