odoo14用odoobot给指定用户发消息

1.发送私聊消息最佳写法

def _send_sys_message(self, user, message):
    """通过OdooBot给指定用户发送消息
    :param user: 'res.users' 对象
    :param message: str, 消息内容
    """
    # 获取OdooBot的partner_id
    odoobot_id = self.env['ir.model.data'].xmlid_to_res_id("base.partner_root")
 
    # 获取OdooBot和用户的聊天频道
    channel_partners = user.mapped('partner_id').ids
    channel = self.env['mail.channel'].sudo().search(
        [('channel_type', '=', 'chat'), ('channel_partner_ids', 'in', channel_partners),('channel_partner_ids', 'in', [odoobot_id])], limit=1)
 
    # 不存在则初始化聊天频道
    if not channel:
        user.odoobot_state = 'not_initialized'
        channel = self.env['mail.channel'].with_user(user).init_odoobot()
    # 发送消息
    channel.sudo().message_post(
        body=message,
        author_id=odoobot_id,
        message_type="comment",
        subtype_xmlid="mail.mt_comment",
    )

2.发送群聊消息

@ormcache('odoobot_id')
def _get_channel(self,odoobot_id):
    # find if a channel was opened for this user before
    channel = self.env['mail.channel'].sudo().search([
        ('name', '=', '接口推送'),
        ('channel_partner_ids', 'in', [self.env.user.partner_id.id])
    ],
        limit=1,
    )
    _logger.info(f'find exist channer:{channel}')
    if not channel:
        # create a new channel
        channel = self.env['mail.channel'].with_context(mail_create_nosubscribe=True).sudo().create({
            'channel_partner_ids': [(4, self.env.user.partner_id.id), (4, odoobot_id)],
            'public': 'groups',  # 谁能关注组的活动
            'channel_type': 'channel',  # 渠道,群聊
            'group_public_id': self.env.ref('base.group_user').id,  # 经授权的群组
            'group_ids': [(6, 0, [self.env.ref('api_log.api_log_user_group').id])],  # 自动订阅组
            'email_send': False,
            'name': f'接口推送',
            'description': '用于群发接口调用相关的消息,调用日志写入接口日志表时会自动发消息通知群里',
            'display_name': f'接口推送',
        })
        _logger.info(f'create an api channel id: {channel}')
    return channel.id
 
def _send_group_message(self, message):
    """
    发送群聊渠道消息
    """
    # 获取OdooBot的partner_id
    odoobot_id = self.env['ir.model.data'].sudo().xmlid_to_res_id("base.partner_root")
 
    # find if a channel was opened for this user before
    channel_id = self._get_channel(odoobot_id)
    channel = self.env['mail.channel'].browse(channel_id)
    # 给群组发消息
    channel.sudo().message_post(
        body=message,
        author_id=odoobot_id,
        message_type="comment",
        subtype="mail.mt_comment",
    )
