[trunk/7.0] product_visible_discount doesn't update price_unit on UOM change

[Grover Menacho]

On product_visible_discount the function get_real_price is not considering UOM.

I have a product with uom_id = 'Unit(s)' with price of 12
When I change the uom to dozen on sale_order, get_real_price returns 12 too.

I've detected why.

            factor = 1.0
            if uom_id and uom_id != product.uom_id.id:
                product_uom_obj = self.pool.get('product.uom')
                uom_data = product_uom_obj.browse(cr, uid, product.uom_id.id)
                factor = uom_data.factor
            return product_read[field_name] * factor

If your product_id.uom is unit even if you change uom on sale_order this is pulling the factor only from product_id uom. So it's going to be 1.

The fix must be:

            factor = 1.0
            if uom_id and uom_id != product.uom_id.id:
                product_uom_obj = self.pool.get('product.uom')
                uom_data = product_uom_obj.browse(cr, uid, product.uom_id.id)
                factor_uom = product_uom_obj.browse(cr, uid, uom).factor
                factor_product=uom_data.factor
                factor=factor_product/factor_uom
            return product_read[field_name] * factor
