背景：我开发了一个新模块，想为几个模型继承 res.partner。我通过从__init__.py 中取出除此测试模型之外的所有模型来缩小范围：

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

class Testmodel(models.Model):
    _name = 'module_name.testmodel'
    _inherit = 'res.partner'

我还删除了__openerp__.py 中的所有视图。

似乎继承是导致此问题的原因。我尝试将其更改为_inherits = {'res.partner': 'partner_id'}，然后错误不再显示，但我不想要那种继承。我想要的结果是一个包含 res.partner 的所有字段的测试模型，但作为数据库中的一个单独模型，就像这张图片中所谓的 原型继承：https://odoo-80.readthedocs.org/en/latest/reference/orm.html

如果我编辑现有合作伙伴并尝试为其分配现有母公司，则会显示相同的错误消息。

【问题讨论】：

在创建module_name.testmode' 对象或res.partner 模型时是否遇到错误？
在创建res.partner 模型时发生。测试模型的创建工作正常。
嗯。这对我来说看起来不错。您如何尝试使用新数据库？
是的，我刚刚用一个新的数据库尝试过，但它不起作用。卸载后，我可以再次创建联系人。

【解决方案1】：

尝试在清单文件中依赖res.partner :)

in __openerp__.py
{...
'depends': ["base",],
...
}

【讨论】：

提供如何做到这一点似乎过于简单和不必要，但实际上它会带来更好的答案。

【解决方案2】：

从project.task 继承时我遇到了类似的问题，结果是一个错误。我通过编辑函数_hours_get 解决了这个问题（在你的情况下，它将是_get_latest）。该函数正在访问来自为空的数据库查询的结果，但它没有验证该结果包含的内容。

所以我希望您可以通过更正 _get_latest 中的代码来解决您的问题。
