Silverstripe 将数据对象添加到 Siteconfig

Question

我正在尝试将数据对象添加到站点配置（设置）。我已经设法添加了一个徽标字段，现在可以使用了我想添加一些转发器字段，例如（社交媒体字段）。这是行不通的。我收到一个错误。

下面的代码和错误。我查看了数据库，所有字段都在 dev/build 之后创建。我也有 Flush=all.

mysite/_config/app.yml

SiteConfig:
 extensions:
  - CustomSiteConfig

mysite/code/extensions/CustomSiteConfig.php

class CustomSiteConfig extends DataExtension {

private static $has_one = array(
    'Logo' => 'Image'
);

private static $has_many = array(
    'SocialMedia' => 'SocialMedia'
);


public function updateCMSFields(FieldList $fields) {

    $fields->addFieldToTab("Root.Main", new UploadField('Logo', 'Logo'));
    $fields->addFieldToTab('Root.Main', $this->getSocialMedia());

}

protected function getSocialMedia() {
    $gridFieldConfig = GridFieldConfig::create()->addComponents(
        new GridFieldToolbarHeader(),
        new GridFieldAddNewButton('toolbar-header-right'),
        new GridFieldSortableHeader(),
        new GridFieldDataColumns(),
        new GridFieldPaginator(10),
        new GridFieldEditButton(),
        new GridFieldDeleteAction(),
        new GridFieldDetailForm(),
        new GridFieldSortableRows('SortID')
    );

    $gridField = new GridField("SocialMedia", "SocialMedia", $this->SocialMedia(), $gridFieldConfig);

    return $gridField;
}

}

mysite/code/extensions/SocialMedia.php

class SocialMedia extends DataObject { 

    public static $db = array( 
        'SortID' => 'Int',
        'Social' => 'Text',
        'Icon' => 'Text',
        'URL' => 'Text'
    );

    public static $has_one = array(
        'CustomSiteConfig' => 'CustomSiteConfig'
    );

    public function getCMSFields() {
        return new FieldList(
            new TextField('Social'),
            new TextField('Icon'),
            new TextField('URL')

        );

    }
}

错误信息

Fatal error: Call to undefined method CustomSiteConfig::SocialMedia() in file/path/mysite/code/extensions/CustomSiteConfig.php on line 34

第 34 行是

$gridField = new GridField("SocialMedia", "SocialMedia", $this->SocialMedia(), $gridFieldConfig);

Answer 1

在 decorator/DataExtension 上应该使用 $this->owner 而不是 $this。第 34 行应如下所示：

$gridField = new GridField("SocialMedia", "SocialMedia", $this->owner->SocialMedia(), $gridFieldConfig);
