$hasMany

http://book.cakephp.org/ja/view/82/hasMany
例）
１ユーザに対して複数のコメントが存在する。

<?php

class User extends AppModel {
    var $name = 'User';                
    var $hasMany = array(
        'Comment' => array(
            'className'     => 'Comment',
            'foreignKey'    => 'user_id',
            'conditions'    => array('Comment.status' => '1'),
            'order'    => 'Comment.created DESC',
            'limit'        => '5',
            'dependent'=> true
        )
    );  
}
?>

結果

(
[User] => Array
(
[id] => 121
[name] => Gwoo the Kungwoo
[created] => 2007-05-01 10:31:01
)
[Comment] => Array
(
[0] => Array
(
[id] => 123
[user_id] => 121
[title] => On Gwoo the Kungwoo
[body] => The Kungwooness is not so Gwooish
[created] => 2006-05-01 10:31:01
)
[1] => Array
(
[id] => 123
[user_id] => 121
[title] => More on Gwoo
[body] => But what of the ‘Nut? [created] => 2006-05-01 10:41:01
)
)
)

hasAndBelongsToMany (HABTM)

http://book.cakephp.org/ja/view/83/hasAndBelongsToMany-HABTM
３つのテーブルを結びつける

<?php

class Recipe extends AppModel {
    var $name = 'Recipe';   
    var $hasAndBelongsToMany = array(
        'Tag' =>
            array(
                 'className'              => 'Tag',
                 'joinTable'              => 'recipes_tags',
                 'with'                   => '',
                'foreignKey'             => 'recipe_id',
                'associationForeignKey'  => 'tag_id',
                'unique'                 => true,
                'conditions'             => '',
                'fields'                 => '',
                'order'                  => '',
                'limit'                  => '',
                'offset'                 => '',
                'finderQuery'            => '',
                'deleteQuery'            => '',
                'insertQuery'            => ''
            )
    );
}
?>
