我正在尝试创建一个新模型，该模型连接到表并使用 CRUD 呈现它们，遵循此示例。

我错过了什么？这不适用于a）文件存储吗？b) 增删改查？或 c）？

有一个客户联系表：

class Model_Contact extends Model_Table {
   public $table='customercontact';
       function init(){
          parent::init();

          $this->addField('ContactDate')->type('date')->caption('Contact Date');
          $this->addField('ContactNotes')->caption('Notes');

        }
}

还有一个联系附件表：

class Model_ContactAttachments extends Model_Table {
       public $table='contactattachments';
           function init(){
              parent::init();

              $this->addField('ContactID');
              $this->add('filestore/Field_File','FilestoreID')->caption('Upload File');
           }
    }

这是组合表，按照我理解的示例：

class Model_Contact extends Model_Table {
   public $table='customercontact';
       function init(){
          parent::init();

          $this->addField('ContactDate')->type('date')->caption('Contact Date');
          $this->addField('ContactNotes')->caption('Notes');

          $detail = $this->join('ContactAttachments.ContactID');
          $detail->add('filestore/Field_File','FilestoreID')->caption('Upload File');

       }
}

导致此错误：

应用程序错误：未为此对象定义方法

异常逻辑，代码：0

在加入时，您必须使用表名，而不是类名

function join($foreign_table, $master_field=null, $join_kind=null, $_foreign_alias=null,$relation=null){
