Odoo 16自定义Conversation频道报错及消息发送问题求助

问题背景 #

尝试在Odoo 16中创建自定义Conversation频道，完成以下操作后升级模块报错：

• 在my_module/data/下创建custom_channels.xml，内容如下：

<?xml version="1.0" encoding="utf-8" ?>
<odoo>
    <data noupdate="1">
        <record id="channel_mailing" model="mail.channel">
            <field name="name">Mailing queue reports</field>
            <field name="description">Mailing tasks status and history</field>
            <field name="public">groups</field>
            <field name="group_public_id" ref="project.group_project_manager"/>
            <field name="group_ids" eval="[Command.link(ref('project.group_project_manager'))]"/>
        </record>
    </data>
</odoo>

• 在模块Manifest文件中配置数据文件：

'data': [
    'security/ir.model.access.csv',
    'views/menu.xml',
    'data/mailing_queue_channel.xml',
],

重启服务器升级模块时，触发KeyError: 'mail.channel'，完整报错栈如下：

Traceback (most recent call last):
  File "/home/useruser/Desktop/odoo_dev/16.0/odoo/odoo/tools/convert.py", line 698, in _tag_root
    f(rec)

    model = env[rec_model]

  File "/home/useruser/Desktop/odoo_dev/16.0/odoo/odoo/modules/registry.py", line 190, in __getitem__
    return self.models[model_name]
KeyError: 'mail.channel'

The above exception was the direct cause of the following exception:

解决步骤 #

1. 添加模块依赖
   在模块的Manifest文件中，找到'depends'列表，添加'mail'模块（mail.channel模型属于mail模块，必须声明依赖才能加载该模型）。修改后的Manifest示例：

'depends': ['base', 'project', 'mail'],
'data': [
    'security/ir.model.access.csv',
    'views/menu.xml',
    'data/custom_channels.xml',  # 修正为实际文件名
],

2. 修正数据文件名
   创建的文件是custom_channels.xml，但Manifest中配置的是mailing_queue_channel.xml，文件名不匹配会导致Odoo无法找到该文件，需将Manifest中的路径改为实际文件名。

3. 重新升级模块
   保存修改后，重启Odoo服务器，进入模块列表找到自定义模块，点击升级按钮完成更新。

原因说明 #

Odoo按依赖顺序加载模块，若未声明依赖mail模块，加载当前模块时mail.channel模型还未注册，就会触发KeyError。同时文件名不匹配会导致数据文件无法被正确加载，引发解析错误。
