我正在建立一個在線商店。我正在嘗試通過使用單選按鈕（Silververstripe中的OptionsetField）來管理使用ModelAdmin來管理DataObject的has_one：has_many關係，但我有兩個問題。Silverstripe框架模型管理，數據對象關係和OptionsetField保存到數據庫中
當我點擊保存在CMS中時，關係值沒有保存到數據庫中。
狀態不會持續，因此當我下次登錄CMS時，可以看到上次選擇哪個單選按鈕。
接下來是我的代碼
----型號聯繫----
<?php
class ProductAdmin extends ModelAdmin {
private static $menu_title = 'Store Manager';
private static $url_segment = 'StoreManager';
private static $managed_models = array (
'Product'=>array('title'=>'All Store Products'),
'ProductCategory'=>array('title'=>'Product Categories'),
'ProductSubcategory'=>array('title' => 'Product Sub Categories')
);
public $showImportForm = false;
}
---- ----類
<?php
class ProductCategory extends DataObject {
private static $db = array (
'Title' => 'Varchar',
);
/**
* This relation links the Category to the Menu Items e.g. Category BoysClothing will be related to Boys * Menu Item.
*/
private static $has_one = array(
'Page' => 'Page'
);
private static $has_many = array (
'Subcategories' => 'ProductSubcategory'
);
public function getCMSFields(){
$fields = FieldList::create(TabSet::create('Root'));
$fields->addFieldsToTab('Root.Main', array(
TextField::create('Title', 'Name of Category'),
OptionsetField::create(
'Page', //name
'Page this category belongs to', //title
SiteTree::get()->filter(array('ShowInMenus' => '1'))->map('ID', 'Title'),
