我是蛋糕新手,使用的是第 2 版。
我有模型
hgcylinder.php
class HgCylinder extends AppModel {
//put your code here
var $name= "HgCylinder";
var $belongsTo = array('HgKeyGase');
}
hgkeygase.php
class HgKeyGase extends AppModel {
//put your code here
var $name= "HgKeyGase";
public $belongsTo = array(
'HgKeyColor' => array(
'className' => 'HgKeyColor',
'foreignKey' => 'hg_key_color_id',
'conditions' => '',
'fields' => '',
'order' => ''
)
);
}
Controller HgCylindersController.php
<?php
class HgCylindersController extends AppController
{
var $name = "HgCylinders";
// var $scaffold;
function index()
{
$this->set('hey',$this->HgCylinder->find('all'));
}
public function edit($id = null) {
$this->HgCylinder->id = $id;
if ($this->request->is('post')) {
var_dump($this->request->data);
exit;
if ($this->HgCylinder->save($this->request->data)) {
$this->Session->setFlash(__('Cylinder has been updated successfull'));
$this->redirect(array('action' => 'index'));
} else {
$this->Session->setFlash(__('The cylinder could not be saved. Please, try again.'));
}
} else {
$this->request->data = $this->HgCylinder->read(null, $id);
}
$hg_key_gase_id = $this->HgCylinder->HgKeyGase->find('list');
$this->set(compact('hg_key_gase_id'));
}
}
?>
View : edit.ctp
<?php
echo $this->form->create('HgCylinder',array('action'=>'edit'));
echo $this->form->input('hg_key_gase_id',);
echo $this->form->input("capacityM3");
echo $this->form->input("weightEmpty");
echo $this->form->input("weightFilled");
echo $this->form->input("isFilled");
echo $this->form->end('Add');
?>
我的问题是 hg_key_gase_id 成为没有选项的选择列表。如果我在视图和控制器中将名称更改为“hgKeyGas”,它会显示 hg_key_gases 表中的选项。但是在保存时不会将 hg_key_gase_id 字段的值保存在 hg_cylinders 表中,而是在该字段中存储 null。
其次,我想知道有必要将变量名称从控制器传递给视图,与表中的字段完全相同。
