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：

人员表

• id：主键
• 名称：字符
• room_number: int
• 电子邮件：字符

用户表

• id：主键
• person_id：Person Table (id) 的外键
• 密码：字符

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 类是使用错误的路径添加的，Model/Model/Person.php

PathFinder_Exception

干杯。

更新

代码片段需要进入 User 类，所以现在看起来像这样：

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：

选择id,person_id,(选择name from person where user.person_id = person.id) person_str from user

---

但是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');

}
}

所以我不太了解该功能并需要其余代码： $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。

Answer 1

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”无法处理预先创建的对象。
