Availability in prestashop 1.7 in checkout page

[beoutside]

Hello,

 

Do you know how to display the availability of the product on the cart-detailed-product-line.tpl on Prestashop 1.7.5.2?

The variable {product.quantity} is the quantity on the cart so Ican't use that.

My product are allowed out of stock. But I want an "In stock" label if the stock is > 0 and a "Pre-order" label if the quantity =< 0.

I can't use {$product.allow_oosp} because they are all allowed oosp.

Regards,
