Cakephp: Associations not working - cakephp

Question

I want to do a simple cakephp association program but it's not working.
I have two database tables: users and sec_datas. When i run this program it just shows the result of first row of users table, not the result of both tables which have same sec_id value.
Controller code:
<?php
class UsersController extends AppController
{
public function index()
{
$this->autoRender = FALSE;
$this->loadModel('User');
$storeDivisions = $this->User->find();
echo "<pre>";
print_r($storeDivisions);
echo "</pre>";
}
}
Model code:
<?php
class User extends AppModel {
public $useTable='users';
public $hasOne = array(
'Sec_data' => array(
'ClassName' => 'Sec_data',
'Conditions' => array('User.sec_id=Sec_data.sec_id'),
'Dependent' => false
)
);
}
?>

Answer 1

If the primary key of User model is id then cake try to associate the foreign key in Sec_data with that key regardless the conditions you set.
First of all you should do domething like
public $hasOne = array(
'Sec_data' => array(
'ClassName' => 'Sec_data',
'ForeignKey' => 'sec_id',
'Dependent' => false
)
);
But it would work only if sec_id is related to User.id
if you want Sec_data.sec_id related to User.sec_id (and User.sec_id is different from User.id) then you have to join the tables manually

Answer 2

There are a couple of things going wrong here. You should read up on CakePHP's conventions.
Your associated model class should be called SecData, then it will automatically map to the sec_datas table.
No need to use loadModel.
No need to specify conditions. Set the correct recursive level instead.
For hasOne, only one table has a foreign key. By default, the other Model has it ("User hasOne SecData" -> SecData has foreign key). So in your example, you should remove the column sec_id from User, and add a user_id column to your SecData Model.

Updated Controller code:
<?php
class UsersController extends AppController {
public $uses = array('User'); // Do this instead of loadModel
public function index() {
$this->autoRender = FALSE;
$this->User->recursive = 1; // Make User load associated records
$storeDivisions = $this->User->find('all');
pr($storeDivisions); // pr() is a Cake shorthand for print_r wrapped in <pre>
}
}
For your model:
<?php
class User extends AppModel {
// Unecessary. Convention is to use lowercase classname + 's', which
// already gives us 'users'
// public $useTable='users';
public $hasOne = array(
'SecData' => array( // Model class Sec_Data must be renamed accordingly
'dependent' => false
)
);
}
?>
