Question

My schema is quite simple-
Each user has an id and name.
There are jobs which belong to a user. Actual schema-

CREATE TABLE `users` (
   id INT UNSIGNED AUTO_INCREMENT PRIMARY KEY,  
  `name` varchar(20) 
) ENGINE=InnoDB DEFAULT CHARSET=latin1;


CREATE TABLE `jobs` (
   id INT UNSIGNED AUTO_INCREMENT PRIMARY KEY,
  `user_id` INT UNSIGNED ,
  `type` int,  
  FOREIGN KEY (user_id) references  users(id) 
) ENGINE=InnoDB DEFAULT CHARSET=latin1;

My JobsController looks like this-

<?php
class JobsController extends AppController {
    public $scaffold;
    public $name = 'Job';

    public $belongsTo = array(
        'User' => array(
            'className'    => 'User',
            'foreignKey'   => 'user_id'
        )
    );

}

And UsersController as-

<?php
class UsersController extends AppController {
    public $scaffold;
    public $name = 'User';


    public $hasMany = array(
        'Job' => array(
            'className'     => 'Job',
            'foreignKey'    => 'user_id'
        )
    );
}

Problem:

When I visit http://hostname/Jobs/add I can see a drop-down for user but its empty.
I’ve created few users which I can see from http://hostname/Users/

Why is drop-down empty? I am able to add jobs but when I view them, user field is shown empty.

Associations belong in the Model, not the controller.

In app/Model/User.php:

class User extends AppModel {
    public $name = 'User';
    public $hasMany = array('Job');
}

In app/Model/Job.php

class Job extends AppModel {
    public $name = 'Job';
    public $belongsTo = array('User');
}
