Hello all,
I'm in the model account.invoice, in a new method.
An invoice has an origin sale order.
Trying to get the id of the origin sale_order of an invoice.
Is this the best and cleanest way to get this id?
class AccountInvoice(models.Model):
_inherit = "account.invoice"
def get_origin_sale_order_id(self):
sale_order_id = self.env['sale.order'].search([('name', '=', self.origin)])[0].id
return sale_order_id
Thanks for your comments!
No, it's not.
You can do like this.
This will work for you.
sale_order_id = self.invoice_line_ids.mapped('sale_line_ids').order_id
It works! However I got expected singleton error if there are multiple sale.order.line lines
Here is my source code to overcome this error:
sale_line_ids = self.invoice_line_ids.mapped('sale_line_ids')
if sale_line_ids:
sale_order = sale_line_ids[0].order_id
If we think straightway, it's not possible that one invoice is created for 2 sale orders.
