我有这些模型：国家，州，城市，用户关系：国家有许多州，州有许多城市，城市有许多用户，
州属于国家，城市属于州，用户属于城市，
现在，我想获取所有用户，不仅包括他们的城市，还包括国家和州。我该怎么做？
控制器用户/索引：
public function index() {
$this->User->Behaviors->load('Containable');
$this->paginate = array('contain'=>array('State'));
debug($this->Paginator->paginate());exit;
$this->set('users', $this->Paginator->paginate());
}
输出：
Warning (512): Model "User" is not associated with model "State" [CORE\Cake\Model\Behavior\ContainableBehavior.php, line 342]
\app\Controller\UsersController.php (line 27)
array(
(int) 0 => array(
'User' => array(
'id' => '1',
'name' => 'username',
'city_id' => '1'
)
)
)
示范国家：
public $hasMany = array(
'State' => array(
'className' => 'State',
'foreignKey' => 'country_id',
'dependent' => false,
'conditions' => '',
'fields' => '',
'order' => '',
'limit' => '',
'offset' => '',
'exclusive' => '',
'finderQuery' => '',
'counterQuery' => ''
)
);
模型状态：
public $belongsTo = array(
'Country' => array(
'className' => 'Country',
'foreignKey' => 'country_id',
'conditions' => '',
'fields' => '',
'order' => ''
)
);
public $hasMany = array(
'City' => array(
'className' => 'City',
'foreignKey' => 'state_id',
'dependent' => false,
'conditions' => '',
'fields' => '',
'order' => '',
'limit' => '',
'offset' => '',
'exclusive' => '',
'finderQuery' => '',
'counterQuery' => ''
)
);
模范城市：
public $belongsTo = array(
'State' => array(
'className' => 'State',
'foreignKey' => 'state_id',
'conditions' => '',
'fields' => '',
'order' => ''
)
);
public $hasMany = array(
'User' => array(
'className' => 'User',
'foreignKey' => 'city_id',
'dependent' => false,
'conditions' => '',
'fields' => '',
'order' => '',
'limit' => '',
'offset' => '',
'exclusive' => '',
'finderQuery' => '',
'counterQuery' => ''
)
);
模型用户：
public $belongsTo = array(
'City' => array(
'className' => 'City',
'foreignKey' => 'city_id',
'conditions' => '',
'fields' => '',
'order' => ''
)
);
我已经解决了。感谢cakephp社区。控制器用户/索引
public function index() {
//$this->User->recursive = 3;
$this->User->Behaviors->load('Containable');
/* $user = $this->User->find('all', array(
'contain' => array(
'City.name' => array(
'State.name'=>array('Country.name')
))));
debug($user);exit;
*/
$this->paginate = array('contain'=>array('City'=>array('State'=>array('Country'))));
//debug($this->Paginator->paginate());exit;
$this->set('users', $this->Paginator->paginate());
}
查看用户/索引
<table cellpadding="0" cellspacing="0">
<thead>
<tr>
<th><?php echo $this->Paginator->sort('id'); ?></th>
<th><?php echo $this->Paginator->sort('name'); ?></th>
<th><?php echo $this->Paginator->sort('city_id'); ?></th>
<th><?php echo $this->Paginator->sort('state_id'); ?></th>
<th><?php echo $this->Paginator->sort('country_id'); ?></th>
<th class="actions"><?php echo __('Actions'); ?></th>
</tr>

<tbody>
<?php foreach ($users as $user): ?>
<tr>
<td><?php echo h($user['User']['id']); ?> </td>
<td><?php echo h($user['User']['name']); ?> </td>
<td>
<?php echo $this->Html->link($user['City']['name'], array('controller' => 'cities', 'action' => 'view', $user['City']['id'])); ?>
