如何在现有的odoo模块中添加颤振

我正在尝试在车辆服务日志中的车队中添加聊天记录 当我试图更新负责添加chatter的继承模块时，它给了我这个错误

这就是模型：

# -*- coding: utf-8 -*-
from odoo import models, fields, api

class Fleet_Chatter_service(models.Model):
    _name = 'fleet.chatter.service'
    _inherit = ['fleet.vehicle.log.services', 'mail.thread', 'ir.needaction_mixin']
    _description = "fleet chatter in cost and service"

这是一种观点：

<odoo>
    <record model="ir.ui.view" id="odt_fleet_service_chatter_form">
      <field name="name">odt.fleet.chatter.service</field>
      <field name="model">fleet.chatter.service</field>
      <field name="inherit_id" ref="fleet.fleet_vehicle_log_services_view_form"/>
      <field name="arch" type="xml">
          <xpath expr="//form/sheet" position="after">
              <div class="oe_chatter">
                  <field name="message_follower_ids" widget="mail_followers"/>
                  <field name="activity_ids" widget="mail_activity"/>
                  <field name="message_ids" widget="mail_thread" />
              </div>
          </xpath>
      </field>
    </record>
</odoo>

尝试继承“mail.activity.mixin”，因为它添加了您在视图中使用的“activity\u id”字段

#-*-编码：utf-8-*-
来自odoo导入模型、字段、api
机队级聊天服务（型号.型号）：
_name='fleet.chatter.service'
_继承=[
'车队.车辆.日志.服务'，'邮件.线程'，
'mail.activity.mixin'，'ir.needaction\u mixin'
]
_description=“车队在成本和服务方面的喋喋不休”
