Re: CakePHP and a normalized database

Hi, the following should help (for v1.3)

It joins the User to the Person and then to the Address.. linking the rest of the tables should be similar.

<?php

class User extends AppModel {
var $name = 'User';

var $hasOne = array(
'Person' => array(
'className' => 'Person',
'foreignKey' => 'id',
'dependent' => true,
),
'Address' => array(
'className' => 'Address',
'foreignKey' => false,
'type' => 'LEFT',
'conditions' => array('Address.id = Person.address_id')
)
);

}

?>

If you use the foreignKey option when trying to link in Address, it tries to match the User.id to the Address.id, hence why I've set the condition instead. I was hoping that you could do nested 'hasOne' options, but doesn't seem so..
