php - 如何通过在 cakephp 2.x 中使用可包含行为来获取国家、城市、州的用户

Question

我有这些型号:国家、州、城市、用户与关系:国家有很多州，该州有许多城市，城市有很多用户，

州属于国家/地区，城市属于州，用户所属城市，

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。 我怎样才能做到这一点？

Controller 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'
        )
    )
)

型号国家:

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' => ''
        )
    );

型号城市:

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' => ''
    )
);

型号用户:

public $belongsTo = array(
    'City' => array(
        'className' => 'City',
        'foreignKey' => 'city_id',
        'conditions' => '',
        'fields' => '',
        'order' => ''
    )
);

我已经解决了。感谢 cakephp 社区。 Controller 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 $this->Paginator->sort('country_id'); ?></th>
            <th class="actions"><?php echo __('Actions'); ?></th>
    </tr>
    </thead>
    <tbody>
    <?php foreach ($users as $user): ?>
    <tr>
        <td><?php echo h($user['User']['id']); ?>&nbsp;</td>
        <td><?php echo h($user['User']['name']); ?>&nbsp;</td>
        <td>
            <?php echo $this->Html->link($user['City']['name'], array('controller' => 'cities', 'action' => 'view', $user['City']['id'])); ?>

        </td>

        <td>

            <?php echo $this->Html->link($user['City']['State']['name'], array('controller' => 'states', 'action' => 'view', $user['City']['State']['id'])); ?>
                </td>

        <td>

            <?php echo $this->Html->link($user['City']['State']['Country']['name'], array('controller' => 'countries', 'action' => 'view', $user['City']['State']['Country']['id'])); ?>
        </td>

    </tr>
<?php endforeach; ?>
    </tbody>
    </table>
