CakePHP update a child model from parent - cakephp

Question

I am currently struggling to get an associated model to update with CakePHP 2.3. I want the parent model to be inactive, and the child model record to be inactive. I have the following method in my Company Model, which just updates the parent model (and not the child). What is the best way to achieve this? I tried moving the method to the child object, but it makes no difference.
class Company extends AppModel {
public $hasMany = array(
'CompaniesUser' => array(
'className' => 'CompaniesUser'
)
);
function updateToInactive( $companyId ){
$data = array(
array(
'Company' => array(
'id' =>$companyId,
'active' => 0,
'payment_active'=> 0
),
'CompaniesUser' => array(
'company_id' =>$companyId,
'active' => 0)
)
);
$this->saveAll($data);
}
}
My CompaniesUser Model looks like this:( belongs to Company )
class CompaniesUser extends AppModel {
public $belongsTo = array(
'Company' => array(
'className' => 'Company',
'foreignKey' => 'company_id'
)
);

Answer 1

Your $data array looks wrong to me for a hasMany relationship. It should look something more like this:-
$data = array(
'Company' => array(
'id' =>$companyId,
'active' => 0,
'payment_active'=> 0
),
'CompaniesUser' => array(
array(
'company_id' =>$companyId,
'active' => 0
)
)
);
$this->saveAssociated($data);
It is also better to use saveAssociated() than saveAll() as you are saving associated data.
Update
The above will not update the existing CompaniesUsers unless you pass the primary keys with the save data. You could save the company first then use updateAll() to update the users data for the related company. If you use updateAll() you need to remember to escape the values being saved:-
// Update company
$data = array(
'id' =>$companyId,
'active' => 0,
'payment_active'=> 0
);
$this->save($data);
// Update company users
$this->CompaniesUser->updateAll(
array('CompaniesUser.active' => '"0"'),
array('CompaniesUser.company_id' => '"' . $companyId . '"')
);
