I’m trying to create a reference manually from one Model to another model, using the example given in http://agiletoolkit.org/doc/modeltable/reference. I’m using the following tables and models:
Person Table
- id: primary key
- name: char
- room_number: int
- email: char
User Table
- id: primary key
- person_id: foreign key to Person Table (id)
- password: char
The ATK4.2 classes are below:
Person Model
class Model_Person extends Model_Table {
public $entity_code='person';
function init(){
parent::init();
$this->addField('name');
$this->addField('roomnumber');
$this->addField('email');
}
}
User Model
The ‘user’ table contains the password field.
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');
}
}
However, I’m getting the following error, where the Model_Person class is being added using the wrong path, Model/Model/Person.php
PathFinder_Exception
Unable to include Model/Model/Person.php

Cheers.
Update
The code fragment needs to go into the User class, so it now looks like this:
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');
}
}
The SQL produced is:
select id,person_id,(select name from person where user.person_id = person.id ) person_str from user
However the below class also produces the same SQL statemetn.
class Model_User extends Model_Table {
public $entity_code='user';
function init(){
parent::init();
$this->hasOne('Person');
$this->getField('person')->rename('person_str');
}
}
So I don’t quite understand the function and need for the rest of the code:
$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');
I hope we can get some further explanation on this, thank you.
try this inside your person model
otherwise “setmodel” is not working with pre-created objects.
