我正在建立一个在线商店。我正在尝试实现一个 has_one : has_many 关系的 DataObjects 正在使用 ModelAdmin 和单选按钮（Silverstripe 中的 OptionsetField）进行管理，但我有 2 个问题。
当我在 CMS 中单击保存时，关系值没有保存到数据库中。
该状态不会持续存在，因此当我下次登录 CMS 时，我可以看到我上次选择了哪个单选按钮。
接下来是我的代码
---- 模型管理员 ----
<?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;
}
- - 类别 - -
<?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'),
1
)
)//close array of fields
);//end adding fields to main tab
return $fields;
}
}
---- 产品子类别 ----

/**

* Category
*
*/
private static $has_one = array(
'Category' => 'ProductCategory'
);//will lead to creation of column BoysPageID on the table BoysCategory
private static $has_many = array (
'Products' => 'Product'
);
public function getCMSFields(){
$fields = FieldList::create(TabSet::create('Root'));
$fields->addFieldsToTab('Root.Main', array(
TextField::create('Title', 'Name of Sub Category'),
DropdownField::create(
