I have a dataextension that adds fields to the database, all fine, but I also want to change an existing field Title, from varchar, to text, but it doesn't seem to pick this change up, and leaves it as a varchar

class EditableFormFieldDecorator extends DataExtension {
    static $db = array (
        "Title" => "Text",
        "ParentClass" => "Varchar"
    );

Is there anyway of overriding the field type? I really don't want to edit the core files...

OK, i found a way

instead of trying to change the field type in the in the DataExtension function, I update the db fields in the _config.php file:

$fields = Config::inst()->get('EditableFormField', 'db', Config::UNINHERITED);
$fields['Title'] = 'Text';
Config::inst()->update('EditableFormField', 'db', $fields);
