CakePHP Using Set::combine with localization

Question

I am trying to use the localization features in cakephp. In app_model.php I have a method that gets the different payment methods.

function getDistinctFields($model, $field)
{
    $list = ClassRegistry::init($model)->find('all', array(
        'fields'=>array("DISTINCT $model.$field"), 
        'conditions' => array('not' => array("$model.$field" => null))
    ));
    debug($list);
    $translated = "{n}.$model.$field";
    $return = Set::combine($list, "{n}.$model.$field", __($translated, true));
    return $return;
}

The result of the debug($list) looks like this:

[0] => Array
    (
        [InstantPaymentNotification] => Array
            (
                [payment_status] => Pending
            )
    )

[1] => Array
    (
        [InstantPaymentNotification] => Array
            (
                [payment_status] => Completed
            )
    )

[2] => Array
    (
        [InstantPaymentNotification] => Array
            (
                [payment_status] => Denied
            )
    )

[3] => Array
    (
        [InstantPaymentNotification] => Array
            (
                [payment_status] => Refunded
            )
    )

The output of the method looks like this:

> Array (
>     [Pending] => Pending
>     [Completed] => Completed
>     [Denied] => Denied
>     [Refunded] => Refunded
>     [Reversed] => Reversed
>     [Canceled_Reversal] => Canceled_Reversal )

Nicer, but the value is not translated as it should be. I created the default.po file in the correct location and tested to see if it works on other pages. However, it seems it doesn't work with the Set class.

You need to manually localize within a foreach after calling Set::combine. What you're currently doing is localizing the string "{n}.InstantPaymentNotification.payment_status", then sending that value into the Set::combine function.

You need to do something more like this:

function getDistinctFields($model, $field) {
    $list = ClassRegistry::init($model)->find('all', array(
        'fields'=>array("DISTINCT $model.$field"), 
        'conditions' => array('not' => array("$model.$field" => null))
    ));
    $list = Set::combine($list, "{n}.$model.$field", "{n}.$model.$field");
    foreach ($list as &$item) {
        $item = __($item, true);
    }
    return $list;
}
