值错误：字段不存在 [Odoo 12]

Question

我正试图从account.invoice模块的销售订单中获取client_order_ref。我不知道为什么它说这个域不存在，它定义了这个域。请帮我

Python代码

from odoo import models, fields, api, _
class AccountInvoice(models.Model):
_inherit = 'account.invoice'
client_order_ref = fields.Char(string="Client Order Ref", compute="get_client_from_sale_order")
@api.depends('name')
def get_client_from_sale_order(self):
self.ensure_one()
for rec in self:
sale_order = self.env['sale.order'].search(
[('name', '=', rec.origin)]
)
rec.client_order_ref = sale_order.client_order_ref

XML代码

<?xml version="1.0" encoding="utf-8"?>
<odoo>
<record id="invoice_tree" model="ir.ui.view">
<field name="name">account_invoice_tree_inherit</field>
<field name="model">account.invoice</field>
<field name="inherit_id" ref="account.invoice_tree"/>
<field name="arch" type="xml">
<xpath expr="//field[@name='partner_id']" position="after">
<field name="client_order_ref"/>
</xpath>
</field>
</record>
</odoo>

Answer 1

我想，您忘记了从odoo模型继承的一个重要点。。。当你在odoo的模块中的现有模型上添加一个新字段时，首先你必须用命令升级你的模块，而不是用odoo接口。。。只需运行以下命令：./odoo-bin -c /etc/odoo-server.conf -d data_base_name -u module_name我希望这对你有帮助。
