我正在尝试使用 Profiles 和 Qualifications 表之间的 HABTM 关联。
型号:Profile.php
App::uses('AppModel', 'Model');
class Profile extends AppModel {
public $hasAndBelongsToMany = array(
'Qualification' => array(
'className' => 'Qualification',
'joinTable' => 'profile_qualifications',
'foreignKey' => 'profile_id',
'associationForeignKey' => 'qualification_id',
'unique' => 'keepExisting'
)
);
}
型号:Qualification.php
App::uses('AppModel', 'Model');
class Qualification extends AppModel {
public $hasAndBelongsToMany = array(
'Profile' => array(
'className' => 'Profile',
'joinTable' => 'profile_qualifications',
'foreignKey' => 'qualification_id',
'associationForeignKey' => 'profile_id',
'unique' => 'keepExisting',
)
);
}
控制器:ProfilesController.php
App::uses('AppController', 'Controller');
class ProfilesController extends AppController {
public function edit() {
$this->Profile->id = $this->Auth->user('profile_id');
if ($this->request->is('post') || $this->request->is('put')) {
if ($this->Profile->save($this->request->data)) {
$this->Session->setFlash(__('The profile has been saved'));
$this->redirect(array('action' => 'view'));
} else {
$this->Session->setFlash(__('The profile could not be saved. Please, try again.'));
}
} else {
$this->request->data = $this->Profile->read(null, $this->Auth->user('profile_id'));
}
$salutations = $this->Profile->Salutation->find('list', array('fields' => array('Salutation.id', 'Salutation.abbr_name')));
$qualifications = $this->Profile->Qualification->find('list', array('fields' => array('Qualification.id', 'Qualification.abbr_name')));
$this->set(compact('salutations', 'qualifications'));
}
}
查看:edit.ctp
<div class="profiles form">
<?php echo $this->Form->create('Profile'); ?>
<fieldset>
<legend><?php echo __('My Profile'); ?></legend>
<?php
echo $this->Form->input('salutation_id');
echo $this->Form->input('first_name');
echo $this->Form->input('middle_name');
echo $this->Form->input('last_name');
echo $this->Form->input('qualification'); /* gives drop down not multi select */
echo $this->Form->input('bio');
echo $this->Form->input('email');
echo $this->Form->input('mobile');
echo $this->Form->input('phone');
?>
</fieldset>
<?php echo $this->Form->end(__('Submit')); ?>
</div>
因此生成的编辑视图包含下拉菜单,可以一次选择一个值作为 Qualifications 属性。
我想知道如何为资格生成带有多值选择框的视图?此外,我的代码现在有什么错误?
