如何使用cakephp 2.x中的可包含行为获取国家、城市、州的用户
如何使用cakephp 2.x中的可包含行为获取国家、城市、州的用户
提问于 2015-04-30 07:33:54
我有这样的模型：Country，State，City，User with relations：Country hasMany State，State hasMany City，City hasMany User，
State belongsTo Country，City belongsTo State，User belongsTo City，
现在我想把所有的用户，不仅是他们的城市，而且是国家和州。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'
)
)
)Model Country：
public $hasMany = array(
'State' => array(
'className' => 'State',
'foreignKey' => 'country_id',
'dependent' => false,
'conditions' => '',
'fields' => '',
'order' => '',
'limit' => '',
'offset' => '',
'exclusive' => '',
'finderQuery' => '',
'counterQuery' => ''
)
);Model State：
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' => ''
)
);模型City：
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' => '',

'order' => '',
'limit' => '',

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

我已经决定了。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 $this->Paginator->sort('country_id'); ?></th>
<th class="actions"><?php echo __('Actions'); ?></th>
</tr>
</thead>
<tbody>
<?php foreach ($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'])); ?>
</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; ?>
