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!
