I have overriden the product.packagings table to move from product.template to product.product where it should be (check \Github issue #8237).

Now I want to display packaging info on the website for each variant (aka product.product).

I insert a very crude qweb to test:

<table>

    <tbody>

         <t t-foreach="product.product_variant_ids[0].packaging_ids" t-as="packaging_id">

               <tr>

                    <td>​<span t-field="packaging_id.ean"/></td>

                    <td>​<span t-field="packaging_id.qty"/></td>

               </tr>

         </t>

      </tbody>

</table>

It works but (as expected) fetches values for the first variant found. I want the table to change according to the variant selected from the combination of variant values.

The problem here is that I didn't find the selected variant_id as it is built dynamically in javascript (by evaluating attribute value selections).

• Is there a way to get the variant_id (product_id in website_sale.js) exposed as a variable in qweb so that I can use:

<t t-foreach="variant_id.packaging_ids" t-as="packaging_id">

• How can I auto-update the table when the variant changes?
