如何从sale_order_line onchange方法获取sale_order.id？ 在odoo 9

Question

I want to get the value of from a sale.order.line onchange method.

I have this code:

class SaleOrderLineExt(models.Model):
    _inherit = ['sale.order.line']

    @api.multi
    @api.onchange('my_field')
    def my_field_change(self):

        related_sale_order = self.order_id
        print 'related_sale_order: ', related_sale_order
        print 'related_sale_order.id: ', related_sale_order.id

But the output that I have is this:

related_sale_order: sale.order(<openerp.models.NewId object at 0x7f7566029810>,)
related_sale_order.id: <openerp.models.NewId object at 0x7f7566029810>

I can check other values of the sale order, but not the Id. Why is that and how can I get it?

Answer 1

in onchange method the frame pass d dummy object that have the values in the view in order to get the original record you do :

self._origin.related_sale_order.id

but you should keep in mind that the related sale order when you create a record is not yet saved in database you will keep getting the same result but in edit mode you will have the id.

Hope this helps you.

Try This

class SaleOrderLineExt(models.Model):
    _inherit = ['sale.order.line']

    @api.multi
    @api.onchange('my_field')
    def my_field_change(self):

        related_sale_order = self.order_id.id
        print "related_sale_order " related_sale_order
