Cake php multimodel form post parameters - cakephp

Question

I'm a cakephp newbie, and I was ordered to use the 1.3 version.
I can't understand (and both guides and api docs don't tell it) how I could create an HABTM association in a POST request.
I'm trying to create a wine, that could be made of many vines. For example I'm creating a "soave" whine, that is made of "garganega" and "chardonnay" vines.
How should the POST params should be?
Given theses models
class Wine extends AppModel{
var $hasAndBelongsToMany = array(
'Vine' => array(
'className' => 'Vine',
'joinTable' => 'wine_vines',
'foreignKey' => 'wine_id',
'associationForeignKey' => 'vine_id',
'with' => 'WineVine',
),
);
}
class Vine extends AppModel{
var $hasAndBelongsToMany = array(
'Wine' => array(
'className' => 'Wine',
'joinTable' => 'wine_vines',
'foreignKey' => 'vine_id',
'associationForeignKey' => 'wine_id',
'with' => 'WineVine',
),
);
}
class WineVine extends AppModel{
var $name = "WineVine";
public $belongsTo = array("Wine", "Vine");
}
I tried a POST like this:
Array
(
[Wine] => Array
(
[denomination] => Soave DOP
[fantasy_name] =>
[kind] => White
)
[Vine] => Array
(
[0] => Array
(
[name] => garganega
)
[2] => Array
(
[name] => chardonnay
)
)
)
but it does not perform any inserts in vine table, only in wine.
Here's the log:
2 INSERT INTO `wines` (`denomination`, `fantasy_name`, `kind`, `modified`, `created`) VALUES ('', '', '', '2013-10-25 17:27:14', '2013-10-25 17:27:14') 1 55
3 SELECT LAST_INSERT_ID() AS insertID 1 1 1
4 SELECT `WineVine`.`vine_id` FROM `wine_vines` AS `WineVine` WHERE `WineVine`.`wine_id` = 2 0 0 1
5 SELECT `Vine`.`id`, `Vine`.`name`, `Vine`.`created`, `Vine`.`modified` FROM `vines` AS `Vine` WHERE 1 = 1 5 5 0
6 SELECT `Wine`.`id`, `Wine`.`denomination`, `Wine`.`fantasy_name`, `Wine`.`kind`, `Wine`.`created`, `Wine`.`modified`, `Wine`.`producer_id`, `WineVine`.`id`, `WineVine`.`wine_id`, `WineVine`.`vine_id`, `WineVine`.`created`, `WineVine`.`modified` FROM `wines` AS `Wine` JOIN `wine_vines` AS `WineVine` ON (`WineVine`.`vine_id` IN (1, 2, 3, 4, 5) AND `WineVine`.`wine_id` = `Wine`.`id`)

Answer 1

after saving the wine, try injecting its id into the data array
$this->data['Wine']['id'] = $this->Wine->id;
and then call an overloaded Model::saveAssociated() that will save all vines and update the join table by itself.
this overloaded method is described at:

edit: sorry, that's for cake 2.x
i just realized 1.3 has no saveAssociated method
edit 2: but it does work in cake 1.3 if you change the last line of the saveAssociated method to
return parent::saveAll($data, $options);
