Is there a way to retrieve discounts for a product in Craft Commerce v2? I would like to retrieve all available discounts for an eshop using the Craft Commerce v2.
In Craft Commerce v1, I could use the following:

craft.commerce.discounts.all()


However, I can't find an equivalent method for Commerce v2

Can anyone please help?
This should do what you're looking for:

craft.commerce.discounts.getAllDiscounts()


craft.commerce.discounts is a reference to services/Discounts, so you've got access to all of the public methods in there, of which getAllDiscounts() is one.
