CakePHP - Only one Query from external Model - php

Question

I've two Models:
class Post extends AppModel {
var $name = 'Post';
var $belongsTo = array(
'User' => array(
'className' => 'User',
'foreignKey' => 'user_id'
)
);
}
and
class User extends AppModel {
var $name = 'User';
var $hasMany = 'Post';
}
Now I'm having a problem with a query in the PostsController. I've an add() function and the view add.ctp which is basically a form. Now I would like to show some User information in that form.
class PostsController extends AppController {
var $name = 'Posts';
var $helper = array('Html', 'Form');
var $uses = array('User');
public function index() {
$this->set('posts', $this->Post->find('all'));
}
function add() {
$user_id = 1;
$this->set('user', $this->User->findById($user_id));
if ($this->request->is('post')) {
if ($this->Post->save($this->request->data)) {
$this->Session->setFlash('Your post has been saved.');
$this->redirect(array('action' => 'index'));
} else {
$this->Session->setFlash('Unable to add your post.');
}
}
}
}
But now the add-view-page shows that actually two queries where triggered. So if I print_r($user) within the add-view I'm getting an array with two arrays. One for a Post with user_id = 1 and one for the actual User with id = 1. But I would like to get only the User id = 1.

Try setting recursive to false on the User model before calling findById, so you won't get any data from associated models. Like this:
function add() {
$user_id = 1;
$this->User->recursive = false;
$this->set('user', $this->User->findById($user_id));
if ($this->request->is('post')) {
if ($this->Post->save($this->request->data)) {
$this->Session->setFlash('Your post has been saved.');
$this->redirect(array('action' => 'index'));
} else {
$this->Session->setFlash('Unable to add your post.');
}
}
}
