Silverstripe CMS BlogPost - DropdownField 或 SingleSelectField 从枚举字段填充

Question

我正在尝试在 BlogPost 摘要视图中添加标题颜色选项。 我将枚举字段添加到数据库中，并且我想在 BlogPost 标题下添加下拉/选择字段。 我不确定要使用哪种字段类型以及如何正确设置它。

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

如果有人感兴趣 - 我是这样解决的：

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();
}
