Translating a DataObject using the _t() method?

Question

I am trying to translate a DataObject using the _t() method.

I have been using it on Pages without a problem, but it doesn't seem to work on data objects.

class SliderItem extends DataObject {

    private static $default_sort = 'Sort';

    private static $db = array(
        'Sort' => 'Int',
        'Title' => 'Varchar(255)',
        'Summary' => 'Text'
    );


    public function getCMSFields() {
        $fields = parent::getCMSFields();
        $fields->addFieldsToTab('Root.Main', array(
            TextField::create(_t('SliderItem.Title', 'Title')),
            TextareaField::create(_t('SliderItem.Summary', 'Summary'))
        ));
        $fields->removeByName(array('HomePageID', 'Sort'));
        return $fields;
    }
}

mysite/lang/de.yml

de:
  SliderItem:
    Title: 'I want to change this'
    Summary: 'And this..'

Why does this example not work?

Make sure to define the variable name in the FormField constructor as the first parameter and the translatable title as the second parameter.

This:

TextField::create(_t('SliderItem.Title', 'Title'))

Should be this:

TextField::create('Title', _t('SliderItem.Title', 'Title'))

Your getCMSFields function should look something like this:

public function getCMSFields() {
    $fields = parent::getCMSFields();

    $fields->addFieldsToTab('Root.Main', array(
        TextField::create('Title', _t('SliderItem.Title', 'Title')),
        TextareaField::create('Summary', _t('SliderItem.Summary', 'Summary'))
    ));

    $fields->removeByName(array('HomePageID', 'Sort'));

    return $fields;
}
