私は http://book.cakephp.org/2.0/en/tutorials-and-examples/simple-acl-managed-application/simple-acl-managed-application.htmlチュートリアルに従っています。グループとユーザー アカウントを追加します...
しかし、新しいユーザーを追加するためにアクセスすると、グループのドロップダウンが空です...何が問題なのですか?
User.php モデルは次のようになります
<?php
App::uses('AppModel', 'Model');
/**
* User Model
*
* @property Group $Group
* @property Image $Image
*/
App::uses('AuthComponent', 'Controller/Component');
class User extends AppModel {
/**
* Display field
*
* @var string
*/
//The Associations below have been created with all possible keys, those that are not needed can be removed
public $actsAs = array('Acl' => array('type' => 'requester'));
public function beforeSave() {
$this->data['User']['password'] = AuthComponent::password($this->data['User']['password']);
return true;
}
public function bindNode($user) {
return array('model' => 'Group', 'foreign_key' => $user['User']['group_id']);
}
public function parentNode() {
if (!$this->id && empty($this->data)) {
return null;
}
if (isset($this->data['User']['group_id'])) {
$groupId = $this->data['User']['group_id'];
} else {
$groupId = $this->field('group_id');
}
if (!$groupId) {
return null;
} else {
return array('Group' => array('id' => $groupId));
}
}
public $belongsTo = array(
'Group' => array(
'className' => 'Group',
'foreignKey' => 'group_id',
'conditions' => '',
'fields' => '',
'order' => ''
)
);
public $hasMany = array(
'Image' => array(
'className' => 'Image',
'foreignKey' => 'user_id',
'dependent' => false,
'conditions' => '',
'fields' => '',
'order' => '',
'limit' => '',
'offset' => '',
'exclusive' => '',
'finderQuery' => '',
'counterQuery' => ''
)
);
}
Group.php モデルは次のようになります。
<?php
App::uses('AppModel', 'Model');
/**
* Group Model
*
* @property User $User
*/
class Group extends AppModel {
/**
* Display field
*
* @var string
*/
public $displayField = 'name';
/**
* Validation rules
*
* @var array
*/
//The Associations below have been created with all possible keys, those that are not needed can be removed
/**
* hasMany associations
*
* @var array
*/
public $actsAs = array('Acl' => array('type' => 'requester'));
public function parentNode() {
return null;
}
public $hasMany = array(
'User' => array(
'className' => 'User',
'foreignKey' => 'group_id',
'dependent' => false,
'conditions' => '',
'fields' => '',
'order' => '',
'limit' => '',
'offset' => '',
'exclusive' => '',
'finderQuery' => '',
'counterQuery' => ''
)
);
}
私のテーブルはこの「ユーザー」テーブルのように見えます
> > Field Type Null Key Default Extra
> > id int(11) NO PRI NULL auto_increment
> > username varchar(64) NO UNI NULL password varchar(82) NO NULL
> > first_name varchar(64) NO NULL last_name varchar(64) NO NULL
> > created datetime YES NULL group_id int(11) NO NULL
「グループ」テーブル
Field Type Null Key Default Extra
id int(11) NO PRI NULL auto_increment
name varchar(100) NO NULL
created datetime YES NULL
modified datetime YES NULL
View/Users/add.ctp コード
<div class="users form">
<?php echo $this->Form->create('User');?>
<fieldset>
<legend><?php echo __('Add User'); ?></legend>
<?php
echo $this->Form->input('username');
echo $this->Form->input('password');
echo $this->Form->input('first_name');
echo $this->Form->input('last_name');
echo $this->Form->input('group_id');
?>
</fieldset>
<?php echo $this->Form->end(__('Submit'));?>
</div>
<div class="actions">
<h3><?php echo __('Actions'); ?></h3>
<ul>
<li><?php echo $this->Html->link(__('List Users'), array('action' => 'index'));?></li>
<li><?php echo $this->Html->link(__('List Groups'), array('controller' => 'groups', 'action' => 'index')); ?> </li>
<li><?php echo $this->Html->link(__('New Group'), array('controller' => 'groups', 'action' => 'add')); ?> </li>
<li><?php echo $this->Html->link(__('List Images'), array('controller' => 'images', 'action' => 'index')); ?> </li>
<li><?php echo $this->Html->link(__('New Image'), array('controller' => 'images', 'action' => 'add')); ?> </li>
</ul>
</div>
2つのグループを作成しました。1 つは「訪問者」で、もう 1 つは「管理者」です。aros現在、テーブルは次のように表示されます。
id parent_id model foreign_key alias lft rght
2 NULL Group 4 1 2
3 NULL Group 5 3 4
