Product variant id

Hi,

I am trying to figure out if is possible to retrieve the product variant ID inside my product detail view template.

In other words I have a product with variations and before i add to cart a product variant i would like to get his id.

Is it possible?

Also i am trying to use the function

perch_shop_product_variants(perch_get('item'));

but it seems that doesn't work for me. I have perch (2.8.32) and shop (1.0.10) to the latest versions.

here the debug if i try to use that function:

Using template: /addons/apps/perch_shop/templates/shop/products/variant_list.html

perch_get('item') is my product slug.

Thanks, Vince.
