Magento – Can’t Set Default Value for ‘Weight’ Attribute

After trying out again, messing up a lot and finally finding the correct answer, this works:

$entityTypeId = Mage::getModel('catalog/product')
                  ->getResource()
                  ->getEntityType()
                  ->getId(); //product entity type

$attributeSet = Mage::getModel('eav/entity_attribute_set')
                  ->setEntityTypeId($entityTypeId)
                  ->setAttributeSetName("test_set");

$attributeSet->validate();
$attributeSet->save();

$attributeSet->initFromSkeleton($entityTypeId)->save();

You need to save before you do initFromSekeleton(). Otherwise it just won't work.

To answer the question:

Thanks to some handy built-in methods you don't have to do any loading on your own:

• Mage_Sales_Model_Order_Shipment_Item provides getOrderItem
• Mage_Sales_Model_Order_Item provides getProduct

So, all you should have to do is this:

$product = $shipmentItem->getOrderItem()->getProduct();

If size is persisted to the order item, you can do:

$item = $shipmentItem->getOrderItem();
echo $item->getAttributeText('size');

Or, if you need to load the ID value from the product itself, you can get all of the product's selected ID values:

$size = $shipmentItem->getOrderItem()->getProduct()->getSize();
