Hi all,

I need to create a field in invoice lines, with predefault = public_price but with the possibility to override this value.

Also, in case the product on the line is changed, the value must be updated.

I've tried with the following code, but it doesn't work:


    x_prod_list_price = fields.Float(required=False, related='product_id.list_price', readonly=False, store=False)


@api.multi
@api.onchange('product_id')
def _cust_onchange_product_id(self):
_logger.warning('_cust_onchange_product_id')
if not self.invoice_id:
_logger.warning('not self.invoice_id')
return
self.x_prod_list_price=self.product_id.list_price
_logger.warning('onchage prewrite x_prod_list_price = (%s)',self.product_id.list_price)
self.write({'x_prod_list_price': self.product_id.list_price})
_logger.warning('Onchage postwrite: (%s)', self.x_prod_list_price)
return




Any help?

If there is no need to present in view the x_prod_list_price with default value, You can set it's value in create(self,vals)
