Customizing child item form with embedRelation doctrine

Hi,

I am using symfony 1.3 and doctrine 1.2.

I have an embedRelation setup, with order and order_item in a schema somewhat like below (i have abbreviated):



Orders:

  columns:

    id: { type: integer(4), primary: true, autoincrement: true }

OrderItem:

   columns:

     id:                 { type: integer(4), primary: true, autoincrement: true }

     order_id:       { type: integer(4), primary: true, autoincrement: true }

     product_id:   { type: integer(4), primary: true, autoincrement: true }

     quantity:       { type: decimal(14) }

     price:            { type: decimal(10) }

    relations:

        Order:         { local: order_id, foreign: id }

        Product:      { local: product_id, foreign: id }        

Product:

   columns:

     id:                 { type: integer(4), primary: true, autoincrement: true }

     name:       { type: string(150) }

In a specific instance using my orders form and order_item form, I have created an embedRelation form to work with in a specific instance. I want to modify the orderItem listings in the embedRelation form so that it only displays product_id and price. However, presently when I update it, it overwrites "quantity" with blank value if I do not include it*. HOWEVER, I cannot modify orderItem form directly to unset values, as in other instances I need the full order_item form (at least this is what I have encountered thus far; perhaps someone else knows a better way).

I have lib/model/doctrine/OrderAssignForm.class.php



class OrderAssignForm extends OrdersForm

{

  public function configure()

  {

    $this->embedRelation('OrderItem');

  }

}

In form templates, I do (snippet of order item area)



<form action="<?php echo url_for('order_assign').'?id='.$form->getObject()->getId()?>">

  <?php echo $form->renderHiddenFields() ?>

  <?php echo $form->renderGlobalErrors() ?>



    <?php foreach ($form['OrderItem'] as $oi): ?>

      <?php echo $oi->renderHiddenFields() ?>

      <?php echo $oi['product_id']?>

      <?php echo $oi['price']->renderError() ?>

      <?php echo $oi['price'] ?><br/>

    <?php endforeach; ?>

But this causes quantity to be overwritten as null.

You *must* provide code to receive the award.

Wojciech Sznapka says:
Use inheritance :-)
Create EmbedOrderItemForm in lib/form/doctrine in which you will customize it, and then use as embedded form
```
class EmbedOrderItemForm extends OrderItemForm

{

  public function configure()

  {

    $this->useFields(array('displays product_id, 'price'));

  }

}
```
when embeding relation remember to pass form class:
```
$this->embedRelation ('OrderItem', 'EmbedOrderItemForm');
```

  Of course! I was trying to do this, just didn't know the syntax. Thank you!
