实现 SilverStripe 应用中 CQRS 工作流程的实用模块。

⚠️ 这是一个正在进行中的项目，目前还不能使用或进行试验！我们正在项目中测试这个项目，一旦达到足够的增值，我们将提供稳定的构建版本。

读取有效载荷清单

读取有效载荷清单定义了基于类存储的数据。

示例清单（《$read_payload》）

class MyObject extends DataObject {

    private static $db = [
        'Title' => 'Varchar',
        'Teaser => 'Text',
        'Content => 'HTMLText'
    ];
    
    private static $has_many = [
        'Categories' => Category::class
    ];
    
    private static $read_payload = [
        'ID',                         // required
        'Title'      => 'CoolTitle'   // required, maps to "CoolTitle()"
        'Teaser'     => false,        // not required
        'Content'    => true,         // required (non-shorthand)
        'Author',                     // required (method value)
        'Categories' => true,         // required recursive relation table
        'Tags'       => [             // not required, maps to "getMyTags()"
            'required' => false,
            'mapping' => 'getMyTags'
        ]
    ];
    
    public function CoolTitle() { ... }
    
    public function Author() { ... }
    
    public function getMyTags() { ... }
}
