Thanks for all of the ideas. Here's what I ended up doing, which works
great and does not break MVC :)
In the AppController:
function beforeFilter() {
// put the latest published schedule into the session
if (!$this->Session->check('Schedule')) {
$schedule = ClassRegistry::init('Schedule')->find('first',
array('order' => 'id desc')
);
$this->Session->write('Schedule', $schedule['Schedule']);
}
$this->{$this->modelClass}->schedule_id = $this->Session-
>read('Schedule.id');
}
And then in the AppModel:
var $schedule_id;
function contain() {
$args = func_get_args();
foreach($args as &$arg) {
$arg .= '.schedule_id = ' . $this->schedule_id;
}
parent::contain($args);
}
function find($type, $params = array()) {
if ($this->name != 'Schedule') {
if (array_key_exists('contain', $params)) {
foreach($params['contain'] as &$contain) {
$contain .= '.schedule_id = ' . $this->schedule_id;
}
}
$params = array_merge_recursive(
$params,
array(
'conditions' => array(
"{$this->name}.schedule_id" => $this->schedule_id
)
)
);
if (isset($this->id)) {
$params['conditions']["{$this->name}.id"] = $this->id;
}
}
return parent::find($type, $params);
}
Now I can use the ideal shorter code from my first message on this
thread!
Next is to adapt it for saves and deletes as well.
Could this be a good solution for people who want to use composite
primary keys?
