PS 1.7, attributes on a products-list.tpl

[mipapage]

Hello everyone,

We are upgrading to 1.7 from 1.6. In PS 1.6, we were able to extend CategoryControllerCore and use the following code to get product attribute data to show in the list views (based somewhat on this code from @NemoPS)

$attributes_combinations = Product::getAttributesInformationsByProduct($product['id_product']);

After a bit of looping and wrangling, that code went to Smarty to be used on products-list.tpl:

$this->context->smarty->assign('products', $this->cat_products);

The same bit of code does absolutely nothing in PS 1.7. We need to get the attribute data, because some of our products are available in different lot sizes. 

In 1.7 I notice that class CategoryControllerCore extends ProductListingFrontController, whereas in 1.6 class CategoryControllerCore extends FrontController.

So yeah. I don't have it clear where this should be done, and I'm guessing the best answer would be to use a hook (actionGetProductPropertiesBefore or after?) rather than an override.

I would be very grateful if someone could point me in the right direction. Thanks!
