Re: BeforeFind

I'd say that beforeFind should be used for thing that you want to run
at all times.

Instead of doing this in beforeFind you might want to create a custom
find which is a good way to enforce custom logic to the find operation
while leaving any associations and other internal queries alone.

As a simple example. To find blocked and not blocked items from a
table (using a simple "blocked" field) you can define this in your
model:

function find($type, $options = array()) {
switch ($type) {
case 'count_not_blocked':
case 'first_not_blocked':
case 'all_not_blocked':
$type = substr($type,0,strpos($type,'_'));
if ( !isset($options['conditions']) ){
$options['conditions'] = array();
}elseif ( !is_array($options['conditions']) ) {
$str = $options['conditions'];
$options['conditions'] = array($str);
}
$options['conditions'][] = array($this-
>alias.'.blocked'=>0);
break;

case 'count_blocked':
case 'first_blocked':
case 'all_blocked':
$type = substr($type,0,strpos($type,'_'));
if ( !isset($options['conditions']) ){
$options['conditions'] = array();
}
$options['conditions'][] = array($this-
>alias.'.blocked'=>1);
break;

case default:
break;
}

return parent::find($type, $options);
}

Then you can call:
$this->Modelname->find('all_blocked');
$this->Modelname->find('count_not_blocked');

There are several articles available detailing variations on this
concept. Among them:
http://cakebaker.42dh.com/2008/03/23/defining-custom-find-types/
http://www.pseudocoder.com/archives/2008/10/24/cakephp-custom-find-types/

I am not sure if something like this might suit your application but
it is a nice tool to use sometimes.
