Odoo15拉取代码后打开单据报错：无法相减res.partner与res.users模型

问题描述 #

从Odoo 15.0仓库拉取最新代码后，打开销售订单及部分自定义对象记录时触发错误，错误信息：

TypeError: cannot substract different models: 'res.partner()' and 'res.users()'

无法定位具体错误位置，需确认是否为Odoo 15新版本BUG。

错误分析 #

从报错堆栈来看，错误发生在Odoo的表达式解析逻辑中，具体是parent_of_domain函数尝试对res.partner和res.users的记录集执行减法操作，而Odoo明确禁止不同模型的记录集进行此类运算。

这基本不是Odoo官方核心的BUG，官方代码不会出现这种跨模型操作的低级错误，更可能是以下原因导致：

• 自定义模块（如堆栈中出现的edoo_custom_treeview）修改了搜索逻辑，导致混用了不同模型的记录集。
• 自定义的搜索面板配置、域名过滤规则中，错误使用了parent_of操作符，传递了跨模型的参数。

排查与解决步骤 #

• 先禁用可疑自定义模块：优先禁用堆栈中出现的edoo_custom_treeview模块，重新测试是否还会触发错误。如果问题消失，说明该模块是错误源头，需要修复其代码逻辑，确保记录集操作的模型一致性。
• 检查搜索面板配置：查看销售订单及自定义对象的搜索面板，是否有针对用户或合作伙伴的层级过滤设置，确认是否错误关联了不同模型。
• 排查自定义域名逻辑：检查所有自定义模块中涉及parent_of操作符的域名代码，确保传递的记录集属于同一个模型。
