There is another that I found.
Model::hasAny
Returns true if a record that meets given conditions exists.
function hasAny($conditions = null) {
return ($this->find('count', array('conditions' => $conditions, 'recursive'
=> -1)) != false);
}
Which I guess is pretty much the same as my validPost($id) except cleaner.
public function validPost($id)
{
$valid = false;
$params = array(
'contain' => false,
'conditions' => array(
'Post.id' => $id),
'fields' => array(
'Post.id'));
$q = $this->find('first', $params);
if (!empty($q)) {
$valid = true;
}
return $valid;
}

I think you can use the models method getNumRows() which returns the number
of rows returned in the last query!
Enjoy,
