How do I get the account.invoice associated to a sales.order?

From sales.order object, how do I get the associated invoices?

I have tried to extend class stock.picking like this and added a function field:


payment_method = fields.Char(compute='_get_payment_terms',string='Payment Method',readonly=True)



def _get_payment_terms(self):

self.payment_method = self.sale_id.invoice_ids and self.sale_id.invoice_ids[0].payment_method_id and self.sale_id.invoice_ids[0].payment_method_id.name or ''

When loading the module it says: fields = [model._fields[head]] KeyError: 'payment_method_id'

Is there anything obvious I could be missing?

Hello E.M.,

There is a m2m field called "invoice_ids" in Sale Order which contains all the Invoices related to the SO.

I don't see "payment_method_id" field in account.invoice. Make sure you are using right field. I guess you want to show "Payment  Terms". For this you have to use "payment_term" field which is in "account.invoice".

Hope this will resolve your issue.


In the GUI, if you select an invoice and go to "Other information" tab, you will find there: payment_method. That is what I am trying to recover.

Yes, you are right. But you are using wrong field in your code. You should use "payment_term" instead of "payment_method_id".

i finally found that I just had to use payment_method, not payment_method_id. However, if I do that I just got "bank_transfer", how can I get the descriptive text "Bank Transfer"

WOW I forgot payment_method was actually an extension I wrote a few months ago. Requesting support for your own custom module seems like kinda audacious.
