php - PathFinder_Exception 无法使用 setModel 包含模型/模型/

Question

我正在尝试使用http://agiletoolkit.org/doc/modeltable/reference中给出的示例手动创建从一个模型到另一个模型的引用。我正在使用以下表格和模型：

人表

id：主键
名称：字符
房间号：整数
电子邮件：char

用户表

id：主键
person_id：人表的外键（id）
密码：char

ATK4.2类如下：

人物模型

class Model_Person extends Model_Table {
public $entity_code='person';

function init(){
    parent::init();
    $this->addField('name');
    $this->addField('roomnumber');
    $this->addField('email');
}
}

用户模型

“用户”表包含密码字段。

class Model_User extends Model_Table {
public $entity_code='user';

function init(){
    parent::init();

    $field_ref = $this->add('Field_Reference', 'person_id');
    $field_ref->dereferenced_field = 'person_str';
    // add referenced Model
    $m = $this->add('Model_Person');
    $m->addField('name');
    // Link referenced model field name to this model field.
    $field_ref->setModel($m, 'name');


}
}

但是，我收到以下错误，其中 Model_Person 类正在使用错误的路径 Model/Model/Person.php 添加

PathFinder_Exception

Unable to include Model/Model/Person.php

干杯。

更新

代码片段需要进入 User 类，所以它现在看起来像这样：

class Model_User extends Model_Table {
public $entity_code='user';

function init(){
    parent::init();

    $this->hasOne('Person');

    $field_ref = $this->getField('person')->rename('person_str');
    $this->getField('person_id')->dereferenced_field='person_str';

    // add referenced Model
    $m = $this->add('Model_Person');
    $m->addField('name');

    // Link referenced model field name to this model field.
    $field_ref->setModel($m, 'name');

}
}

产生的 SQL 是：

select id, person_id,(select namefrom personwhere user. person_id= person. id) person_strfromuser

然而，下面的类也产生相同的 SQL 语句。

class Model_User extends Model_Table {
public $entity_code='user';

function init(){
    parent::init();

    $this->hasOne('Person');

    $this->getField('person')->rename('person_str');

}
}

所以我不太了解其余代码的功能和需求： $this->getField('person_id')->dereferenced_field='person_str';

    // add referenced Model
    $m = $this->add('Model_Person');
    $m->addField('name');

    // Link referenced model field name to this model field.
    $field_ref->setModel($m, 'name');

我希望我们能对此得到进一步的解释，谢谢。

在你的人物模型中试试这个

$this->hasOne('Person');
$this->getField('person')->rename('person_str');
$this->getField('person_id')->dereferenced_field='person_str';

否则“setmodel”不适用于预先创建的对象。

php - PathFinder_Exception 无法使用 setModel 包含模型/模型/

人物模型

用户模型

“用户”表包含密码字段。
