And for the `create` view, we would need the following code,
 
 
 
```php 
<?php echo CHtml::form(); ?>
 
//create.php
To add these new fields to your Create form, add your 2nd table fields no stored in a 2nd model.  
 
 
A's create.php:
 
 
 
 
 
```php <?php echo $this->renderPartial('_form', array('a'=>$a, 'b'=>$b)); ?> // _form.php
 
```
 
 
 
You usually place the specific fileds in the _form.php file if you are working off Gii created CRUD files.
 
 
 
```php 
<?php echo CHtml::beginForm(); ?>
 
 
    <?php echo CHtml::errorSummary(array($a,$b)); ?>     <!-- ...input fields for $a, $b...
 
 
</form>
 
```
 
 
The above approach can also be used if we have more than two models to deal with.
