Cakephp - joining tables, NOT in - cakephp

Question

I'm a newbie and I'm trying to make a Query but don't get it how to do the Query in cake-style. I want to do a query that Selects all respondents thats not in a particular transformational. Examples at the bottom. Cakephp v 2.4.5
I have to three tables/models:
Resondents: id, name
public $hasAndBelongsToMany = array(
'Transformational' => array(
'className' => 'Transformational',
'joinTable' => 'transformationals_respondents',
'foreignKey' => 'respondent_id',
'associationForeignKey' => 'transformational_id',
'unique' => true
)
);
Transformationals: id, name
public $hasAndBelongsToMany = array(
'Respondent' => array(
'className' => 'Respondent',
'joinTable' => 'transformationals_respondents',
'foreignKey' => 'transformational_id',
'associationForeignKey' => 'respondent_id',
'unique' => true
),
};
TransformationasRespondent: id, transformational_id, respondent_id
This is a join table
Example tables:
respondent: id, name
1, Abc
2, Def
3, Ghi
4, Jkl
transformationals: id, name
1, Macrosoft
2, Eddy
3, Wag
transformationals_respondents: id, respondent_id, transformational_id
1, 1, 7
2, 2, 7
THen I need Query to SELECT respondents thats NOT in transformationals_respondents and has transformational_id 7. Ie. respondent Ghi and Jkl
I would really appreciate a hand here.

Answer 1

Create one function in Respondent model as
function getSomeSome(){
$options = array(
'conditions' => array('Transformational.id'=>7,'TransformationasRespondent.id IS NULL'),
'joins' => array(
array(
'alias' => 'TransformationasRespondent',
'table' => 'transformationals_respondents',
'type' => 'LEFT',
'conditions' => array(
'TransformationasRespondent.respondent_id = Respondent.id',
),
),
array(
'alias' => 'Transformational',
'table' => 'transformationals',
'type' => 'LEFT',
'conditions' => array(
'TransformationasRespondent.transformational_id = Transformational.id',
),
),
)
);
$returnData = $this->find('all',$options);
# returnData contains all the records having transformational_id equals to 7 and
# does nt have any recors in TransformationasRespondent table
}
