一个表单和多个模型

Question

我正在使用Yii框架。

目的：获取用户输入并将数据插入到表格Order和OrderDetail中。问题是数据仅插入到Order表中。我试图遵循wiki教程，但我无法解决这个问题。

为什么我不能将数据插入到两个表中，即Order和OrderDetail？

我有五款车型：

Customers(customer_id, customer_name, phone, email, lat, lng, ...) 
Products(product_id, product_name,price, ...) 
Order(order_id,customer_id, order_status, staff_id, ...) 
OrderDetail(order_detail_id, order_id,product_id, qty, ...) 
Staff(staff_id, staff_name, ...) 

OrderController.php

public function actionCreate() 
{ 
    $model=new Order; 
    $orderdetail=new OrderDetail(); 
    $product=new Products(); 

    $date=date('y-m-d'); 

    // Uncomment the following line if AJAX validation is needed 
    //$this->performAjaxValidation(array($model,$orderdetail)); 

    if(isset($_POST['Order'])) 
    { 

     $model->attributes=$_POST['Order']; 
      $model->lat='12.53'; 
      $model->lng='13.2'; 
      $model->completed_date=$date; 
      $model->received_date=$date; 
      $model->created_date=$date; 
      $model->upated_date=$date; 



     if($model->save()) 

     if(isset($_POST['OrderDetail'])){ 
     $orderdetail->attributes=$_POST['OrderDetail']; 
     $orderdetail->order_id= $model->order_id; 
     $orderdetail->order_item_status=1; 
     $orderdetail->created_date=$date; 
     $orderdetail->updated_date=$date; 

     if($orderdetail->save()) 
     $this->redirect(array('view','id'=>$model->order_id)); 
     } 

      //$OrderDetailController=new OrderDetail(); 
      //$this->redirect(array('OrderDetail/create')); 
    } 
    $this->render('create',array(
     'model'=>$model, 
     'orderdetail'=>$orderdetail, 
     'product'=>$product, 

    )); 
} 

的意见/顺序/ create.php

<?php 
$this->breadcrumbs=array(
    'Orders'=>array('index'), 
    'Create', 
); 

$this->menu=array(
    array('label'=>'List Order', 'url'=>array('index')), 
    array('label'=>'Manage Order', 'url'=>array('admin')), 
); 
?> 

<h1>Create Order</h1> 

<?php echo $this->renderPartial('_form', array('model'=>$model,'orderdetail'=>$orderdetail,'product'=>$product)); ?> 

的意见/顺序/ _form.php这个

<div class="form"> 

<?php $form=$this->beginWidget('CActiveForm', array(
    'id'=>'order-form', 
    'enableAjaxValidation'=>false, 
)); ?>

处理两个模型的表单...创建一个表单，其中包含两个模型的所有属性，然后在表单发布并有效时在视图中将属性保存到两个模型中。

if(isset($_POST['ModelOneAndModelTwoForm'])) 
{ 
    $form->attributes=$_POST['ModelOneAndModelTwoForm']; 

    if($form->validate()) 
    { 
     $modelOne = new ModelOne(); 
     $modelOne->save(); 

     $modelTwo = new ModelTwo(); 
     $modelTwo->save(); 
    } 
}
