PathFinder_Exception无法包含模型/模型/使用setModel
提问于 2012-05-01 01:19:58
我试图使用http://agiletoolkit.org/doc/modeltable/reference中给出的示例手动创建一个从一个模型到另一个模型的引用。我使用以下表格和模型：
人事表
char
- room_number：
- id:主键
- 名称：
- int
- 电子邮件: char
用户表
个人主key
- person_id:外键表(id)
- password: char
ATK4.2级课程如下：
人模型
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
“user”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，我得到了以下错误，其中使用错误的路径Model/Model/Person.php添加了Model_Person类

更新
代码片段需要进入User类，所以现在如下所示：
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');
}
}生成的SQL是：
选择id，person_id，(从person选择name .person_id= person.id )从user选择person_str
但是，下面的类也生成相同的SQL状态。
class Model_User extends Model_Table {
public $entity_code='user';
function init(){
parent::init();
$this->hasOne('Person');
$this->getField('person')->rename('person_str');
}
}因此，我不太理解该函数以及其余代码的需要：$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');我希望我们能得到进一步的解释，谢谢。

在你的人形模型里试试这个
$this->hasOne('Person');
$this->getField('person')->rename('person_str');
$this->getField('person_id')->dereferenced_field='person_str';否则，"setmodel“将无法处理预先创建的对象。
