Question

我想在 CMS 中向我的滑块添加小图像。目前我这里的东西对我有用，我有一张大图片：

class Banner extends SortableObject {

    private static $db = array(
    );

    private static $has_one = array(
        'HomePage' => 'HomePage',
        'Image' => 'Image',
        'Target' => 'Page',
    );

    private static $summary_fields = array(
        'ID',
        'Target.MenuTitle',
    );

    public function getCMSFields() {
        $fields = new FieldList();

        $img = new UploadField('Image');
        $img->setFolderName('hpbanners');
        $img->getValidator()->setAllowedExtensions(array('jpg','gif','png'));
        $fields->push($img);

        $drop = new TreeDropdownField('TargetID','Choose page','SiteTree');
        $fields->push($drop);

        return $fields;
    }
}

现在我想添加另一个字段。我添加了 $smallImage，据我所知这应该在数据库中添加新列，就像之前的图像一样，但我的问题是在数据库 table 中我只有第一张图片，没有添加第二张图片：

class Banner extends SortableObject {

    private static $db = array(
    );

    private static $has_one = array(
        'HomePage' => 'HomePage',
        'Image' => 'Image',
        'SmallImage' => 'SmallImage',
        'Target' => 'Page',
    );

    private static $summary_fields = array(
        'ID',
        'Target.MenuTitle',
    );

    public function getCMSFields() {
        $fields = new FieldList();

        $img = new UploadField('Image');

        $img->setFolderName('hpbanners');
        $img->getValidator()->setAllowedExtensions(array('jpg','gif','png'));
        $fields->push($img);

        $smallImage = new UploadField('SmallImage');
        $smallImage->getValidator()->setAllowedExtensions(array('jpg','gif','png'));
        $fields->push($smallImage);

        $drop = new TreeDropdownField('TargetID','Choose page','SiteTree');
        $fields->push($drop);

        return $fields;
    }
}

所以请告诉我，因为我知道此列会自动添加，我应该清除缓存还是我做错了什么？帮我！ :)

Answer 1

关系总是'YourRelationName' => 'Type'的形式。所以你的 $has_one 关系定义应该是：

private static $has_one = array(
    'HomePage' => 'HomePage',
    'Image' => 'Image',
    'SmallImage' => 'Image', // Use type 'Image', not 'SmallImage'
    'Target' => 'Page',
);
