Data saving as blank in CakePHP - cakephp

Question

I have a foreach loop that saves a bunch of records into a table using cakePHP
foreach($interests as $id){
$this->data['UserInterest']['user_id'] = $user_id;
$this->data['UserInterest']['interest_id'] = $id;
$this->data['UserInterest']['other_interest'] = $other;
$UserInterest = new UserInterest;
if(!$UserInterest->save($this->data)) {
$this->Session->setFlash(__l('Failed to save Interests.') , 'default', null, 'error');
}
}
All saves fine except the other interest
UPDATE:
I've did the following
I can exho it out perfectly if I do this
$this->data['UserInterest']['other_interest'] = $other;
echo $this->data['UserInterest']['other_interest'];
$UserInterest = new UserInterest;
But somehow it saves as blank?
My database layout looks like this
CREATE TABLE IF NOT EXISTS `users_interests` (
`id` bigint(20) NOT NULL AUTO_INCREMENT,
`user_id` bigint(20) NOT NULL,
`interest_id` bigint(20) NOT NULL,
`other_interest` varchar(150) CHARACTER SET utf8 COLLATE utf8_unicode_ci NOT NULL,
PRIMARY KEY (`id`)
)
and my model like this
<?php
class UserInterest extends AppModel
{
var $name = 'UserInterest';
var $useTable="users_interests";
//$validate set in __construct for multi-language support
//The Associations below have been created with all possible keys, those that are not needed can be removed
var $belongsTo = array(
'User' => array(
'className' => 'User',
'foreignKey' => 'user_id',
'conditions' => '',
'fields' => '',
'order' => '',
) ,
'Interests' => array(
'className' => 'Interest',
'foreignKey' => 'interest_id',
'conditions' => '',
'fields' => '',
'order' => '',
)
);
function __construct($id = false, $table = null, $ds = null)
{
parent::__construct($id, $table, $ds);
$this->validate = array(
'user_id' => array(
'rule' => 'numeric',
'allowEmpty' => false,
'message' => __l('Required')
)
);
}
}
?>
Am I doing something wrong?
UPDATE:
I did the following
$this->data['UserInterest']['user_id'] = $user_id;
$this->data['UserInterest']['interest_id'] = $id;
$this->data['UserInterest']['other_interest'] = $other;
echo '<pre>';
var_dump($this->data['UserInterest']);
var_dump($other);
var_dump($this->data['UserInterest']['other_interest']);
$this->UserInterest = ClassRegistry::init('UserInterest');
And the var_dump results where the following, and still it did not save
array(3) {
["user_id"]=>
string(3) "659"
["interest_id"]=>
string(2) "10"
["other_interest"]=>
string(17) "Share Investments"
}
string(17) "Share Investments"
string(17) "Share Investments"

And old post but would like to add this here....
Always have
$this->Modelname->create();
in loops to save multiple records with loop. An most often this is the case which causes the error.
