Disable Buy button for unmanage product stocks that will be available in the future

nopCommerce version 3.0

I had to modify the PrepareProductVariantModel method to disable the buy button for product that are going to be available in the future.

            var nowUtc = DateTime.UtcNow;
            if (productVariant.AvailableStartDateTimeUtc > nowUtc)
            {
                model.AddToCart.DisableBuyButton = true;
                model.AddToCart.DisableWishlistButton = true;

                productVariant.ManageInventoryMethod = ManageInventoryMethod.ManageStock;
                productVariant.DisplayStockAvailability = true;
                productVariant.StockQuantity = 0;
                model.StockAvailability = productVariant.FormatStockMessage(_localizationService);
            }
