我正在尝试使用http://agiletoolkit.org/doc/modeltable/reference中给出的示例手动从一个模型创建一个引用到另一个模型。我正在使用以下表格和模型:
人员表
用户表
ATK4.2课程如下:
class Model_Person extends Model_Table {
public $entity_code='person';
function init(){
parent::init();
$this->addField('name');
$this->addField('roomnumber');
$this->addField('email');
}
}
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类使用错误的路径添加,Model / Model / Person.php
PathFinder_Exception

干杯。
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');
}
}
生成的SQL是:
选择id
,person_id
,(从name
person
选择user
。person_id
= person
。{{来自id
person_str
但是,下面的类也会生成相同的SQL statemetn。
user
所以我不太了解其余代码的功能和需求: $这 - > getfield命令( 'PERSON_ID') - > dereferenced_field = 'person_str';
class Model_User extends Model_Table {
public $entity_code='user';
function init(){
parent::init();
$this->hasOne('Person');
$this->getField('person')->rename('person_str');
}
}
我希望我们能对此有进一步的解释,谢谢。
答案 0 :(得分:0)
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”不能与预先创建的对象一起使用。
