Cakephp: multiple levels of belongsto in model - php

Question

In a model, is it possible to do multiple iterations of belongsTo?
Assuming 3 tables, alerts, schedules, tasks and the model is for alerts. I want to get at a field from tasks but I have to join through schedules.
alerts.schedule_id -> schedules.tasks_id -> tasks.name
I tried this syntax:
var $belongsTo = array(
'Schedule' => array(
'className' => 'Schedule',
'foreignKey' => 'schedule_id'
),
'Task' => array(
'className' => 'Task',
'foreignKey' => 'task_id'
));
But that just joins both Schedules and Tasks directly to Alerts (here's the sql that was generated:
LEFT JOIN `schedules` AS `Schedule` ON (`Alert`.`schedule_id` = `Schedule`.`id`) LEFT JOIN `tasks` AS `Task` ON (`Alert`.`task_id` = `Task`.`id`)
)

Answer 1

I ended up setting this property:
$this->Alert->recursive = 2;
In the index() function of the alerts controller.
Then I didn't have to do a separate find and was able to reference the name field in the Tasks table in index.ctp like this:
<td><?php echo $alert['Schedule']['Task']['name']; ?> </td>

Answer 2

Try this.
in alert.php
CLass Alert extends AppModel{
var $name = 'Alert';
var $belongsTo = array(
'Schedule' => array(
'className' => 'Schedule',
'foreignKey' => 'schedule_id'
)
);
}
in schedule.php
CLass Schedule extends AppModel{
var $name = 'Schedule';
var $belongsTo = array(
'Task' => array(
'className' => 'Task',
'foreignKey' => 'task_id'
)
);
}
then find with recursive=>2
