SilverStripe page create error Class 'DateField' not found

Question

Im creating new SilverStripe project based on the tutorial of SilverStripe.

After adding this code, the CMS field dont show and gives error.

class ArticlePage extends Page {
private static $db = array(
    'Date' => 'Date',
    'Author' => 'Text',
);

// .....

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

    $dateField = new DateField('Date', 'Article Date (for example: 20/12/2010)');
    $dateField->setConfig('showcalendar', true);
    $dateField->setConfig('dateformat', 'dd/MM/YYYY');

    $fields->addFieldToTab('Root.Main', $dateField, 'Content');
    $fields->addFieldToTab('Root.Main', new TextField('Author', 'Author Name'), 'Content');

    return $fields;
}

}

the error is:

Fatal error: Class 'DateField' not found in sample/sample/ line*

I don't see any problem with the code as I copy it from the tutorial itself. please help

Does your file have a namespace? Also, are you following SilverStripe 3 tutorials but in a SilverStripe 4 project? Can you share the contents of composer show in your terminal? — scrowler
i mean both of them, no matter what code I copy gives the same error — Urek Mazino
4 would require a namespace, 3 should work. Can you provide more code to reproduce the problem? — scrowler
can you please explain about the namespace. im just new with the framework — Urek Mazino
