Yii从两个模型收集数据成单一形式

Question

In my web application I need to collect data from two models in a single form. The first model form is like an update action for making changes in existing data and the second form is for creating a new record. Below is the code I tried but when I click "save" button Its not saving and redirecting instead it is just staying in the same page and the changes I made are reverting back to their previous values for I model and second model the attribute are becoming empty.

My code for the controller

public function actionBookvegetable($id){
    $BookVegetable=new BookVegetable;
    $model=$this->loadModel($id);

        if(isset($_POST['ProducerOffer'])AND (isset($_POST['BookVegetable'])) ) {



        $model->attributes=$_POST['ProducerOffer'];
        $BookVegetable->attributes=$_POST['BookVegetable'];
        if($ProducerOffer->validate()  AND  $BookVegetable->validate()) {
            $BookVegetable->save();



        $BookVegetable->booked_by=Yii::app()->user->id;
        $BookVegetable->producer_offer_id=$model->id;

        $model->save();

        }
        if (($model->hasErrors() === false)&&($BookVegetable->hasErrors===false))
        {
            $this->redirect(Yii::app()->user->returnUrl);
          }
    }
        else
        {

            Yii::app()->user->setReturnUrl($_GET['returnUrl']);
        }
        $this->render('book',array('model'=>$model,'BookVegetable'=>$BookVegetable));
        }

My code for the view form.

<?php $form=$this->beginWidget('bootstrap.widgets.TbActiveForm',array('id'=>'non-ajax_form','enableAjaxValidation'=>false,)); ?>
<p class="help-block">Fields with <span class="required">*</span> are required.</p>

<?php echo $form->errorSummary($model,$BookVegetable); ?>
<?php echo "<br>" ?>

<?php echo $form->dropDownList($model,'vegetable_id', CHtml::listData(Vegetable::model()->findAll(),'id', 'name'), array('prompt'=>'Select Vegetable')); ?>


<?php echo CHtml::encode($model->getAttributeLabel('offered_qty')); ?>

<?php echo CHtml::textField("offered_qty",$model->offered_qty,array('readonly'=>true)); ?>


<?php echo CHtml::encode($model->getAttributeLabel('unit_cost')); ?>

<?php echo CHtml::textField("unit_cost",$model->unit_cost,array('readonly'=>true)); ?>

<?php echo CHtml::encode($model->getAttributeLabel('unit_delivery_cost')); ?>


<?php echo CHtml::textField("unit_delivery_cost",$model->unit_delivery_cost,array('readonly'=>true)); ?>
<?php echo CHtml::textField("booked_quantity",$BookVegetable->booked_quantity); ?>


</div>
<?php $this->endWidget(); ?>
</div>  





<div class="form-actions">
    <?php $this->widget('bootstrap.widgets.TbButton', array('buttonType'=>'submit', 'type'=>'primary', 'label'=>  'Save',)); ?

How should I resolve this Anybody help me out .I am unable to debug the source of error

You are saving the values before assigning the requested values.

Try this code, if it works:

public function actionBookvegetable($id){
    $BookVegetable=new BookVegetable;
    $model=$this->loadModel($id);
    if(isset($_POST['ProducerOffer'])AND (isset($_POST['BookVegetable'])) ) 
    {
        $model->attributes=$_POST['ProducerOffer'];
        $BookVegetable->attributes= $_POST['BookVegetable'];

        /*** The below two lines should be before "$BookVegetable->save()" function ***/
        $BookVegetable->booked_by=Yii::app()->user->id;
        $BookVegetable->producer_offer_id=$model->id;

        /*** Validate() function will check for the errors **/
        if($ProducerOffer->validate()  AND  $BookVegetable->validate()) 
        {
            $BookVegetable->save();
            $model->save();
            $this->redirect(Yii::app()->user->returnUrl);
        }
        /***There is no need to check again for the errors as validate() will do that, So you can comment this three lines ***/
        /**if (($model->hasErrors() === false)&&($BookVegetable->hasErrors===false))
        {
        $this->redirect(Yii::app()->user->returnUrl);
        } */
    }
    else
    {
        Yii::app()->user->setReturnUrl($_GET['returnUrl']);
    }
    $this->render('book',array('model'=>$model,'BookVegetable'=>$BookVegetable));
}

Try changing these input text fields in your view file:

<?php echo $form->dropDownList($model,'vegetable_id', CHtml::listData(Vegetable::model()->findAll(),'id', 'name'), array('prompt'=>'Select Vegetable')); ?>

 /*** The first field for below input text field is for "name" of the text fields, so this must follow "ModelName[field_name]" format **/
<?php echo CHtml::textField("ProducerOffer[offered_qty]",$model->offered_qty,array('readonly'=>true)); ?>


<?php echo CHtml::textField("ProducerOffer[unit_cost]",$model->unit_cost,array('readonly'=>true)); ?>

<?php echo CHtml::textField("ProducerOffer[unit_delivery_cost]",$model->unit_delivery_cost,array('readonly'=>true)); ?>

<?php echo CHtml::textField("BookVegetable[booked_quantity]",$BookVegetable->booked_quantity); ?>

I hope this would definitely work.. :)
