Hi community, 

I tried to run a function (in odoo10) when the attribute "route_id" (in sale.order.line) is changed but nothing happens. Here my code : 

file sale_order.py

class saleOrder(models.Model):
    _inherit = 'sale.order'
    
    @api.multi
    @api.depends("order_line")
    def _compute_products(self):
        _logger.error('@@@@@@@@@')

def action_change_route_id(self):
    for line in self.order_line
        line.route_id = 3

class SaleOrderLine(models.Model):
    _inherit = 'sale.order.line'
    
    @api.onchange("route_id") #also tried with @api_depends("route_id")
    def on_change_route_id(self):
    _logger.error('________')
    self.order_id._compute_products()

Thank you
