Silverstripe CMS BlogPost - DropdownField 或 SingleSelectField 從枚舉欄位填入

Question

我正在嘗試在 BlogPost 摘要視圖中新增標題顏色選項。 我將枚舉字段添加到資料庫中，並且我想在 BlogPost 標題下添加下拉/選擇字段。 我不確定要使用哪種字段類型以及如何正確設置它。

class BlogPostExtension extends DataExtension
{
    private static $db = [
        'ArchiveDate' => 'Date',
        'TitleColor' => "Enum(array('black','red','green'))" // works only with this syntax
    ];

    private static $defaults = [
        'TitleColor' => 'black'
    ];


    public function updateCMSFields(FieldList $fields)
    {
        $fields->push(new DateField('ArchiveDate', 'Archive date'));
        $fields->push(new DropdownField('TitleColor','Color')); // doesn't populate the dropdown field
      //  $fields->push(new SelectField('TitleColor','Color'));   // cannot instantiate abstract class 'SelectField'
    }
}

Answer 1

如果有人有興趣 - 我是這樣解決的：

public function updateCMSFields(FieldList $fields)
{
    $fields->push(new DateField('ArchiveDate', 'Archive date'));
    $fields->push(new DropdownField('TitleColor','Color', $this->getEnums()));
}

private function getEnums() {
    return singleton('SilverStripe\Blog\Model\BlogPost')->dbObject('TitleColor')->enumValues();
}
