how can i add multiple fields to invoice_vals['name_field'] =self.name_field(changing _prepare_invoice(self) in sale_order.py)?

Question

first im a novice in python
here is the code im using
@api.multi
def _prepare_invoice(self):
invoice_vals = super(SaleOrder, self)._prepare_invoice()
invoice_vals = {
'field1' : self.field1 ,
'field2' : self.field2
}
but it got me an account error
when i use only
invoice_vals['field1'] =self.field1
it works perfectly but i dont know how to add other field since i have 5 in total

Hi Blaise,
function _prepare_invoice from sale order returns a dict. If you want to add other values ( field1 and field2 in your case), you need to do this :
invoice_vals.update(field1=self.field1, field2=self.field2) If u have only one item to add, it is preferable, for me, to do this : invoice_vals['field1'] =self.field1
Upvote if this helps.
Thank you.
